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

Czech Republic
–
The Czech Republic, also known as Czechia, is a nation state in Central Europe bordered by Germany to the west, Austria to the south, Slovakia to the east and Poland to the northeast. The Czech Republic covers an area of 78,866 square kilometres with mostly temperate continental climate and it is a unitary parliamentary republic, has 10.5 million inhabitants and the capital and largest city is Prague, with over 1.2 million residents. The Czech Republic includes the territories of Bohemia, Moravia. The Czech state was formed in the late 9th century as the Duchy of Bohemia under the Great Moravian Empire, after the fall of the Empire in 907, the centre of power transferred from Moravia to Bohemia under the Přemyslid dynasty. In 1002, the duchy was formally recognized as part of the Holy Roman Empire, becoming the Kingdom of Bohemia in 1198 and reaching its greatest territorial extent in the 14th century. Following the Battle of Mohács in 1526, the whole Crown of Bohemia was gradually integrated into the Habsburg Monarchy alongside the Archduchy of Austria, the Protestant Bohemian Revolt against the Catholic Habsburgs led to the Thirty Years War. After the Battle of the White Mountain, the Habsburgs consolidated their rule, reimposed Roman Catholicism, the Czech part of Czechoslovakia was occupied by Germany in World War II, and was liberated in 1945 by the armies of the Soviet Union and the United States. The Czech country lost the majority of its German-speaking inhabitants after they were expelled following the war, the Communist Party of Czechoslovakia won the 1946 elections. Following the 1948 coup détat, Czechoslovakia became a one-party communist state under Soviet influence, in 1968, increasing dissatisfaction with the regime culminated in a reform movement known as the Prague Spring, which ended in a Soviet-led invasion. Czechoslovakia remained occupied until the 1989 Velvet Revolution, when the communist regime collapsed, on 6 March 1990, the Czech Socialistic Republic was renamed to the Czech Republic. On 1 January 1993, Czechoslovakia peacefully dissolved, with its constituent states becoming the independent states of the Czech Republic and the Slovak Republic. The Czech Republic joined NATO in 1999 and the European Union in 2004, it is a member of the United Nations, the OECD, the OSCE, and it is a developed country with an advanced, high income economy and high living standards. The UNDP ranks the country 14th in inequality-adjusted human development, the Czech Republic also ranks as the 6th most peaceful country, while achieving strong performance in democratic governance. It has the lowest unemployment rate in the European Union, the traditional English name Bohemia derives from Latin Boiohaemum, which means home of the Boii. The current name comes from the endonym Čech, spelled Cžech until the reform in 1842. The name comes from the Slavic tribe and, according to legend, their leader Čech, the etymology of the word Čech can be traced back to the Proto-Slavic root *čel-, meaning member of the people, kinsman, thus making it cognate to the Czech word člověk. The country has traditionally divided into three lands, namely Bohemia in the west, Moravia in the southeast, and Czech Silesia in the northeast. Following the dissolution of Czechoslovakia at the end of 1992, the Czech part of the former nation found itself without a common single-word geographical name in English, the name Czechia /ˈtʃɛkiə/ was recommended by the Czech Ministry of Foreign Affairs

Districts of the Czech Republic
–
In 1960, Czechoslovakia was re-divided into districts often without regard to traditional division and local relationships. In the area of the Czech Republic, there were 75 districts, a reform in effect since January 2003 replaced the districts with 204 Municipalities with Extended Competence (obce s rozšířenou působností, also obce III. Stupně - third-level municipalities, unofficially also called little districts which took over most of the administration of the district authorities. Some of these are divided between Municipalities with Commissioned Local Authority. The old districts still exist as units and remain as seats of some of the offices, especially courts, police. In 2007 the borders of the districts were slightly adjusted and 119 municipalities are now within different districts, regions of the Czech Republic ISO 3166-2, CZ http, //www. czso. cz/lexikon/mos2003. nsf/index

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

Duchy of Bohemia
–
The Duchy of Bohemia, also referred to as the Czech Duchy, was a monarchy and a principality in Central Europe during the Early and High Middle Ages. It was formed around 870 by Czechs as part of the Great Moravian realm, the Bohemian lands separated from disintegrating Moravia after Duke Spytihněv swore fidelity to the East Frankish king Arnulf in 895. In 973 the Diocese of Prague was founded through the joint efforts of Duke Boleslaus II, late Duke Wenceslaus I of Bohemia, killed by his younger brother Boleslaus in 935, became the lands patron saint. The Duchy of Bohemia was raised to a hereditary Kingdom of Bohemia, the Přemyslids remained in power throughout the High Middle Ages, until the extinction of the male line with the death of King Wenceslaus III in 1306. The lands encompassed by the Bohemian Forest, the Ore Mountains, the Sudetes, in the 7th century the local Czech people were part of the union led by the Frankish merchant Samo. Bohemia as a term, probably derived from the Celtic Boii tribes. In 805 Emperor Charlemagne prepared to conquer the lands, invading Bohemia in 805, however the Czech forces shirked from open battle and retired into the deep forests to launch guerilla attacks. After forty days the emperor had to withdraw his forces for the lack of supplies, when the Frankish forces returned the next year burning and plundering the Bohemian lands, the local tribes finally had to submit and became dependent on the Carolingian Empire. While the Frankish realm disintegrated in the mid 9th century, Bohemia came in the reach of the Great Moravian state set up about 830, in 874 the Mojmir duke Svatopluk I reached an agreement with the East Frankish king Louis the German and confirmed his Bohemian dominion. With the fragmentation of Great Moravia under the pressure of the Magyar incursions around 900 and he and his younger brother Vratislaus then ruled over Central Bohemia around Prague. They were able to protect their realm from the Magyar forces which crushed an East Frankish army in the 907 Battle of Pressburg during the Hungarian conquest of the Carpathian Basin. Wenceslaus maintained his authority by submitting to King Henry in 929. Assuming the Bohemian throne in 935, Duke Boleslaus conquered the adjacent lands of Moravia and Silesia and he offered opposition to Henrys successor King Otto I, stopped paying the tribute, attacked an ally of the Saxons in northwest Bohemia and in 936 moved into Thuringia. Overwhelming marauding Hungarians had the benefits for Germans and Czechs. Less obvious is what Boleslav wanted to gain with his participation in the war against the Obotrite tribes in far north, probably Boleslav wanted to ensure that German neighbors did not interfere with his expansion of Bohemia to the east. Significantly, the Bishopric of Prague, founded in 973 during the reign of Duke Boleslaus II, was subordinated to the Archbishopric of Mainz, in 1002 Duke Vladivoj was enfeoffed with the Duchy of Bohemia from the hands of King Henry II of Germany. With this act, what had been a sovereign duchy became part of the Holy Roman Empire. After Vladivoj died the year, the Polish duke Bolesław I Chrobry invaded Bohemia and Moravia
