Warsaw Pact
–
The Warsaw Pact was the military complement to the Council for Mutual Economic Assistance, the regional economic organization for the communist states of Central and Eastern Europe. While the Warsaw Pact was established as a balance of power or counterweight to NATO, instead, the conflict was fought on an ideological basis and in proxy wars. Both NATO and the Warsaw Pact led to the expansion of military forces and its largest military engagement was the Warsaw Pact invasion of Czechoslovakia in August 1968, which, in part, resulted in Albania withdrawing from the pact less than a month later. The Pact began to unravel in its entirety with the spread of the Revolutions of 1989 through the Eastern Bloc, beginning with the Solidarity movement in Poland, East Germany and Poland withdrew from the Pact in 1990. On 25 February 1991, the Pact was declared at an end at a meeting of defence, the USSR itself was dissolved in December 1991, although most of the former Soviet republics formed the Collective Security Treaty Organization shortly thereafter. Throughout the following 20 years, the seven Warsaw Pact countries outside the USSR each joined NATO, in the Western Bloc, the Warsaw Treaty Organization of Friendship, Cooperation, and Mutual Assistance is often called the Warsaw Pact military alliance—abbreviated WAPA, Warpac, and WP. Therefore, although ostensibly an international collective security alliance, the USSR dominated the Warsaw Treaty armed forces, the strategy behind the formation of the Warsaw Pact was driven by the desire of the Soviet Union to dominate Central and Eastern Europe. The Soviets wanted to keep their part of Europe theirs and not let the Americans take it from them and this policy was driven by ideological and geostrategic reasons. Ideologically, the Soviet Union arrogated the right to define socialism and communism, geostrategic principles also drove the Soviet Union to prevent invasion of its territory by Western European powers. Before the creation of the Warsaw Pact, Czechoslovak leadership, fearful of a rearmed Germany, sought to create a security pact with East Germany and these states protested strongly against the re-militarization of West Germany. The Warsaw Pact was primarily put in place as a consequence of the rearming of West Germany inside NATO, Soviet leaders, like many European countries on both sides of the Iron Curtain, feared Germany being once again a military power and a direct threat. The terrible consequences of German militarism remained a fresh memory among the Soviets, previously, in March 1954, the USSR, fearing the restoration of German militarism in West Germany, requested admission to NATO. The Soviet request to join NATO arose in the aftermath of the Berlin Conference of January–February 1954. James Dunn, who met in Paris with Eden, Adenauer and Robert Schuman, affirmed that the object should be to avoid discussion with the Russians, according to John Gaddis there was little inclination in Western capitals to explore this offer from USSR. But Eden, Dulles and Bidault opposed the proposal, the Soviets then decided to make a new proposal to the governments of the USA, UK and France to accept the participation of the USA in the proposed General European Agreement. Again all proposals, including the request to join NATO, were rejected by the UK, US, emblematic was the position of British General Hastings Ismay, supporter of NATO expansion, who said that NATO must grow until the whole free world gets under one umbrella. He opposed the request to join NATO made by the USSR in 1954 saying that the Soviet request to join NATO is like an unrepentant burglar requesting to join the police force, in April 1954 Adenauer made his first visit to the USA meeting Nixon, Eisenhower and Dulles. Ratification of EDC was delaying but the US representatives made it clear to Adenauer that EDC would have to become a part of NATO, memories of the Nazi occupation were still strong, and the rearmament of Germany was feared by France too

Aircraft
–
An aircraft is a machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the lift of an airfoil. The human activity that surrounds aircraft is called aviation, crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as type, aircraft propulsion, usage. Each of the two World Wars led to technical advances. Consequently, the history of aircraft can be divided into five eras, Pioneers of flight, first World War,1914 to 1918. Aviation between the World Wars,1918 to 1939, Second World War,1939 to 1945. Postwar era, also called the jet age,1945 to the present day, aerostats use buoyancy to float in the air in much the same way that ships float on the water. They are characterized by one or more large gasbags or canopies, filled with a relatively low-density gas such as helium, hydrogen, or hot air, which is less dense than the surrounding air. When the weight of this is added to the weight of the aircraft structure, a balloon was originally any aerostat, while the term airship was used for large, powered aircraft designs – usually fixed-wing. In 1919 Frederick Handley Page was reported as referring to ships of the air, in the 1930s, large intercontinental flying boats were also sometimes referred to as ships of the air or flying-ships. – though none had yet been built, the advent of powered balloons, called dirigible balloons, and later of rigid hulls allowing a great increase in size, began to change the way these words were used. Huge powered aerostats, characterized by an outer framework and separate aerodynamic skin surrounding the gas bags, were produced. There were still no fixed-wing aircraft or non-rigid balloons large enough to be called airships, then several accidents, such as the Hindenburg disaster in 1937, led to the demise of these airships. Nowadays a balloon is an aerostat and an airship is a powered one. A powered, steerable aerostat is called a dirigible, sometimes this term is applied only to non-rigid balloons, and sometimes dirigible balloon is regarded as the definition of an airship. Non-rigid dirigibles are characterized by a moderately aerodynamic gasbag with stabilizing fins at the back and these soon became known as blimps. During the Second World War, this shape was adopted for tethered balloons, in windy weather

The Hague
–
The Hague is a city on the western coast of the Netherlands, and the capital city of the province of South Holland. With a population of 520,704 inhabitants and more than one million including the suburbs, it is the third-largest city of the Netherlands. The Rotterdam The Hague Metropolitan Area, with a population of approximately 2.7 million, is the 12th-largest in the European Union and the most populous in the country. Located in the west of the Netherlands, The Hague is in the centre of the Haaglanden conurbation and lies at the southwest corner of the larger Randstad conurbation. The Hague is the seat of the Dutch government, parliament, the Supreme Court, and the Council of State, but the city is not the capital of the Netherlands, which constitutionally is Amsterdam. King Willem-Alexander of the Netherlands plans to live at Huis ten Bosch and works at Noordeinde Palace in The Hague, the Hague is also home to the world headquarters of Royal Dutch Shell and numerous other major Dutch companies. The Hague originated around 1230, when Count Floris IV of Holland purchased land alongside a pond, in 1248, his son and successor William II, King of the Romans, decided to extend the residence to a palace, which would later be called the Binnenhof. He died in 1256 before this palace was completed but parts of it were finished by his son Floris V, of which the Ridderzaal and it is still used for political events, such as the annual speech from the throne by the Dutch monarch. From the 13th century onwards, the counts of Holland used The Hague as their administrative centre, the village that originated around the Binnenhof was first mentioned as Haga in a charter dating from 1242. In the 15th century, the smarter des Graven hage came into use, literally The Counts Wood, with connotations like The Counts Hedge, s-Gravenhage was officially used for the city from the 17th century onwards. Today, this name is used in some official documents like birth. The city itself uses Den Haag in all its communication and their seat was located in The Hague. At the beginning of the Eighty Years War, the absence of city walls proved disastrous, in 1575, the States of Holland even considered demolishing the city but this proposal was abandoned, after mediation by William of Orange. From 1588, The Hague also became the seat of the government of the Dutch Republic, in order for the administration to maintain control over city matters, The Hague never received official city status, although it did have many of the privileges normally granted only to cities. In modern administrative law, city rights have no place anymore, only in 1806, when the Kingdom of Holland was a puppet state of the First French Empire, was the settlement granted city rights by Louis Bonaparte. After the Napoleonic Wars, modern-day Belgium and the Netherlands were combined in the United Kingdom of the Netherlands to form a buffer against France, as a compromise, Brussels and Amsterdam alternated as capital every two years, with the government remaining in The Hague. After the separation of Belgium in 1830, Amsterdam remained the capital of the Netherlands, when the government started to play a more prominent role in Dutch society after 1850, The Hague quickly expanded. The growing city annexed the rural municipality of Loosduinen partly in 1903, the city sustained heavy damage during World War II

Netherlands
–
The Netherlands, also informally known as Holland is the main constituent country of the Kingdom of the Netherlands. It is a densely populated country located in Western Europe with three territories in the Caribbean. The European part of the Netherlands borders Germany to the east, Belgium to the south, and the North Sea to the northwest, sharing borders with Belgium, the United Kingdom. The three largest cities in the Netherlands are Amsterdam, Rotterdam and The Hague, Amsterdam is the countrys capital, while The Hague holds the Dutch seat of parliament and government. The port of Rotterdam is the worlds largest port outside East-Asia, the name Holland is used informally to refer to the whole of the country of the Netherlands. Netherlands literally means lower countries, influenced by its low land and flat geography, most of the areas below sea level are artificial. Since the late 16th century, large areas have been reclaimed from the sea and lakes, with a population density of 412 people per km2 –507 if water is excluded – the Netherlands is classified as a very densely populated country. Only Bangladesh, South Korea, and Taiwan have both a population and higher population density. Nevertheless, the Netherlands is the worlds second-largest exporter of food and agricultural products and this is partly due to the fertility of the soil and the mild climate. In 2001, it became the worlds first country to legalise same-sex marriage, the Netherlands is a founding member of the EU, Eurozone, G-10, NATO, OECD and WTO, as well as being a part of the Schengen Area and the trilateral Benelux Union. The first four are situated in The Hague, as is the EUs criminal intelligence agency Europol and this has led to the city being dubbed the worlds legal capital. The country also ranks second highest in the worlds 2016 Press Freedom Index, the Netherlands has a market-based mixed economy, ranking 17th of 177 countries according to the Index of Economic Freedom. It had the thirteenth-highest per capita income in the world in 2013 according to the International Monetary Fund, in 2013, the United Nations World Happiness Report ranked the Netherlands as the seventh-happiest country in the world, reflecting its high quality of life. The Netherlands also ranks joint second highest in the Inequality-adjusted Human Development Index, the region called Low Countries and the country of the Netherlands have the same toponymy. Place names with Neder, Nieder, Nether and Nedre and Bas or Inferior are in use in all over Europe. They are sometimes used in a relation to a higher ground that consecutively is indicated as Upper, Boven, Oben. In the case of the Low Countries / the Netherlands the geographical location of the region has been more or less downstream. The geographical location of the region, however, changed over time tremendously

Guatemala City
–
Guatemala City, locally known as Guatemala or Guate, is the capital and largest city of the Republic of Guatemala, and the most populous in Central America. The city is located in the part of the country. In 2009, it had a population of 1,075,000, Guatemala City is also the capital of the local Municipality of Guatemala and of the Guatemala Department. Human settlement on the present site of Guatemala City began with the Maya who built a city at Kaminaljuyu, the Spanish colonists established a small town, which was made a capital city in 1775. At this period the Central Square with the Cathedral and Royal Palace were constructed, after Central American independence from Spain the city became the capital of the United Provinces of Central America in 1821. The 19th century saw the construction of the monumental Carrera Theater in the 1850s, at this time the city was expanding around the 30 de junio Boulevard and elsewhere, displacing native settlements from the ancient site. Earthquakes in 1917–1918 destroyed many historic structures, during the Guatemalan Civil War, terror attacks beginning with the burning of the Spanish Embassy in 1980 led to severe destruction and loss of life in the city. In May 2010 two disasters struck, the eruption of the Pacaya volcano, and two days later Tropical Storm Agatha, Guatemala City serves as the economic, governmental, and cultural epicenter of the nation of Guatemala. Guatemala City is subdivided into 22 zones designed by the engineering of Raúl Aguilar Batres, each one with its own streets and avenues. Zones are numbered 1-25 with Zones 20,22 and 23 not existing as they would have fallen in two other municipalities territory. Addresses are assigned according to the street or avenue number, followed by a dash, the zones are assigned in a spiral form starting in downtown Guatemala city. Efforts to revitalize this important part of the city have been undertaken by the government and have been very successful thus far. This plan denominated POT aims to allow taller building structures of mixed uses to be next to large arterial roads and gradually decline in height. It is also worth mentioning, that due to the Airport being in the city, to the south and this limits the maximum height for a building, at 60 metres in Zone 10, up to 95 metres in Zone 1. The city is located in the South-Central area of the country and has a lot of green areas, besides the parks, the city offers a portfolio of entertainment in the region, focused on the so-called Zona Viva and the Calzada Roosevelt as well as four degrees North. Also include projects such as Zona Pradera and Interamerica´s World Financial Center http, the location of the La Aurora international airport within the city limits the construction of skyscrapers, changing the limits permitted directly by its location within the urban area. According to the 2017 census, the Guatemala City metropolitan area had a population of 3.3 million, making it the most populous urban agglomeration in Central America. The growth of the population has been robust since then

Guatemala
–
With an estimated population of around 15.8 million, it is the most populated state in Central America. Guatemala is a democracy, its capital and largest city is Nueva Guatemala de la Asunción. The territory of modern Guatemala once formed the core of the Maya civilization, most of the country was conquered by the Spanish in the 16th century, becoming part of the viceroyalty of New Spain. Guatemala attained independence in 1821 as part of the Federal Republic of Central America, from the mid to late 19th century, Guatemala experienced chronic instability and civil strife. Beginning in the early 20th century, it was ruled by a series of dictators backed by the United Fruit Company, in 1944, authoritarian leader Jorge Ubico was overthrown by a pro-democratic military coup, initiating a decade-long revolution that led to sweeping social and economic reforms. A U. S. -backed military coup in 1954 ended the revolution, from 1960 to 1996, Guatemala endured a bloody civil war fought between the US-backed government and leftist rebels, including genocidal massacres of the Maya population perpetrated by the military. As of 2014, Guatemala ranks 31st of 33 Latin American and Caribbean countries in terms of the Human Development Index, Guatemalas abundance of biologically significant and unique ecosystems includes a large number of endemic species and contributes to Mesoamericas designation as a biodiversity hotspot. The country is known for its rich and distinct culture. The name Guatemala comes from the Nahuatl word Cuauhtēmallān, or place of many trees and this was the name the Tlaxcaltecan soldiers who accompanied Pedro de Alvarado during the Spanish Conquest gave to this territory. The first evidence of habitation in Guatemala dates back to 12,000 BC. Evidence, such as obsidian arrowheads found in parts of the country. There is archaeological proof that early Guatemalan settlers were hunters and gatherers, pollen samples from Petén and the Pacific coast indicate that maize cultivation had been developed by 3500 BC. Sites dating back to 6500 BC have been found in the Quiché region in the Highlands, archaeologists divide the pre-Columbian history of Mesoamerica into the Preclassic period, the Classic period, and the Postclassic period. Until recently, the Preclassic was regarded as a period, with small villages of farmers who lived in huts. This period is characterized by urbanisation, the emergence of independent city-states and this lasted until approximately 900 AD, when the Classic Maya civilization collapsed. The Maya abandoned many of the cities of the lowlands or were killed off by a drought-induced famine. The cause of the collapse is debated, but the Drought Theory is gaining currency, supported by such as lakebeds, ancient pollen. A series of prolonged droughts, among other such as overpopulation, in what is otherwise a seasonal desert is thought to have decimated the Maya

Paris
–
Paris is the capital and most populous city of France. It has an area of 105 square kilometres and a population of 2,229,621 in 2013 within its administrative limits, the agglomeration has grown well beyond the citys administrative limits. By the 17th century, Paris was one of Europes major centres of finance, commerce, fashion, science, and the arts, and it retains that position still today. The aire urbaine de Paris, a measure of area, spans most of the Île-de-France region and has a population of 12,405,426. It is therefore the second largest metropolitan area in the European Union after London, the Metropole of Grand Paris was created in 2016, combining the commune and its nearest suburbs into a single area for economic and environmental co-operation. Grand Paris covers 814 square kilometres and has a population of 7 million persons, the Paris Region had a GDP of €624 billion in 2012, accounting for 30.0 percent of the GDP of France and ranking it as one of the wealthiest regions in Europe. The city is also a rail, highway, and air-transport hub served by two international airports, Paris-Charles de Gaulle and Paris-Orly. Opened in 1900, the subway system, the Paris Métro. It is the second busiest metro system in Europe after Moscow Metro, notably, Paris Gare du Nord is the busiest railway station in the world outside of Japan, with 262 millions passengers in 2015. In 2015, Paris received 22.2 million visitors, making it one of the top tourist destinations. The association football club Paris Saint-Germain and the rugby union club Stade Français are based in Paris, the 80, 000-seat Stade de France, built for the 1998 FIFA World Cup, is located just north of Paris in the neighbouring commune of Saint-Denis. Paris hosts the annual French Open Grand Slam tennis tournament on the red clay of Roland Garros, Paris hosted the 1900 and 1924 Summer Olympics and is bidding to host the 2024 Summer Olympics. The name Paris is derived from its inhabitants, the Celtic Parisii tribe. Thus, though written the same, the name is not related to the Paris of Greek mythology. In the 1860s, the boulevards and streets of Paris were illuminated by 56,000 gas lamps, since the late 19th century, Paris has also been known as Panam in French slang. Inhabitants are known in English as Parisians and in French as Parisiens and they are also pejoratively called Parigots. The Parisii, a sub-tribe of the Celtic Senones, inhabited the Paris area from around the middle of the 3rd century BC. One of the areas major north-south trade routes crossed the Seine on the île de la Cité, this place of land and water trade routes gradually became a town

Ministry of Foreign Affairs (Poland)
–
It is considered to be one of the most important offices of state. The head of the ministry is a secretary of state. The Ministry of Foreign Affairs is responsible primarily for maintaining good, in doing so it is required to act primarily as a representative of the Polish people. To this end all Polish diplomatic missions around the world are subordinate to the Ministry of Foreign Affairs, the ministry is considered to be one of Polands most important, with the minister of foreign affairs ranking amongst the most influential people in Polish politics. This position is reserved for seasoned, professional politicians, and is thought to require a great deal of tact and intellect. However, the ministry began to fulfil its ascribed duties truly only after the fall of the Regency Council, adoption of the Treaty of Versailles, the ministry was then, until 1939, located in central Warsaw, with its seat in the Brühl Palace on Piłsudski Square. During this period Count Edward Raczyński, a man who was later to become President of the government in exile, was the minister responsible, the departments for regional affairs exist to monitor the internal situation and politics of the countries within the area of any one specific departments competence. They coordinate development of relations, initiate the related undertakings. These departments oversee the issue of Poland’s participation in the structures of multilateral cooperation with any relevant partner states and they are responsible for the substantive activity of relevant Polish diplomatic missions abroad

Airline ticket
–
An airline ticket is a document, issued by an airline or a travel agency, to confirm that an individual has purchased a seat on a flight on an aircraft. This document is used to obtain a boarding pass, at the airport. Then with the pass and the attached ticket, the passenger is allowed to board the aircraft. There are two sorts of airline tickets - the older style with coupons now referred to as a ticket. Regardless of the type, all tickets contain details of the following information, a ticket number, including the airlines 3 digit code at the start of the number. The cities the ticket is valid for travel between, flight that the ticket is valid for. The Fare Basis, an alpha or alpha-numeric code that identifies the fare, dates that the ticket is valid for. Form of payment, i. e. details of how the ticket was paid for, the Rate of Exchange used to calculate any international parts of the fare and tax. A Fare Construction or Linear showing the breakdown of the total fare, IATA announced that as of June 1,2008, IATA-member airlines will no longer issue any paper tickets. A ticket is only good on the airline for which it was purchased. However, an airline can endorse the ticket, so that it may be accepted by other airlines, sometimes on standby basis or with a confirmed seat, usually the ticket is for a specific flight. It is also possible to purchase a ticket, which allows travel on any flight between the destinations listed on the ticket. The cost for doing this is greater than a ticket for a specific flight, however, the lower cost tickets are usually not refundable and may carry many additional restrictions. The carrier is represented by a standardized 2-letter code, in the example above, Thai Airways is TG. The departure and destination cities are represented by International Air Transport Association airport codes, in the example above, Munich is MUC and Bangkok is BKK. The International Air Transport Association is the standard setting organization, only one person can use a ticket. If multiple people are traveling together, the tickets are linked together by the record locator or reservation number. If not, most airlines can cross-reference the tickets together in their reservation systems and this practice consisted of selling the ticket to other travellers, after which the seller accompanied the buyer at the time of departure to the airport

Franc
–
The franc is the name of several currency units. The French franc was the currency of France until the euro was adopted in 1999. The Swiss franc is a world currency today due to the prominence of Swiss financial institutions. The name is said to derive from the Latin inscription francorum rex used on early French coins and until the 18th century, or from the French franc, the countries that use francs include Switzerland, Liechtenstein, and most of Francophone Africa. Before the introduction of the euro, francs were used in France, Belgium and Luxembourg, while Andorra. The franc was used within the French Empires colonies, including Algeria and Cambodia. The franc is sometimes italianised or hispanicised as the franco, for instance in Luccan franco, one franc is typically divided into 100 centimes. It was equivalent to one livre tournois, the French franc was the name of a gold coin issued in France from 1360 until 1380, then a silver coin issued between 1575 and 1641. The franc finally became the currency from 1795 until 1999. Though abolished as a coin by Louis XIII in 1641 in favor of the gold louis and silver écu. The franc was also minted for many of the former French colonies, such as Morocco, Algeria, French West Africa, today, after independence, many of these countries continue to use the franc as their standard denomination. The value of the French franc was locked to the euro at 1 euro =6, fourteen African countries use the franc CFA, originally worth 1.7 French francs and then from 1948,2 francs but after January 1994 worth only 0.01 French franc. Therefore, from January 1999,1 CFA franc is equivalent to €0.00152449, a separate circulates in Frances Pacific territories, worth €0.0084. In 1981, The Comoros established an arrangement with the French government similar to that of the CFA franc, originally,50 Comorian francs were worth 1 French franc. In January 1994, the rate was changed to 75 Comorian francs to the French franc, since 1999, the currency has been pegged to the euro. The conquest of most of western Europe by Revolutionary and Napoleonic France led to the wide circulation. Newly unified Italy adopted the lira on a basis in 1862. In the 1870s the gold value was made the fixed standard, the 1921 monetary union of Belgium and Luxembourg survived, however, forming the basis for full economic union in 1932

Kilogram
–
The kilogram or kilogramme is the base unit of mass in the International System of Units and is defined as being equal to the mass of the International Prototype of the Kilogram. The avoirdupois pound, used in both the imperial and US customary systems, is defined as exactly 0.45359237 kg, making one kilogram approximately equal to 2.2046 avoirdupois pounds. Other traditional units of weight and mass around the world are also defined in terms of the kilogram, the gram, 1/1000 of a kilogram, was provisionally defined in 1795 as the mass of one cubic centimeter of water at the melting point of ice. The final kilogram, manufactured as a prototype in 1799 and from which the IPK was derived in 1875, had an equal to the mass of 1 dm3 of water at its maximum density. The kilogram is the only SI base unit with an SI prefix as part of its name and it is also the only SI unit that is still directly defined by an artifact rather than a fundamental physical property that can be reproduced in different laboratories. Three other base units and 17 derived units in the SI system are defined relative to the kilogram, only 8 other units do not require the kilogram in their definition, temperature, time and frequency, length, and angle. At its 2011 meeting, the CGPM agreed in principle that the kilogram should be redefined in terms of the Planck constant, the decision was originally deferred until 2014, in 2014 it was deferred again until the next meeting. There are currently several different proposals for the redefinition, these are described in the Proposed Future Definitions section below, the International Prototype Kilogram is rarely used or handled. In the decree of 1795, the term gramme thus replaced gravet, the French spelling was adopted in the United Kingdom when the word was used for the first time in English in 1797, with the spelling kilogram being adopted in the United States. In the United Kingdom both spellings are used, with kilogram having become by far the more common, UK law regulating the units to be used when trading by weight or measure does not prevent the use of either spelling. In the 19th century the French word kilo, a shortening of kilogramme, was imported into the English language where it has used to mean both kilogram and kilometer. In 1935 this was adopted by the IEC as the Giorgi system, now known as MKS system. In 1948 the CGPM commissioned the CIPM to make recommendations for a practical system of units of measurement. This led to the launch of SI in 1960 and the subsequent publication of the SI Brochure, the kilogram is a unit of mass, a property which corresponds to the common perception of how heavy an object is. Mass is a property, that is, it is related to the tendency of an object at rest to remain at rest, or if in motion to remain in motion at a constant velocity. Accordingly, for astronauts in microgravity, no effort is required to hold objects off the cabin floor, they are weightless. However, since objects in microgravity still retain their mass and inertia, the ratio of the force of gravity on the two objects, measured by the scale, is equal to the ratio of their masses. On April 7,1795, the gram was decreed in France to be the weight of a volume of pure water equal to the cube of the hundredth part of the metre
