Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Rhine
–
The largest city on the river Rhine is Cologne, Germany, with a population of more than 1,050,000 people. It is the second-longest river in Central and Western Europe, at about 1,230 km, with an average discharge of about 2,900 m3/s. The Rhine and the Danube formed most of the inland frontier of the Roman Empire and, since those days. The many castles and fortifications along the Rhine testify to its importance as a waterway in the Holy Roman Empire, in the modern era, it has become a symbol of German nationalism. The variant of the name of the Rhine in modern languages are all derived from the Gaulish name Rēnos, spanish is with French in adopting the Germanic vocalism Rin-, while Italian, Occitan and Portuguese retain the Latin Ren-. The Gaulish name Rēnos belongs to a class of river names built from the PIE root *rei- to move, flow, run, the grammatical gender of the Celtic name is masculine, and the name remains masculine in German, Dutch and French. The Old English river name was variously inflected as masculine or feminine, the length of the Rhine is conventionally measured in Rhine-kilometers, a scale introduced in 1939 which runs from the Old Rhine Bridge at Constance to Hoek van Holland. The river length is shortened from the rivers natural course due to a number of canalisation projects completed in the 19th and 20th century. The total length of the Rhine, to the inclusion of Lake Constance and its course is conventionally divided as follows, The Rhine carries its name without distinctive accessories only from the confluence of the Vorderrhein and Hinterrhein near Tamins-Reichenau. Above this point is the catchment of the headwaters of the Rhine. It belongs almost exclusively to the Swiss Canton of Graubünden, ranging from Gotthard Massif in the west via one valley lying in Ticino, traditionally, Lake Toma near the Oberalp Pass in the Gotthard region is seen as the source of the Vorderrhein and the Rhine as a whole. The Hinterrhein rises in the Rheinwald valley below Mount Rheinwaldhorn, the Vorderrhein, or Anterior Rhine, springs from Lai da Tuma, near the Oberalp Pass and passes the impressive Ruinaulta formed by the largest visible rock slide in the alps, the Flims Rockslide. A multiday trekking route is signposted along the young Rhine called Senda Sursilvana, the Hinterrhein/Rein Posteriur, or Posterior Rhine, starts from the Paradies Glacier, near the Rheinwaldhorn. One of its tributaries, the Reno di Lei, drains the Valle di Lei on politically Italian territory, after three main valleys separated by the two gorges, Roflaschlucht and Viamala, it reaches Reichenau. The Vorderrhein arises from numerous source streams in the upper Surselva, one source is Lai da Tuma with the Rein da Tuma, which is usually indicated as source of the Rhine, flowing through it. Into it flow tributaries from the south, some longer, some equal in length, such as the Reno di Medel, the Rein da Maighels, and the Rein da Curnera. The Cadlimo Valley in the Canton of Ticino is drained by the Reno di Medel, all streams in the source area are partially, sometimes completely, captured and sent to storage reservoirs for the local hydro-electric power plants. In its lower course the Vorderrhein flows through a gorge named Ruinaulta through the Flims Rockslide, the whole stretch of the Vorderrhein to the Rhine confluence near Reichenau-Tamins is accompanied by a long-distance hiking trail called Senda Sursilvana

Cologne is the largest city in the German federal State of North Rhine-Westphalia and the fourth-largest city in Germany. It is located within the Rhine-Ruhr metropolitan region, one of the major European metropolitan areas, and with more than ten million inhabitants, Cologne is located on both sides of the Rhine River, less than eighty kilometres from Belgium. The citys famous Cologne Cathedral is the seat of the Catholic Archbishop of Cologne, the University of Cologne is one of Europes oldest and largest universities. Cologne was founded and established in Ubii territory in the first century AD as the Roman Colonia Claudia Ara Agrippinensium, Cologne, the French version of the citys name, has become standard in English as well. The city functioned as the capital of the Roman province of Germania Inferior, during the Middle Ages it flourished on one of the most important major trade routes between east and west in Europe. Cologne was one of the members of the Hanseatic League and one of the largest cities north of the Alps in medieval. Up until World War II the city had several occupations by the French. Cologne was one of the most heavily bombed cities in Germany during World War II, the bombing reduced the population by 95%, mainly due to evacuation, and destroyed almost the entire city. With the intention of restoring as many buildings as possible. Cologne is a cultural centre for the Rhineland, it hosts more than thirty museums. Exhibitions range from local ancient Roman archeological sites to contemporary graphics, the Cologne Trade Fair hosts a number of trade shows such as Art Cologne, imm Cologne, Gamescom, and the Photokina. The first urban settlement on the grounds of modern-day Cologne was Oppidum Ubiorum, founded in 38 BC by the Ubii, in 50 AD, the Romans founded Colonia on the Rhine and the city became the provincial capital of Germania Inferior in 85 AD. The city was named Colonia Claudia Ara Agrippinensium in 50 AD, considerable Roman remains can be found in present-day Cologne, especially near the wharf area, where a notable discovery of a 1900-year-old Roman boat was made in late 2007. From 260 to 271 Cologne was the capital of the Gallic Empire under Postumus, Marius, in 310 under Constantine a bridge was built over the Rhine at Cologne. Roman imperial governors resided in the city and it one of the most important trade. Cologne is shown on the 4th century Peutinger Map, maternus, who was elected as bishop in 313, was the first known bishop of Cologne. The city was the capital of a Roman province until occupied by the Ripuarian Franks in 462, parts of the original Roman sewers are preserved underneath the city, with the new sewerage system having opened in 1890. Early medieval Cologne was part of Austrasia within the Frankish Empire, Cologne had been the seat of a bishop since the Roman period, under Charlemagne, in 795, bishop Hildebold was promoted to archbishop

North Rhine-Westphalia
–
North Rhine-Westphalia is the most populous state of Germany, with a population of approximately 18 million, and the fourth largest by area. Its capital is Düsseldorf, the most populous city is Cologne, four of Germanys ten largest cities—Cologne, Düsseldorf, Dortmund, and Essen—are located within the state, as well as the largest metropolitan area on the European continent, Rhine-Ruhr. North Rhine-Westphalia was formed in 1946 as a merger of the provinces of North Rhine and Westphalia, the state has been run by a coalition of the Social Democrats and Greens since 2010. The Ubii and some other Germanic tribes such as the Cugerni were later settled on the west side of the Rhine in the Roman province of Germania Inferior, North of the Sigambri and the Rhine region were the Bructeri. By the 8th century the Frankish dominion was established in western Germany. But at the time, to the north, Westphalia was being taken over by Saxons pushing south. The Merovingian and Carolingian Franks eventually built an empire which controlled first their Ripuarian kin, the Ottonian dynasty had both Saxon and Frankish ancestry. As the central power of the Holy Roman Emperor weakened, the Rhineland split into small independent principalities, each with its separate vicissitudes. Such struggles as the War of the Limburg Succession therefore continued to create military, Aachen was the place of coronation of the German emperors, and the ecclesiastical principalities of the Rhine bulked largely in German history. Prussia first set foot on the Rhine in 1609 by the occupation of the Duchy of Cleves and about a century later Upper Guelders and Moers also became Prussian. At the peace of Basel in 1795 the whole of the bank of the Rhine was resigned to France. In 1920, the districts of Eupen and Malmedy were transferred to Belgium, around 1 AD there were numerous incursions through Westphalia and perhaps even some permanent Roman or Romanized settlements. The Battle of Teutoburg Forest took place near Osnabrück and some of the Germanic tribes who fought at this came from the area of Westphalia. Charlemagne is thought to have spent considerable time in Paderborn and nearby parts and his Saxon Wars also partly took place in what is thought of as Westphalia today. Popular legends link his adversary Widukind to places near Detmold, Bielefeld, Lemgo, Osnabrück, Widukind was buried in Enger, which is also a subject of a legend. Along with Eastphalia and Engern, Westphalia was originally a district of the Duchy of Saxony, in 1180 Westphalia was elevated to the rank of a duchy by Emperor Barbarossa. The Duchy of Westphalia comprised only an area south of the Lippe River. Parts of Westphalia came under Brandenburg-Prussian control during the 17th and 18th centuries, the Peace of Westphalia of 1648, signed in Münster and Osnabrück, ended the Thirty Years War

Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of 357,021 square kilometres, with about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular destination in the world. Germanys capital and largest metropolis is Berlin, while its largest conurbation is the Ruhr, other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart, Düsseldorf and Leipzig. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity, a region named Germania was documented before 100 AD. During the Migration Period the Germanic tribes expanded southward, beginning in the 10th century, German territories formed a central part of the Holy Roman Empire. During the 16th century, northern German regions became the centre of the Protestant Reformation, in 1871, Germany became a nation state when most of the German states unified into the Prussian-dominated German Empire. After World War I and the German Revolution of 1918–1919, the Empire was replaced by the parliamentary Weimar Republic, the establishment of the national socialist dictatorship in 1933 led to World War II and the Holocaust. After a period of Allied occupation, two German states were founded, the Federal Republic of Germany and the German Democratic Republic, in 1990, the country was reunified. In the 21st century, Germany is a power and has the worlds fourth-largest economy by nominal GDP. As a global leader in industrial and technological sectors, it is both the worlds third-largest exporter and importer of goods. Germany is a country with a very high standard of living sustained by a skilled. It upholds a social security and universal health system, environmental protection. Germany was a member of the European Economic Community in 1957. It is part of the Schengen Area, and became a co-founder of the Eurozone in 1999, Germany is a member of the United Nations, NATO, the G8, the G20, and the OECD. The national military expenditure is the 9th highest in the world, the English word Germany derives from the Latin Germania, which came into use after Julius Caesar adopted it for the peoples east of the Rhine. This in turn descends from Proto-Germanic *þiudiskaz popular, derived from *þeudō, descended from Proto-Indo-European *tewtéh₂- people, the discovery of the Mauer 1 mandible shows that ancient humans were present in Germany at least 600,000 years ago. The oldest complete hunting weapons found anywhere in the world were discovered in a mine in Schöningen where three 380, 000-year-old wooden javelins were unearthed

Deutsche Bundesbahn
–
The Deutsche Bundesbahn or DB was formed as the state railway of the newly established Federal Republic of Germany on 7 September 1949 as a successor of the Deutsche Reichsbahn-Gesellschaft. After World War II, each of the governments of the Allied Occupation Zones in Germany was de facto in charge of the German railways in their respective territories. With the formation of the FRG these successor organizations of the DRG were reunited, the railways in the Saarland joined on 1 January 1957. The DB was a company that, with few local exceptions. The DB was placed under the control of the Bundesverkehrsministerium, with its headquarters in Frankfurt, in 1985 the DB was the third-largest employer in the FRG, with a strength of 322,383 employees. A special transit police provided security, the immediate tasks in the early years after the end of World War II involved the reconstruction of the heavily damaged infrastructure and the replenishment of locomotives and rolling stock. Contrary to the Deutsche Reichsbahn in the GDR, the DB was not subject to reparations, during the early years, new steam engines were constructed and placed into service. The last new locomotive type was the Class 10, which entered service in 1957. Only two units of class 10 were built, in 1959 DB took the last steam locomotive delivery when the last of the class 23 locomotives was delivered. Soon, with increase in mass motorization, the railway started to lose passenger volume, as a result, rail buses were introduced on some lines, while other smaller volume lines were closed. The later years of this saw a decrease and eventual phasing out of steam engines. Traction was provided increasingly by diesel and electric engines, with increased use of diesel and electric locomotives, progress was made in decreasing travel time for passengers. New types of trains were introduced such as the Trans Europ Express. Transport of goods also had to compete with the competition from trucks. Furthermore, traditional services such as coal and iron ore shipments declined with the changes in the overall economy, after the introduction of the TGV in France, the ICE system of high speed passenger trains was developed. Significant stretches of new high speed track, like the Hanover-Würzburg high-speed rail line, had to be laid or upgraded, other characteristics of this epoch are the introduction of computer systems and the steps taken towards an integrated system of European railways. Externally, rolling stock displayed more colourful and varied livery schemes, the two German states were reunified in October 1990 with both DB and DR now being special funds of the German Federal government. Article 26 of the Unification Treaty stipulated the DR to be merged with DB at the earliest opportunity

Therefore, the design is often called a bowstring-arch or bowstring-girder bridge. In addition, since they do not depend on horizontal compression forces for their integrity, tied-arch bridges can be prefabricated offsite, and subsequently floated, hauled or lifted into place. Notable bridges of this include the Fremont Bridge in Portland, Oregon as well as the first computer designed bridge of this type the Fort Pitt Bridge in Pittsburgh. A bowstring truss bridge is similar in appearance to a tied-arch, however, the visual distinction is a tied-arch bridge will not have substantial diagonal members between the vertical members. Both the tied-arch bridge and the suspension bridge place only vertical loads on the anchorage. In addition, problems with electroslag welds, while not isolated to tied-arch bridges, resulted in costly, the structure as a whole was described as nonredundant, failure of either of the two tie girders would result in failure of the entire structure

Concrete
–
Concrete is a composite material composed of coarse aggregate bonded together with a fluid cement that hardens over time. Most concretes used are lime-based concretes such as Portland cement concrete or concretes made with other hydraulic cements, when aggregate is mixed together with dry Portland cement and water, the mixture forms a fluid slurry that is easily poured and molded into shape. The cement reacts chemically with the water and other ingredients to form a matrix that binds the materials together into a durable stone-like material that has many uses. Often, additives are included in the mixture to improve the properties of the wet mix or the finished material. Most concrete is poured with reinforcing materials embedded to provide tensile strength, famous concrete structures include the Hoover Dam, the Panama Canal, and the Roman Pantheon. The earliest large-scale users of technology were the ancient Romans. The Colosseum in Rome was built largely of concrete, and the dome of the Pantheon is the worlds largest unreinforced concrete dome. Today, large concrete structures are made with reinforced concrete. After the Roman Empire collapsed, use of concrete became rare until the technology was redeveloped in the mid-18th century, today, concrete is the most widely used man-made material. The word concrete comes from the Latin word concretus, the passive participle of concrescere, from con-. Perhaps the earliest known occurrence of cement was twelve years ago. A deposit of cement was formed after an occurrence of oil shale located adjacent to a bed of limestone burned due to natural causes and these ancient deposits were investigated in the 1960s and 1970s. On a human timescale, small usages of concrete go back for thousands of years and they discovered the advantages of hydraulic lime, with some self-cementing properties, by 700 BC. They built kilns to supply mortar for the construction of houses, concrete floors. The cisterns were kept secret and were one of the reasons the Nabataea were able to thrive in the desert, some of these structures survive to this day. In the Ancient Egyptian and later Roman eras, it was re-discovered that adding volcanic ash to the mix allowed it to set underwater, similarly, the Romans knew that adding horse hair made concrete less liable to crack while it hardened, and adding blood made it more frost-resistant. Crystallization of strätlingite and the introduction of pyroclastic clays creates further fracture resistance, german archaeologist Heinrich Schliemann found concrete floors, which were made of lime and pebbles, in the royal palace of Tiryns, Greece, which dates roughly to 1400–1200 BC. Lime mortars were used in Greece, Crete, and Cyprus in 800 BC, the Assyrian Jerwan Aqueduct made use of waterproof concrete

Steel
–
Steel is an alloy of iron and other elements, primarily carbon, that is widely used in construction and other applications because of its high tensile strength and low cost. Steels base metal is iron, which is able to take on two forms, body centered cubic and face centered cubic, depending on its temperature. It is the interaction of those allotropes with the elements, primarily carbon. In the body-centred cubic arrangement, there is an atom in the centre of each cube. Carbon, other elements, and inclusions within iron act as hardening agents that prevent the movement of dislocations that otherwise occur in the lattices of iron atoms. The carbon in steel alloys may contribute up to 2. 1% of its weight. Steels strength compared to pure iron is possible at the expense of irons ductility. With the invention of the Bessemer process in the mid-19th century and this was followed by Siemens-Martin process and then Gilchrist-Thomas process that refined the quality of steel. With their introductions, mild steel replaced wrought iron, further refinements in the process, such as basic oxygen steelmaking, largely replaced earlier methods by further lowering the cost of production and increasing the quality of the product. Today, steel is one of the most common materials in the world and it is a major component in buildings, infrastructure, tools, ships, automobiles, machines, appliances, and weapons. Modern steel is generally identified by various grades defined by assorted standards organizations, the noun steel originates from the Proto-Germanic adjective stakhlijan, which is related to stakhla. The carbon content of steel is between 0. 002% and 2. 1% by weight for plain iron–carbon alloys and these values vary depending on alloying elements such as manganese, chromium, nickel, iron, tungsten, carbon and so on. Basically, steel is an alloy that does not undergo eutectic reaction. In contrast, cast iron does undergo eutectic reaction, too little carbon content leaves iron quite soft, ductile, and weak. Carbon contents higher than those of steel make an alloy, commonly called pig iron, while iron alloyed with carbon is called carbon steel, alloy steel is steel to which other alloying elements have been intentionally added to modify the characteristics of steel. Common alloying elements include, manganese, nickel, chromium, molybdenum, boron, titanium, vanadium, tungsten, cobalt, and niobium. Additional elements are important in steel, phosphorus, sulfur, silicon, and traces of oxygen, nitrogen, and copper. Alloys with a higher than 2. 1% carbon content, depending on other element content, cast iron is not malleable even when hot, but it can be formed by casting as it has a lower melting point than steel and good castability properties

Superstructure
–
A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of structures such as buildings, bridges. The word superstructure is a combination of the Latin prefix, super with the Latin stem word, in order to improve the response during earthquakes of buildings and bridges, the superstructure might be separated from its foundation by various civil engineering mechanisms or machinery. All together, these implement the system of protection called base isolation. As stated above, superstructure consists of the parts of the ship or a boat, including sailboats, fishing boats, passenger ships, and submarines and this does not usually include its masts or any armament turrets. Note that in times, turrets do not always carry naval artillery. The size of a watercrafts superstructure can have implications in the performance of ships and boats, since these structures can alter their structural rigidity, their displacements. These can be detrimental to any vessels performance if they are taken into consideration incorrectly, the height and the weight of superstructure on board a ship or a boat also affects the amount of freeboard that such a vessel requires along its sides, down to her waterline. In broad terms, the more and heavier superstructure that a ship possesses, on a bridge, the portion of the structure that is the span and directly receives the live load is referred to as the superstructure. In contrast, the abutment, piers, and other structures are called the substructure

Krupp
–
The Krupp family, a prominent 400-year-old German dynasty from Essen, have become famous for their production of steel, artillery, ammunition, and other armaments. The family business, known as Friedrich Krupp AG, was the largest company in Europe at the beginning of the 20th century and it was important to weapons development and production in both world wars. One of the most powerful dynasties in European history, for 400 years Krupp flourished as the premier weapons manufacturer for Germany. From the Thirty Years War until the end of the Second World War, they produced everything from battleships, U-boats, tanks, howitzers, guns, utilities, the dynasty began in 1587 when a trader named Arndt Krupp moved to Essen and joined the merchants guild. He then began buying vacated real estate from families who fled the city due to the Black Death, over the next three centuries his descendants began producing small guns during the Thirty Years War and over time gradually acquired fulling mills, coal mines, and an iron forge. During the Napoleonic Wars, Friedrich Krupp founded the Gusstahlfabrik and began producing smelted steel in 1816, the foundations were laid for the steel Empire that would come to dominate the world for nearly a century under his son Alfred. Krupp became the manufacturer for the Kingdom of Prussia in 1859. Krupp was also a company that paved the way for workers rights. Widows and orphans were guaranteed pay if their husbands and/or fathers were killed, the company also produced the steel that built the railroads of America, capped the Chrysler Building in 1929, and was the first to travel to the bottom of the Mariana Trench. During the Third Reich, Krupp supported Adolf Hitler and the use of forced labour, after the war Krupp was rebuilt from scratch and again became one of the wealthiest companies in Europe. However a recession in 1967 caused the company severe profit loss, in 1999 the Krupp firm merged with Thyssen AG to form ThyssenKrupp AG, a large industrial conglomerate. Friedrich Krupp launched the familys metal-based activities, building a steel foundry in Essen in 1810. His son Alfred, known as the Cannon King or as Alfred the Great, invested heavily in new technology to become a significant manufacturer of steel rollers and he also invested in fluidized hotbed technologies and acquired many mines in Germany and France. Unusual for the era, he provided social services for his workers, including subsidized housing and health, the company began to make steel cannons in the 1840s—especially for the Russian, Turkish, and Prussian armies. When Alfred started with the firm, it had five employees, at his death twenty thousand people worked for Krupp—making it the worlds largest industrial company and the largest private company in the German empire. Krupps had a Great Krupp Building with an exhibition of guns at the Columbian Exposition in 1893, in the 20th century the company was headed by Gustav Krupp von Bohlen und Halbach, who assumed the surname of Krupp when he married the Krupp heiress, Bertha Krupp. After Adolf Hitler came to power in Germany in 1933, the Krupp works became the center for German rearmament. In 1943, by an order from Hitler, the company reverted to a sole-proprietorship, with Gustav

Thyssen AG
–
Thyssen was a major German steel producer founded by August Thyssen. After over 100 years of existence, the merged with Friedrich Krupp AG Hoesch-Krupp to form ThyssenKrupp in 1999. On 29 September 1891 August Thyssen and his brother Joseph came to be in possession of all shares of Gewerkschaft Deutscher Kaiser, on 17 December 1891 the steelworks of the same company opened in Hamborn, Duisburg. Subsequently, the plant was modernized and expanded by August Thyssen, becoming an integrated company producing iron and steel and manufacturing ships. After the First World War came the occupation of the Ruhr, in 1934, August Thyssen-Hütte AG was founded as part of the new group. The Nazi rearmament policy and subsequent war made the plants essential to the war economy, after the end of World War II, the Allies ordered the company to be liquidated and in 1953 a new company, also named August Thyssen-Hütte AG, was formed in Duisburg. The other mills of the company in Duisburg became legally independent entities, however, the mining division was not reconglomerated, thus Thyssen became largely a steel company. In 1954/55, the focused on acquisitions to restore the vertical integration by acquiring mining concerns. Further companies were acquired, Niederrheinischen Hütte AG in 1956, Deutschen Edelstahlwerke AG in 1957, Phoenix-Rheinrohr AG, the product range included steel sections and flat steel in all grades, including high-alloy steel. By the mid 1960s, August Thyssen-Hütte AG was Europes largest crude steel producer, in the 1960s, the company also formed cooperative alliances with companies such as Mannesmann AG. By 1972, it employed 92,200 people and generated sales of 9.8 billion DM. In 1973, the company acquired Rheinstahl AG, which was mainly a manufacturing company and this takeover reduced the companys dominance in the steel industry and converted it to a conglomerate. In 1977, the company became Thyssen AG, with Rheinstahl AG already having been renamed Thyssen Industrie AG in 1976, in 1983, Thyssen Stahl AG was spun off. During the 1980s, talks on a merger between Thyssen Stahl AG and Krupp Stahl AG took place, an alliance did not take place at that time, but there began cooperation on certain business areas. In 1997, the steel production divisions of both groups were merged to form Thyssen Krupp Stahl AG. On 17 March 1999, a new group formed by the merger of Thyssen and Krupp was registered, history - Group - ThyssenKrupp AG. Die Feuer verlöschen nie - August Thyssen-Hütte 1890-1926

Deutsche Mark
–
The Deutsche Mark, abbreviated DM or D-Mark, was the official currency of West Germany and unified Germany until the adoption of the euro in 2002. In English, but not in German, it is called the Deutschmark. Mark coins and banknotes continued to be accepted as valid forms of payment in Germany until 28 February 2002. However, in 2012, it was estimated that as many as 13.2 billion marks were in circulation, with polls showing a narrow majority of Germans favouring the currencys restoration. The Deutsche Bundesbank has guaranteed that all German marks in form may be changed into euros indefinitely. Banknotes and coins can even be sent to the Bundesbank by mail, on 31 December 1998, the Council of the European Union fixed the irrevocable exchange rate, effective 1 January 1999, for German mark to euros as DM1.95583 = €1. One Deutsche Mark was divided into 100 Pfennig, a mark had been the currency of Germany since its original unification in 1871. Before that time, the different German states issued a variety of different currencies, though most were linked to the Vereinsthaler, a silver coin containing 16 2⁄3 grams of pure silver. Although the mark was based on rather than silver, a fixed exchange rate between the Vereinsthaler and the mark of 3 marks =1 Vereinsthaler was used for the conversion. The first mark, known as the Goldmark, was introduced in 1873, with the outbreak of World War I, the mark was taken off the gold standard. The currency thus became known as the Papiermark, especially as inflation, then hyperinflation occurred. The Papiermark was replaced by the Rentenmark from November 15,1923, due to the strains between the Allies each zone was governed independently as regards monetary matters. The US occupation policy was governed by the directive JCS1067, as a consequence a separate monetary reform in the U. S. zone was not possible. Each of the Allies printed its own occupation currency, the Deutsche Mark was officially introduced on Sunday, June 20,1948 by Ludwig Erhard. Large amounts were exchanged for RM10 to 65 Pfennig, in addition, each person received a per capita allowance of DM60 in two parts, the first being DM40 and the second DM20. A few weeks later Erhard, acting against orders, issued an edict abolishing many economic controls which had been implemented by the Nazis. He did this, as he confessed, on Sunday because the offices of the American, British. He was sure if he had done it when they were open

Cologne Cathedral
–
Cologne Cathedral is a Roman Catholic cathedral in Cologne, Germany. It is the seat of the Archbishop of Cologne and of the administration of the Archdiocese of Cologne and it is a renowned monument of German Catholicism and Gothic architecture and was declared a World Heritage Site in 1996. It is Germanys most visited landmark, attracting an average of 20,000 people a day, construction of Cologne Cathedral commenced in 1248 and was halted in 1473, leaving it unfinished. Work restarted in the 19th century and was completed, to the original plan, the cathedral is the largest Gothic church in Northern Europe and has the second-tallest spires. The towers for its two huge spires give the cathedral the largest façade of any church in the world, the choir has the largest height to width ratio,3.6,1, of any medieval church. Colognes medieval builders had planned a structure to house the reliquary of the Three Kings. When construction began on the present Cologne Cathedral in 1248, the site had already occupied by several previous structures. The earliest may have been for storage, and possibly was succeeded by a Roman temple built by Mercurius Augustus. A free-standing baptistery dating the 6th century was located at the east end of the present cathedral, only ruins of the baptistery and the octagonal baptismal font remain today. The second church, called the Old Cathedral, was completed in 818 and it was destroyed by fire on 30 April 1248, during demolition work to prepare for a new cathedral. The relics have great significance and drew pilgrims from all over Christendom. It was important to church officials that they be properly housed, the foundation stone was laid on 15 August 1248, by Archbishop Konrad von Hochstaden. The eastern arm was completed under the direction of Master Gerhard, was consecrated in 1322, eighty four misericords in the choir date from this building phase. In the mid 14th century work on the west front commenced under Master Michael and this work halted in 1473, leaving the south tower complete up to the belfry level and crowned with a huge crane that remained in place as a landmark of the Cologne skyline for 400 years. Some work proceeded intermittently on the structure of the nave between the west front and the arm, but during the 16th century this ceased. It was achieved by effort, the Central-Dombauverein, founded in 1842, raised two-thirds of the enormous costs. The state saw this as a way to improve its relations with the number of Catholic subjects it had gained in 1815. Work resumed in 1842 to the design of the surviving medieval plans and drawings

Museum Ludwig, located in Cologne, Germany, houses a collection of modern art. It includes works from Pop Art, Abstract and Surrealism, and has one of the largest Picasso collections in Europe and it also features many works by Andy Warhol and Roy Lichtenstein. Since November 2012 the museums director has been Philipp Kaiser, the museum emerged in 1976 as an independent institution from the Wallraf-Richartz Museum. The recent building, which was designed by architects Peter Busmann, the new building first became home to both the Wallraf Richartz Museum as well as Museum Ludwig. In 1994, it was decided to separate the two institutions and to place the building on Bischofsgartenstrasse at the disposal of Museum Ludwig. In 1999 Steve Keene painted in the museum, the building is also home to the Kölner Philharmonic. The Heinrich-Böll-Platz, a public square designed by Dani Karavan, is above the hall at the north-east of the building. Unfortunately, during concerts people cant walk upon the square as it creates acoustic disturbances for the concert goers below. The museum essentially incorporates the Sammlung Haubrich, a collection by lawyer Josef Haubrich of art from the years 1914 to 1939 donated to the city of Cologne on 2 May 1946. Directly after World War II, in May 1946, Haubrich presented the city with his Expressionism collection, the second integral part of the museum is the Sammlung Ludwig, a collection of art by Picasso, Russian avant-garde and American Pop-art artists. With around 900 works by Picasso, the museum today has the third largest collection of this artist worldwide, after Barcelona, today the museum houses the most comprehensive collection of early Russian avant-garde artworks outside Russia.

Cathedral Bridge
–
The Cathedral Bridge was a railway and street bridge crossing the river Rhine in the German city of Cologne. It was owned by the Cologne-Minden Railway Company and named after the Cologne Cathedral and it was built in combination with the original Central Station and a new ground-level railway track through the north Altstadt of the Cologne Innenstadt. As the Cathedral Bridge could not bolster the increased traffic of the new Köln Hauptbahnhof in 1894, the Prussian authorities pressed for a bridge due to increasing road traffic between Cologne and the eastern river bank. Before the Cathedral Bridge, passengers and goods had to be transported across the river by ferry or pontoon bridge. The initial drawings of the bridge allowed only one carriage to cross the bridge. On the western bank, the road was led in northeastern direction past the Cologne Cathedral.9 metres, conversely, the Cathedral Bridge was a lattice truss bridge with spans up to 103.2 metres and a collective width of 16.73 metres. Designed by Robert Stephenson as a bridge, the longest spans of the Britannia Bridge measured 140 metres. The combination of a structure that could be closed on either side inspired the local nickname mouse trap. The bridge was referred to as solid bridge, because it was the first immovable bridge in between Basel and the Netherlands since the Roman bridge, built near Cologne in the 4th century. Since the Middle Ages, reaction ferries formed flying bridges and since Prussian times, ships bridges, the earthworks started on 6 June 1855, the foundation stone was laid by Frederick William IV four months later, on 3 October. Only after construction work had begun were the designs altered to include dual railway tracks on the downstream side of the bridge. Since the early 1850s, the Prussian authorities emphasized on constructing state railways. At the request of the Prussian Army, who had to approve every bridge design before it was carried out, it included a swing bridge on the western side which could be closed in case of war. The design was inspired by the bridges over the river Vistula at Tczew and over the river Nogat at Malbork. The same chief superintendent for those bridges, Hermann Lohse, also led the work for the Cathedral Bridge. The Cathedral Bridge was inaugurated on 3 October 1859, exactly four years construction work had officially begun. Forty years after the construction, it was estimated the bridge had cost nearly 4 million Thalers, the bridge was unable to meet the increased requirements imposed on it by the new Cologne Central Station. After the construction work had started for the Hohenzollern Bridge in 1907

Arch bridge
–
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side, a viaduct may be made from a series of arches, although other more economical structures are typically used today. Possibly the oldest existing bridge is the Mycenaean Arkadiko bridge in Greece from about 1300 BC. The stone corbel arch bridge is used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch, a more complete survey by the Italian scholar Vittorio Galliazzo found 931 Roman bridges, mostly of stone, in as many as 26 different countries. Roman arch bridges were usually semicircular, although a number were segmental arch bridges, generally, Roman bridges featured wedge-shaped primary arch stones of the same in size and shape. The Romans built both single spans and lengthy multiple arch aqueducts, such as the Pont du Gard and Segovia Aqueduct. Their bridges featured from an early time onwards flood openings in the piers, e. g. in the Pons Fabricius in Rome, Roman engineers were the first and until the industrial revolution the only ones to construct bridges with concrete, which they called Opus caementicium. The outside was covered with brick or ashlar, as in the Alcántara bridge. The Romans also introduced segmental arch bridges into bridge construction, trajans bridge over the Danube featured open-spandrel segmental arches made of wood. This was to be the longest arch bridge for a thousand years both in terms of overall and individual span length, while the longest extant Roman bridge is the 790 m long Puente Romano at Mérida. The late Roman Karamagara Bridge in Cappadocia may represent the earliest surviving bridge featuring a pointed arch, in medieval Europe, bridge builders improved on the Roman structures by using narrower piers, thinner arch barrels and lower span-rise ratios on bridges. Gothic pointed arches were introduced, reducing lateral thrust. The 14th century in particular saw bridge building reaching new heights, the bridge at Trezzo sullAdda, destroyed in the 15th century, even featured a span length of 72 m, not matched until 1796. Constructions such as the acclaimed Florentine segmental arch bridge Ponte Vecchio combined sound engineering with aesthetical appeal, the three elegant arches of the Renaissance Ponte Santa Trinita constitute the oldest elliptic arch bridge worldwide. In China, the oldest existing bridge is the Zhaozhou Bridge of 605 AD. The Zhaozhou Bridge, with a length of 167 feet and span of 123 feet, is the worlds first wholly stone open-spandrel segmental arch bridge, Bridges with perforated spandrels can be found worldwide, such as in China

German language
–
German is a West Germanic language that is mainly spoken in Central Europe. It is the most widely spoken and official language in Germany, Austria, Switzerland, South Tyrol, the German-speaking Community of Belgium and it is also one of the three official languages of Luxembourg. Major languages which are most similar to German include other members of the West Germanic language branch, such as Afrikaans, Dutch, English, Luxembourgish and it is the second most widely spoken Germanic language, after English. One of the languages of the world, German is the first language of about 95 million people worldwide. The German speaking countries are ranked fifth in terms of publication of new books. German derives most of its vocabulary from the Germanic branch of the Indo-European language family, a portion of German words are derived from Latin and Greek, and fewer are borrowed from French and English. With slightly different standardized variants, German is a pluricentric language, like English, German is also notable for its broad spectrum of dialects, with many unique varieties existing in Europe and also other parts of the world. The history of the German language begins with the High German consonant shift during the migration period, when Martin Luther translated the Bible, he based his translation primarily on the standard bureaucratic language used in Saxony, also known as Meißner Deutsch. Copies of Luthers Bible featured a long list of glosses for each region that translated words which were unknown in the region into the regional dialect. Roman Catholics initially rejected Luthers translation, and tried to create their own Catholic standard of the German language – the difference in relation to Protestant German was minimal. It was not until the middle of the 18th century that a widely accepted standard was created, until about 1800, standard German was mainly a written language, in urban northern Germany, the local Low German dialects were spoken. Standard German, which was different, was often learned as a foreign language with uncertain pronunciation. Northern German pronunciation was considered the standard in prescriptive pronunciation guides though, however, German was the language of commerce and government in the Habsburg Empire, which encompassed a large area of Central and Eastern Europe. Until the mid-19th century, it was essentially the language of townspeople throughout most of the Empire and its use indicated that the speaker was a merchant or someone from an urban area, regardless of nationality. Some cities, such as Prague and Budapest, were gradually Germanized in the years after their incorporation into the Habsburg domain, others, such as Pozsony, were originally settled during the Habsburg period, and were primarily German at that time. Prague, Budapest and Bratislava as well as cities like Zagreb, the most comprehensive guide to the vocabulary of the German language is found within the Deutsches Wörterbuch. This dictionary was created by the Brothers Grimm and is composed of 16 parts which were issued between 1852 and 1860, in 1872, grammatical and orthographic rules first appeared in the Duden Handbook. In 1901, the 2nd Orthographical Conference ended with a standardization of the German language in its written form

Bridge
–
A bridge is a structure built to span physical obstacles without closing the way underneath such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. There are many different designs that each serve a particular purpose, the Oxford English Dictionary traces the origin of the word bridge to an Old English word brycg, of the same meaning. The word can be traced back to Proto-Indo-European *bʰrēw-. The word for the game of the same name has a different origin. The first bridges made by humans were probably spans of cut wooden logs or planks and eventually stones, using a simple support, some early Americans used trees or bamboo poles to cross small caverns or wells to get from one place to another. Dating to the Greek Bronze Age, it is one of the oldest arch bridges still in existence, several intact arched stone bridges from the Hellenistic era can be found in the Peloponnese. The greatest bridge builders of antiquity were the ancient Romans, the Romans built arch bridges and aqueducts that could stand in conditions that would damage or destroy earlier designs. An example is the Alcántara Bridge, built over the river Tagus, the Romans also used cement, which reduced the variation of strength found in natural stone. One type of cement, called pozzolana, consisted of water, lime, sand, brick and mortar bridges were built after the Roman era, as the technology for cement was lost. In India, the Arthashastra treatise by Kautilya mentions the construction of dams, a Mauryan bridge near Girnar was surveyed by James Princep. The bridge was swept away during a flood, and later repaired by Puspagupta, the use of stronger bridges using plaited bamboo and iron chain was visible in India by about the 4th century. A number of bridges, both for military and commercial purposes, were constructed by the Mughal administration in India and this bridge is also historically significant as it is the worlds oldest open-spandrel stone segmental arch bridge. European segmental arch bridges date back to at least the Alconétar Bridge, rope bridges, a simple type of suspension bridge, were used by the Inca civilization in the Andes mountains of South America, just prior to European colonization in the 16th century. During the 18th century there were innovations in the design of timber bridges by Hans Ulrich Grubenmann, Johannes Grubenmann. The first book on bridge engineering was written by Hubert Gautier in 1716, a major breakthrough in bridge technology came with the erection of the Iron Bridge in Shropshire, England in 1779. It used cast iron for the first time as arches to cross the river Severn, with the Industrial Revolution in the 19th century, truss systems of wrought iron were developed for larger bridges, but iron does not have the tensile strength to support large loads. With the advent of steel, which has a tensile strength, much larger bridges were built. In 1927 welding pioneer Stefan Bryła designed the first welded bridge in the world

Railway
–
Rail transport is a means of conveyance of passengers and goods on wheeled vehicles running on rails, also known as tracks. It is also referred to as train transport. In contrast to road transport, where vehicles run on a flat surface. Tracks usually consist of rails, installed on ties and ballast, on which the rolling stock, usually fitted with metal wheels. Other variations are possible, such as slab track, where the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a transport system generally encounters lower frictional resistance than road vehicles, so passenger. The operation is carried out by a company, providing transport between train stations or freight customer facilities. Power is provided by locomotives which either draw electric power from a railway system or produce their own power. Most tracks are accompanied by a signalling system, Railways are a safe land transport system when compared to other forms of transport. The oldest, man-hauled railways date back to the 6th century BC, with Periander, one of the Seven Sages of Greece, Rail transport blossomed after the British development of the steam locomotive as a viable source of power in the 19th centuries. With steam engines, one could construct mainline railways, which were a key component of the Industrial Revolution, also, railways reduced the costs of shipping, and allowed for fewer lost goods, compared with water transport, which faced occasional sinking of ships. The change from canals to railways allowed for markets in which prices varied very little from city to city. In the 1880s, electrified trains were introduced, and also the first tramways, starting during the 1940s, the non-electrified railways in most countries had their steam locomotives replaced by diesel-electric locomotives, with the process being almost complete by 2000. During the 1960s, electrified high-speed railway systems were introduced in Japan, other forms of guided ground transport outside the traditional railway definitions, such as monorail or maglev, have been tried but have seen limited use. The history of the growth, decline and restoration to use of transport can be divided up into several discrete periods defined by the principal means of motive power used. The earliest evidence of a railway was a 6-kilometre Diolkos wagonway, trucks pushed by slaves ran in grooves in limestone, which provided the track element. The Diolkos operated for over 600 years, Railways began reappearing in Europe after the Dark Ages. The earliest known record of a railway in Europe from this period is a window in the Minster of Freiburg im Breisgau in Germany

House of Hohenzollern
–
The House of Hohenzollern is a dynasty of former princes, electors, kings and emperors of Hohenzollern, Brandenburg, Prussia, the German Empire, and Romania. The family arose in the area around the town of Hechingen in Swabia during the 11th century, the first ancestor of the Hohenzollerns was mentioned in 1061. They may have derived from the Burchardinger dynasty, the Hohenzollern family split into two branches, the Catholic Swabian branch and the Protestant Franconian branch, which later became the Brandenburg-Prussian branch. The Swabian branch ruled the principalities of Hohenzollern-Hechingen and Hohenzollern-Sigmaringen until 1849, members of the Franconian branch became Margrave of Brandenburg in 1415 and Duke of Prussia in 1525. The Margraviate of Brandenburg and the Duchy of Prussia were ruled in personal union after 1618 and were called Brandenburg-Prussia, germanys defeat in World War I in 1918 led to the German Revolution. The Hohenzollerns were overthrown and the Weimar Republic was established, thus bringing an end to the German monarchy, Georg Friedrich, Prince of Prussia is the current head of the royal Prussian line, while Karl Friedrich, Prince of Hohenzollern is the head of the princely Swabian line. Zollern, from 1218 Hohenzollern, was a county of the Holy Roman Empire and its ruling dynasty was first mentioned in 1061. The Hohenzollerns named their estates after Hohenzollern Castle in the Swabian Alps, the Hohenzollern Castle still belongs to the family today. According to the medieval chronicler Berthold of Reichenau, Burkhard I, Count of Zollern was born before 1025, the Zollerns received the comital title from Emperor Henry V in 1111. As loyal vassals of the Swabian Hohenstaufen dynasty, they were able to enlarge their territory. In 1218 the burgraviate passed to Fredericks younger son Conrad I, he became the ancestor of the Franconian Hohenzollern branch. 1150-1155 and 1160, Gotfried of Zimmern, 4th oldest son of Frederick I before 1171 – c,1200, Frederick III/I Count Frederick III of Zollern was a loyal retainer of the Holy Roman Emperors Frederick Barbarossa and Henry VI. In about 1185 he married Sophia of Raabs, the daughter of Conrad II, after the death of Conrad II who left no male heirs, Frederick III was granted Nuremberg in 1192 as Burgrave Frederick I of Nuremberg-Zollern. Since then the name has been Hohenzollern. The younger brother, Conrad III, received the burgraviate of Nuremberg from his older brother Frederick IV in 1218, members of the Franconian line eventually became the Brandenburg-Prussian branch. The Franconian line later converted to Protestantism, the cadet Franconian branch of the House of Hohenzollern was founded by Conrad I, Burgrave of Nuremberg. Beginning in the 16th century, this branch of the family became Protestant and decided on expansion through marriage, the family supported the Hohenstaufen and Habsburg rulers of the Holy Roman Empire during the 12th to 15th centuries, being rewarded with several territorial grants. He ruled the Margraviate of Brandenburg-Ansbach after 1398, from 1420, he became Margrave of Brandenburg-Kulmbach

Rhine Province
–
It was created from the provinces of the Lower Rhine and Jülich-Cleves-Berg. Its capital was Koblenz and in 1939 it had 8 million inhabitants, the Province of Hohenzollern was militarily associated with the Oberpräsident of the Rhine Province. The small exclave district of Wetzlar, wedged between the grand duchy states Hesse-Nassau and Hesse-Darmstadt was also part of the Rhine Province, the principality of Birkenfeld, on the other hand, was an enclave of the Grand Duchy of Oldenburg, a separate state of the German Empire. In 1911, the extent of the province was 10,423 km2, its length, from north to south, was nearly 200 km. The population of the Rhine Province in 1905 was 6,435,778, the left bank was predominately Catholic, while on the right bank about half the population was Protestant. The great bulk of the population was ethnically German, although some villages, on the western and southern frontiers resided smaller French-speaking communities, while the industrial region of the Ruhr housed recent Polish migrants from the eastern provinces of the Empire. The Rhine Province was the most densely populated part of Prussia, the province contains a greater number of large towns than any other province in Prussia. Upwards of half the population were supported by industrial and commercial pursuits, there was the University of Bonn, and elementary education was especially successful. For purposes of administration the province was divided into the five districts of Koblenz, Düsseldorf, Cologne, Aachen, Koblenz was the official capital, though Cologne was the largest and most important city. Being a frontier province, the Rhineland was strongly garrisoned, the province sent 35 members to the German Reichstag and 62 to the Prussian House of Representatives. Of the total area of the Rhine Province about 45% was occupied by land, 16% by meadows and pastures. Little except oats and potatoes could be raised on the plateaus in the south of the province, but the river-valleys. The great bulk of the soil was in the hands of small proprietors, the usual cereal crops were, however, all grown with success, and tobacco, hops, flax, hemp and beetroot were cultivated for commercial purposes. Large quantities of fruit were also produced, the vine-culture occupied a space of about 30,000 acres, about half of which was in the valley of the Mosel, a third in that of the Rhine itself, and the rest mainly on the Nahe and the Ahr. In the hilly districts more than half the surface was occupied by forests. Considerable herds of cattle were reared on the pastures of the lower Rhine. The wooded hills were well stocked with deer, and a stray wolf occasionally found its way from the forests of the Ardennes into those of the Hunsrück, the salmon fishery of the Rhine was very productive, and trout abound in the mountain streams. The great mineral wealth of the Rhine Province furnished its most substantial claim to the title of the richest jewel in the crown of Prussia, besides parts of the carboniferous measures of the Saar and the Ruhr, it also contains important deposits of coal near Aachen

Wilhelm II
–
Wilhelm II or William II was the last German Emperor and King of Prussia, ruling the German Empire and the Kingdom of Prussia from 15 June 1888 to 9 November 1918. He was the eldest grandchild of the British Queen Victoria and related to many monarchs and his leading generals, Paul von Hindenburg and Erich Ludendorff, dictated policy during the First World War with little regard for the civilian government. An ineffective war-time leader, he lost the support of the army, abdicated in November 1918, and fled to exile in the Netherlands. Wilhelm was born on 27 January 1859 at the Crown Princes Palace, Berlin to Prince Frederick William of Prussia and his wife, Victoria, Princess Royal, the eldest daughter of Britains Queen Victoria. At the time of his birth, his great-uncle Frederick William IV was king of Prussia, a traumatic breech birth left him with a withered left arm due to Erbs palsy, which he tried with some success to conceal. His left arm was about 6 inches shorter than his right arm, historians have suggested that this disability affected his emotional development. In 1863, Wilhelm was taken to England to be present at the wedding of his Uncle Bertie, William attended the ceremony in a Highland costume, complete with a small toy dirk. During the ceremony the four-year-old became restless and his eighteen-year-old uncle Alfred, Duke of Edinburgh, charged with keeping an eye on him, told him to be quiet, but Wilhelm drew his dirk and threatened Alfred. When Alfred attempted to subdue him by force, Wilhelm bit him on the leg and his grandmother, Queen Victoria, missed seeing the fracas, to her Wilhelm remained a clever, dear, good little child, the great favourite of my beloved Vicky. His mother, Vicky, was obsessed with his damaged arm and she blamed herself for the childs handicap and insisted that he become a good rider. The thought that he, as heir to the throne, should not be able to ride was intolerable to her, riding lessons began when Wilhelm was eight and were a matter of endurance for Wilhelm. Over and over, the prince was set on his horse. He fell off time after time but despite his tears was set on its back again, after weeks of this he finally got it right and was able to maintain his balance. Wilhelm, from six years of age, was tutored and heavily influenced by the 39-year-old teacher Georg Hinzpeter, Hinzpeter, he later wrote, was really a good fellow. Whether he was the tutor for me, I dare not decide. The torments inflicted on me, in this riding, must be attributed to my mother. As a teenager he was educated at Kassel at the Friedrichsgymnasium, in January 1877, Wilhelm finished high school and on his eighteenth birthday received as a present from his grandmother, Queen Victoria, the Order of the Garter. After Kassel he spent four terms at the University of Bonn, studying law and he became a member of the exclusive Corps Borussia Bonn

Friedrich Wilhelm IV
–
Frederick William IV, the eldest son and successor of Frederick William III of Prussia, reigned as King of Prussia from 1840 to 1861. In politics, he was a conservative, and in 1849 rejected the title of Emperor of the Germans offered by the Frankfurt Parliament as not the Parliaments to give, in 1857, he suffered a stroke and was left incapacitated until his death. Born to Frederick William III by his wife Queen Louise, he was the favourite son. Frederick William was educated by tutors, many of whom were experienced civil servants. He also gained experience by serving in the Prussian Army during the War of Liberation against Napoleon in 1814. In 1823 he married Elisabeth Ludovika of Bavaria, since she was a Roman Catholic, the preparations for this marriage included difficult negotiations which ended with her conversion to Lutheranism. There were two wedding ceremonies—one in Munich, and another in Berlin, the couple had a very harmonious marriage, but childless. Frederick William opposed the idea of a unified German state, believing that Austria was divinely ordained to rule over Germany, Frederick William became King of Prussia on the death of his father in 1840. Through a personal union, he became the sovereign prince of the Principality of Neuchâtel. In 1842, he gave his fathers menagerie at Pfaueninsel to the new Berlin Zoo, despite being a devout Lutheran, his Romantic leanings led him to settle the Cologne church conflict by releasing the imprisoned Clemens August von Droste-Vischering, the Archbishop of Cologne. He also patronized further construction of Cologne Cathedral, Cologne having become part of Prussia in 1815, in 1844, he attended the celebrations marking the completion of the cathedral, becoming the first king of Prussia to enter a Roman Catholic building. He committed himself to German unification, formed a government, convened a national assembly. Once his position was more secure again, however, he quickly had the army reoccupy Berlin and in December dissolved the assembly, therefore, Frederick William would only accept the imperial crown after being elected by the German princes, as per the former empires ancient customs. In the kings eyes, only a reconstituted College of Electors could possess such authority, with the failed attempt by the Frankfurt Parliament to include the Habsburgs into a newly unified German Empire, the Parliament turned to Prussia. Seeing Austrian ambivalence towards Prussia taking a powerful role in German affairs. All German states, excluding those of the Habsburgs, would be unified under Hohenzollern authority, the German Confederation remained the common government of German Europe. The lower house was elected by all taxpayers, but in a system based on the amount of taxes paid. This constitution remained in effect until the dissolution of the Prussian kingdom in 1918, Frederick William IV is buried with his wife in the crypt underneath the Church of Peace in the park of Sanssouci, at Potsdam

Wilhelm I
–
William I, or in German Wilhelm I, of the House of Hohenzollern was the King of Prussia and the first German Emperor, as well as the first Head of State of a united Germany. Under the leadership of William and his Minister President Otto von Bismarck, Prussia achieved the unification of Germany and the establishment of the German Empire. Contrary to the domineering Bismarck, William was described as polite, gentlemanly and, while a staunch conservative, the future king and emperor was born William Frederick Louis of Prussia in the Kronprinzenpalais in Berlin on 22 March 1797. As the second son of Prince Frederick William, himself son of King Frederick William II and his grandfather died the year he was born, at age 53, in 1797, and his father Frederick William III became king. He was educated from 1801 to 1809 by Johann Friedrich Gottlieb Delbrück, who was also in charge of the education of Williams brother, at age twelve, his father appointed him an officer in the Prussian army. William served in the army from 1814 onward, like his father he fought against Napoleon I of France during the part of the Napoleonic Wars known in Germany as the Befreiungskriege, and was reportedly a very brave soldier. He was made a Captain and won the Iron Cross for his actions at Bar-sur-Aube, the war and the fight against France left a lifelong impression on him, and he had a long-standing antipathy towards the French. In 1815, William was promoted to Major and commanded a battalion of the 1 and he fought under Gebhard Leberecht von Blücher at the Battles of Ligny and Waterloo. He also became an excellent diplomat by engaging in diplomatic missions after 1815, in 1816, William became the commander of the Stettiner Gardelandwehrbataillon and in 1818 was promoted to Generalmajor. The next year, William was appointed inspector of the VII. and this made him a spokesman of the Prussian Army within the House of Hohenzollern. He argued in favour of a strong, well-trained and well-equipped army, in 1820, William became commander of the 1. Gardedivision and in 1825 was promoted to commanding general of the III, in 1829, William married Princess Augusta von Sachsen-Weimar-Eisenach after Princess Elisa Radziwill, his cousin whom he had been attracted to, was deemed an inappropriate match by his father. William had been forced to abandon the relationship with Elisa in 1826, Augusta was the daughter of Grand Duke Karl Friedrich von Sachsen-Weimar-Eisenach. Their marriage was stable, but not a very happy one. In 1840 his older brother became King of Prussia, since he had no children, William was first in line to succeed him to the throne and thus was given the title Prinz von Preußen. Against his convictions but out of loyalty towards his brother, in 1847 William signed the bill setting up a Prussian parliament and took a seat in the upper chamber, the Herrenhaus. During the Revolutions of 1848, William successfully crushed a revolt in Berlin that was aimed at his elder brother, the use of cannon made him unpopular at the time and earned him the nickname Kartätschenprinz. Indeed, he had to flee to England for a while and he returned and helped to put down an uprising in Baden, where he commanded the Prussian army

Frederick III, German Emperor
–
Frederick III was German Emperor and King of Prussia for ninety-nine days in 1888, the Year of the Three Emperors. Friedrich Wilhelm Nikolaus Karl, known informally as Fritz, was the son of Emperor Wilhelm I and was raised in his familys tradition of military service. Following the unification of Germany in 1871 his father, then King of Prussia, Frederick was suffering from cancer of the larynx when he died on 15 June 1888, aged fifty-six, following unsuccessful medical treatments for his condition. Frederick married Victoria, Princess Royal, eldest daughter of Queen Victoria of the United Kingdom, the couple were well-matched, their shared liberal ideology led them to seek greater representation for commoners in the government. Frederick, in spite of his conservative militaristic family background, had developed liberal tendencies as a result of his ties with Britain, liberals in both Germany and Britain hoped that as emperor, Frederick III would move to liberalize the German Empire. Frederick and Victoria were great admirers of Prince Albert, Victorias father and they planned to rule as consorts, like Albert and Queen Victoria, and to reform what they saw as flaws in the executive branch that Bismarck had created for himself. The office of Chancellor, responsible to the Emperor, would be replaced with a British-style cabinet, government policy would be based on the consensus of the cabinet. Frederick described the Imperial Constitution as ingeniously contrived chaos and he sought to guard against such a turn by keeping the Crown Prince from a position of any influence and by using foul means as well as fair to make him unpopular. The timing of Fredericks death and the length of his reign are important topics among historians, Frederick William was born in the New Palace at Potsdam in Prussia on 18 October 1831. He was a scion of the House of Hohenzollern, rulers of Prussia, Fredericks father, Prince William, was a younger brother of King Frederick William IV and, having been raised in the military traditions of the Hohenzollerns, developed into a strict disciplinarian. Because of their differences, the couple did not have a marriage and, as a result, Frederick grew up in a troubled household. He had one sister, Louise, who was eight years his junior, Frederick also had a very good relationship with his uncle, King Frederick William IV, who has been called the romantic on the throne. Frederick grew up during a tumultuous political period as the concept of liberalism in Germany, overall, the liberals desired a government ruled by popular representation. When Frederick was 17, these emergent nationalistic and liberal sentiments sparked a series of uprisings across the German states. In Germany, their goal was to protect freedoms, such as the freedom of assembly and freedom of the press, although the uprisings ultimately brought about no lasting changes, liberal sentiments remained an influential force in German politics throughout Fredericks life. Despite the value placed by the Hohenzollern family on a military education. Accordingly, Frederick was thoroughly tutored in military traditions and the liberal arts. His private tutor was Ernst Curtius, a famous archaeologist, Frederick was a talented student, particularly good at foreign languages, becoming fluent in English and French, and studying Latin

World War II
–
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the worlds countries—including all of the great powers—eventually forming two opposing alliances, the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. Marked by mass deaths of civilians, including the Holocaust and the bombing of industrial and population centres. These made World War II the deadliest conflict in human history, from late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Poland, Finland, Romania and the Baltic states. In December 1941, Japan attacked the United States and European colonies in the Pacific Ocean, and quickly conquered much of the Western Pacific. The Axis advance halted in 1942 when Japan lost the critical Battle of Midway, near Hawaii, in 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained all of its territorial losses and invaded Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in South Central China and Burma, while the Allies crippled the Japanese Navy, thus ended the war in Asia, cementing the total victory of the Allies. World War II altered the political alignment and social structure of the world, the United Nations was established to foster international co-operation and prevent future conflicts. The victorious great powers—the United States, the Soviet Union, China, the United Kingdom, the Soviet Union and the United States emerged as rival superpowers, setting the stage for the Cold War, which lasted for the next 46 years. Meanwhile, the influence of European great powers waned, while the decolonisation of Asia, most countries whose industries had been damaged moved towards economic recovery. Political integration, especially in Europe, emerged as an effort to end pre-war enmities, the start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland, Britain and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously and this article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939, the exact date of the wars end is also not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 14 August 1945, rather than the formal surrender of Japan

Allies of World War II
–
The Allies of World War II, called the United Nations from the 1 January 1942 declaration, were the countries that together opposed the Axis powers during the Second World War. The Allies promoted the alliance as seeking to stop German, Japanese, at the start of the war on 1 September 1939, the Allies consisted of France, Poland and the United Kingdom, and dependent states, such as the British India. Within days they were joined by the independent Dominions of the British Commonwealth, Australia, Canada, New Zealand, Poland was a minor factor after its defeat in 1939, France was a minor factor after its defeat in 1940. China had already been into a war with Japan since the Marco Polo Bridge Incident of 1937. The alliance was formalised by the Declaration by United Nations, from 1 January 1942, however, the name United Nations was rarely used to describe the Allies during the war. The leaders of the Big Three – the UK, the Soviet Union, in 1945, the Allied nations became the basis of the United Nations. The origins of the Allied powers stem from the Allies of World War I, Germany resented signing Treaty of Versailles. The new Weimar republics legitimacy became shaken, by the early 1930s, the Nazi Party led by Adolf Hitler became the dominant revanchist movement in Germany and Hitler and the Nazis gained power in 1933. The Nazi regime demanded the cancellation of the Treaty of Versailles and made claims to German-populated Austria. The likelihood of war was high, and the question was whether it could be avoided through strategies such as appeasement, in Asia, when Japan seized Manchuria in 1931, the League of Nations condemned it for aggression against China. Japan responded by leaving the League of Nations in March 1933, after four quiet years, the Sino-Japanese War erupted in 1937 with Japanese forces invading China. The League of Nations condemned Japans actions and initiated sanctions on Japan, the United States, in particular, was angered at Japan and sought to support China. In March 1939, Germany took over Czechoslovakia, violating the Munich Agreement signed six months before, Britain and France decided that Hitler had no intention to uphold diplomatic agreements and responded by preparing for war. On 31 March 1939, Britain formed the Anglo-Polish military alliance in an effort to avert a German attack on the country, also, the French had a long-standing alliance with Poland since 1921. The Soviet Union sought an alliance with the powers. The agreement secretly divided the independent nations of eastern Europe between the two powers and assured adequate oil supplies for the German war machine, on 1 September 1939, Germany invaded Poland, two days later Britain and France declared war on Germany. Then, on 17 September 1939, the Soviet Union invaded Poland from the east, a Polish government-in-exile was set up and it continued to be one of the Allies, a model followed by other occupied countries. After a quiet winter, Germany in April 1940 invaded and quickly defeated Denmark, Norway, Belgium, Britain and its Empire stood alone against Hitler and Mussolini

Deutz, Cologne
–
Cologne-Deutz, often just Deutz is an inner city part of Cologne, Germany and a formerly independent town. Deutz was established under Roman Emperor Constantine I in 310 AD, when he established Castrum Divitia, camp and city were linked via a bridge from the same time. During the Middle Ages, Deutz was an important centre of learning in medieval Germany, up into the early Middle Ages it was known by the Latin name Divitia, from the 10th century as Tuitium. It was located on the bank of the Rhine, opposite Cologne. In 1002, the old castle in Deutz was made a Benedictine monastery by Heribert, archbishop of Cologne, permission to fortify the town was in 1230 granted to the citizens by the archbishop of Cologne, between whom and the counts of Berg it was divided in 1240. It was burnt in 1376,1445 and 1583, and in 1678, after the Treaties of Nijmegen, in 1869, Nikolaus August Otto and Eugen Langen moved their company NA Otto and Cie to Deutz, where the company was renamed to Gasmotoren-Fabrik Deutz. Arguably, this is the birthplace of the modern Otto-engine, precursor for all internal combustion engines. Deutz was formally incorporated into Cologne in 1888, modern Deutz is the part of the Cologne city centre on the right bank of the river. Politically Deutz is part of the administrative district Innenstadt, the painter August Lemmer was born in Deutz

Love padlocks
–
A love lock or love padlock is a padlock which sweethearts lock to a bridge, fence, gate, or similar public fixture to symbolize their love. Typically the sweethearts names or initials are inscribed on the padlock, since the 2000s, love locks have proliferated at an increasing number of locations worldwide. They are now treated by municipal authorities as litter or vandalism. However, there are authorities who embrace them, and who use them as fundraising projects or tourism attractions. The history of love padlocks dates back at least 100 years to a melancholic Serbian tale of World War I, a local schoolmistress named Nada, who was from Vrnjačka Banja, fell in love with a Serbian officer named Relja. After they committed to each other Relja went to war in Greece where he fell in love with a woman from Corfu. As a consequence, Relja and Nada broke off their engagement, Nada never recovered from that devastating blow, and after some time she died due to heartbreak from her unfortunate love. In the rest of Europe, love padlocks started appearing in the early 2000s, the reasons love padlocks started to appear vary between locations and in many instances are unclear. However, in Rome, the ritual of affixing love padlocks to the bridge Ponte Milvio can be attributed to the 2006 book I Want You by Italian author Federico Moccia, who made a film adaptation in 2007. Some youths brought tools to remove them by night a few later, after a video was made by an imam saying that love padlocks are forbidden in Islam. Authorities in Canberra, Australia, decided in February 2015 to remove love locks from a bridge that was becoming a location to affix them. A bridge in Paris was mentioned by authorities as an example of an overloaded bridge, on 20 May 2015, council authorities in Melbourne, Australia, began removing love locks from Southgate footbridge due to safety concerns. Around 22,000 love locks were reported to have been fixed to the railings, in Toowoomba, Australia, love locks have been appearing at Picnic Point, a heritage-listed tourist attraction featuring a park and lookout at the top of the Great Dividing Range. In Adelaide, locks can be found along the Adelaide Uni footbridge across the Torrens River, in Brisbane, locks have been attached to the security fence on the Kurilpa Bridge. In Canada, love padlocks appearing along the Wild Pacific Trail in Ucluelet on Vancouver Island, have caused controversy as some regard them as a distraction from nature. Love padlocks were removed from the Humber Bay Arch Bridge in Toronto, due to concerns over aesthetics, ottawas Corktown Footbridge has also attracted love locks. The lovelocks of the Pont des Arts disappeared during the night of 11 May 2010, they had been removed by a student of the nearby École des Beaux-Arts to make a sculpture. Love locks immediately began appearing on the Pont de lArchevêché and have spread to at least 11 Seine bridges, the Canal Saint Martin footbridges

The Virtual International Authority File is an international authority file. It is a joint project of national libraries and operated by the Online Computer Library Center. The project was initiated by the US Library of Congress, the German National Library, the National Library of France joined the project on October 5,2007. The project transitions to a service of the OCLC on April 4,2012, the aim is to link the national authority files to a single virtual authority file. In this file, identical records from the different data sets are linked together, a VIAF record receives a standard data number, contains the primary see and see also records from the original records, and refers to the original authority records. The data are available online and are available for research and data exchange. Reciprocal updating uses the Open Archives Initiative Protocol for Metadata Harvesting protocol, the file numbers are also being added to Wikipedia biographical articles and are incorporated into Wikidata. VIAFs clustering algorithm is run every month, as more data are added from participating libraries, clusters of authority records may coalesce or split, leading to some fluctuation in the VIAF identifier of certain authority records
