Given the question: Information: - Berlin is the capital and the largest city of Germany as well as one of its constituent 16 states. With a population of approximately 3.5 million people, Berlin is the second most populous city proper and the seventh most populous urban area in the European Union. Located in northeastern Germany on the banks of rivers Spree and Havel, it is the centre of the Berlin-Brandenburg Metropolitan Region, which has about 6 million residents from more than 180 nations. Due to its location in the European Plain, Berlin is influenced by a temperate seasonal climate. Around one-third of the city's area is composed of forests, parks, gardens, rivers and lakes. - The Warsaw Pact, formally the Treaty of Friendship, Co-operation, and Mutual Assistance and sometimes, informally, WarPac. was a collective defense treaty among the Soviet Union and seven other Soviet satellite states in Central and Eastern Europe in existence during the Cold War. The Warsaw Pact was the military complement to the Council for Mutual Economic Assistance (CoMEcon), the regional economic organization for the communist states of Central and Eastern Europe. The Warsaw Pact was created in reaction to the integration of West Germany into NATO in 1955 per the London and Paris Conferences of 1954, but it is also considered to have been motivated by Soviet desires to maintain control over military forces in Central and Eastern Europe. - The Spree is a river that flows through the Saxony, Brandenburg and Berlin states of Germany, and in the Usti nad Labem region of the Czech Republic. Approximately in length, it is a left bank tributary of the River Havel, which itself flows into the Elbe and then the North Sea. It is the river on which the original centre of Berlin was built. - East Berlin existed between 1949 and 1990 and consisted of the Soviet sector of Berlin established in 1945. The American, British, and French sectors became West Berlin, strongly associated with West Germany, while East Berlin was the "de facto" capital of East Germany. From 13 August 1961 until 9 November 1989, East Berlin was separated from West Berlin by the Berlin Wall. - The Truman Doctrine was an American foreign policy created to counter Soviet geopolitical spread during the Cold War. It was first announced to Congress by President Harry S. Truman on March 12, 1947 and further developed on July 12, 1948 when he pledged to contain Soviet threats to Greece and Turkey. American military force was usually not involved, but Congress appropriated free gifts of financial aid to support the economies and the military of Greece and Turkey. More generally, the Truman doctrine implied American support for other nations threatened by Soviet communism. The Truman Doctrine became the foundation of American foreign policy, and led, in 1949, to the formation of NATO, a military alliance that is still in effect. Historians often use Truman's speech to date the start of the Cold War. Truman told Congress that "it must be the policy of the United States to support free people who are resisting attempted subjugation by armed minorities or by outside pressures." Truman reasoned that because the totalitarian regimes coerced free peoples, they represented a threat to international peace and the national security of the United States. Truman made the plea amid the crisis of the Greek Civil War (194649). He argued that if Greece and Turkey did not receive the aid that they urgently needed, they would inevitably fall to communism with grave consequences throughout the region. Because Turkey and Greece were historic rivals, it was necessary to help both equally even though the threat to Greece was more immediate. Historian Eric Foner argues the Truman Doctrine "set a precedent for American assistance to anticommunist regimes throughout the world, no matter how undemocratic, and for the creation of a set of global military alliances directed against the Soviet Union." - The United Nations Security Council (UNSC) is one of the six principal organs of the United Nations, charged with the maintenance of international peace and security as well as accepting new members to the United Nations and approving any changes to its United Nations Charter. Its powers include the establishment of peacekeeping operations, the establishment of international sanctions, and the authorization of military action through Security Council resolutions; it is the only UN body with the authority to issue binding resolutions to member states. The Security Council held its first session on 17 January 1946. - The Day of German Unity is the national day of Germany, celebrated on 3 October as a public holiday. It commemorates the anniversary of German reunification in 1990, when the goal of a united Germany that originated in the middle of the 19th century, was fulfilled again. Therefore, the name addresses neither the re-union nor the union, but the unity of Germany. The Day of German Unity on 3 October has been the German national holiday since 1990, when the reunification was formally completed. It is a legal holiday for the Federal Republic of Germany. - The Soviet Union, officially the Union of Soviet Socialist Republics (USSR " ) was a socialist state in Eurasia that existed from 1922 to 1991. A union of multiple subnational republics, its government and economy were highly centralized. The Soviet Union was a one-party federation, governed by the Communist Party with Moscow as its capital. - The Locarno Treaties were seven agreements negotiated at Locarno, Switzerland, on 516 October 1925 and formally signed in London on 1 December, in which the First World War Western European Allied powers and the new states of Central and Eastern Europe sought to secure the post-war territorial settlement, and return normalizing relations with defeated Germany (which was, by this time, the Weimar Republic). Ratifications for the Locarno treaties were exchanged in Geneva on 14 September 1926, and on the same day they became effective. The treaties were also registered in the "League of Nations Treaty Series" on the same day.It also stated that Germany would never go to war with the other countries. - Albania (; ), officially the Republic of Albania, is a sovereign state in Southeastern Europe. It has a population of 3.03 million as of 2016. Tirana is the nation's capital and largest city, followed by Durres and Vlore. Albania is located in the south-western part of the Balkan peninsula, bordered by Montenegro to the northwest, Kosovo to the northeast, the Republic of Macedonia to the east, and Greece to the south and southeast. The country has a coastline on the northern shore of the Mediterranean Sea, the Adriatic Sea to the west and the Ionian Sea to the southwest where the Albanian Riviera begins. Albania is less than from Italy, across the Strait of Otranto which connects the Adriatic Sea to the Ionian Sea. - 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 , and has a largely temperate seasonal climate. 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 immigration destination in the world. Germany's capital and largest metropolis is Berlin. Other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart and Dusseldorf. - The Soviet Occupation Zone ("Sovetskaya okkupatsionnaya zona Germanii", "Soviet Occupation Zone of Germany") was the area of central Germany occupied by the Soviet Union from 1945 on, at the end of World War II. On 7 October 1949 the German Democratic Republic (GDR), which became commonly referred to as East Germany, was established in the Soviet Occupation Zone. - Croatia, officially the Republic of Croatia, is a sovereign state between Central Europe, Southeast Europe, and the Mediterranean. Its capital city is Zagreb, which forms one of the country's primary subdivisions, along with its twenty counties. Croatia covers and has diverse, mostly continental and Mediterranean climates. Croatia's Adriatic Sea coast contains more than a thousand islands. The country's population is 4.28million, most of whom are Croats, with the most common religious denomination being Roman Catholicism. - The inner German border (or "deutsch-deutsche Grenze"; initially also "Zonengrenze") was the border between the German Democratic Republic (GDR, East Germany) and the Federal Republic of Germany (FRG, West Germany) from 1949 to 1990. Not including the similar but physically separate Berlin Wall, the border was long and ran from the Baltic Sea to Czechoslovakia. - East Germany, formally the German Democratic Republic or GDR, was an Eastern Bloc state during the Cold War period. From 1949 to 1990, it administered the region of Germany that was occupied by Soviet forces at the end of World War IIthe Soviet Occupation Zone of the Potsdam Agreement, bounded on the east by the OderNeisse line. The Soviet zone surrounded West Berlin, but did not include it; as a result, West Berlin remained outside the jurisdiction of the GDR. The German Democratic Republic was established in the Soviet Zone, while the Federal Republic was established in the three western zones. East Germany was a satellite state of the Soviet Union. Soviet occupation authorities began transferring administrative responsibility to German communist leaders in 1948, and the GDR began to function as a state on 7 October 1949. Soviet forces, however, remained in the country throughout the Cold War. Until 1989, the GDR was governed by the Socialist Unity Party (SED), though other parties nominally participated in its alliance organisation, the National Front of Democratic Germany. - Weimar Republic is an unofficial, historical designation for the German state between 1919 and 1933. The name derives from the city of Weimar, where its constitutional assembly first took place. The official name of the state was still "Deutsches Reich"; it had remained unchanged since 1871. In English the country was usually known simply as Germany. A national assembly was convened in Weimar, where a new constitution for the "Deutsches Reich" was written, and adopted on 11 August 1919. In its fourteen years, the Weimar Republic faced numerous problems, including hyperinflation, political extremism (with paramilitaries both left- and right-wing); and contentious relationships with the victors of the First World War. The people of Germany blamed the Weimar Republic rather than their wartime leaders for the country's defeat and for the humiliating terms of the Treaty of Versailles. However, the Weimar Republic government successfully reformed the currency, unified tax policies, and organized the railway system. Weimar Germany eliminated most of the requirements of the Treaty of Versailles; it never completely met its disarmament requirements, and eventually paid only a small portion of the war reparations (by twice restructuring its debt through the Dawes Plan and the Young Plan). Under the Locarno Treaties, Germany accepted the western borders of the republic, but continued to dispute the Eastern border. - The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union. - The Cold War was a state of political and military tension after World War II between powers in the Eastern Bloc (the Soviet Union and its satellite states) and powers in the Western Bloc (the United States, its NATO allies and others). Historians do not fully agree on the dates, but a common timeframe is the period (the second half of the 20th century) between 1947, the year the Truman Doctrine (a U.S. policy pledging to aid nations threatened by Soviet expansionism) was announced, and 1991, the year the Soviet Union collapsed. - France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans and had a total population of almost 67 million people as of January 2017. It is a unitary semi-presidential republic with the capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse and Bordeaux. - A parliamentary republic is a republic that operates under a parliamentary system of government where the executive branch (the government) derives its legitimacy from and is accountable to the legislature (the parliament). There are a number of variations of parliamentary republics. Most have a clear differentiation between the head of government and the head of state, with the head of government holding real power, much like constitutional monarchies. Some have combined the roles of head of state and head of government, much like presidential systems, but with a dependency upon parliamentary power. - The North Atlantic Treaty Organization (NATO '), also called the North Atlantic Alliance, is an intergovernmental military alliance based on the North Atlantic Treaty which was signed on 4April 1949. The organization constitutes a system of collective defence whereby its member states agree to mutual defence in response to an attack by any external party. Three NATO members are permanent members of the United Nations Security Council with the power to veto and are officially nuclear-weapon states: the United States, France and the United Kingdom. NATO's headquarters are located in Haren, Brussels, Belgium, where the Supreme Allied Commander also resides. Belgium is one of the 28 member states across North America and Europe, the newest of which, Albania and Croatia, joined in April 2009. An additional 22countries participate in NATO's Partnership for Peace program, with 15other countries involved in institutionalized dialogue programmes. The combined military spending of all NATO members constitutes over 70% of the global total. Members' defence spending is supposed to amount to 2% of GDP. - West Germany is the common English name for the Federal Republic of Germany or FRG ( German : Bundesrepublik Deutschland or BRD ) in the period between its creation on 23 May 1949 to German reunification on 3 October 1990 . This period is referred to as the Bonn Republic ( German : Bonner Republik ) by academic historians , an earlier term being the Bonn State ( German : Bonner Staat ) . During this period NATO - aligned West Germany and Warsaw Pact - aligned East Germany were divided by the Inner German border . After 1961 , West Berlin was physically separated from East Berlin as well as from East Germany by the Berlin Wall . This situation ended when East Germany was dissolved and its five states joined the ten states of the Federal Republic of Germany along with the reunified city - state of Berlin . With the reunification of West and East Germany , the Federal Republic of Germany , enlarged now to sixteen states , became known simply as '' Germany '' . The Federal Republic of Germany was established from eleven states formed in the three Allied Zones of occupation held by the United States , the United Kingdom and France ( the '' Western Zones '' ) . Its population grew from roughly 51 million in 1950 to more than 63 million in 1990 . The city of Bonn was its de facto capital city ( Berlin was symbolically named the de jure capital city in the West German Basic Law ) . The fourth Allied occupation zone ( the East Zone , or Ostzone ) was held by the Soviet Union . The parts of this zone lying east of the Oder - Neisse were in fact annexed by the Soviet Union and communist Poland ; the remaining central part around Berlin became the communist German Democratic Republic ( abbreviated GDR ; in German Deutsche Demokratische Republik or DDR ) with its de facto capital in East Berlin . As a result , West Germany had a territory about half the size of the interbellum democratic Weimar Republic . At the onset of the Cold War , Germany ( and , indeed , Europe ) was divided among the Western and Eastern blocs .... - The Oder (Czech, Lower Sorbian and , Upper Sorbian: "Wodra") is a river in Central Europe. It rises in the Czech Republic and flows (generally north- and northwest-ward) through western Poland, later forming of the border between Poland and Germany, part of the OderNeisse line. The river ultimately flows into the Szczecin Lagoon north of Szczecin and then into three branches (the Dziwna, wina and Peene) that empty into the Gulf of Pomerania of the Baltic Sea. - The Berlin Wall was a barrier that divided Berlin from 1961 to 1989. Constructed by the German Democratic Republic (GDR, East Germany), starting on 13 August 1961, the Wall completely cut off (by land) West Berlin from surrounding East Germany and from East Berlin until government officials opened it in November 1989. Its demolition officially began on 13 June 1990 and was completed in 1992. The barrier included guard towers placed along large concrete walls, which circumscribed a wide area (later known as the "death strip") that contained anti-vehicle trenches, "fakir beds" and other defenses. The Eastern Bloc claimed that the Wall was erected to protect its population from fascist elements conspiring to prevent the "will of the people" in building a socialist state in East Germany. In practice, the Wall served to prevent the massive emigration and defection that had marked East Germany and the communist Eastern Bloc during the post-World War II period. - The OderNeisse line is the international border between Germany and Poland. It was drawn at the Potsdam Conference in the aftermath of the Second World War and is primarily delineated along the Oder and Lusatian Neisse rivers in Central Europe, meeting the Baltic Sea to the north, just west of the Polish seaports of Szczecin and winoujcie (German: "Stettin" and "Swinemunde"). All prewar German territory east of the line and within the 1937 German boundaries (23.8% of the former Weimar Republic) were placed under International Law Administrative status, with most of it being made part of newly-Communist Poland. The small remainder, consisting of the territory surrounding the German city of Konigsberg (now renamed Kaliningrad, in honour of Soviet head of state Mikhail Kalinin) in northern East Prussia, was allocated to the Soviet Union (as Kaliningrad Oblast of the Russian SFSR, today the Russian Federation) after the war (pending the final World War II peace treaty for Germany). The vast majority of the native German population in these territories fled, or was killed or expelled by force. The OderNeisse line marked the border between the German Democratic Republic (East Germany) and Poland from 1950 to 1990. East Germany confirmed the border with Poland in 1950, while West Germany, after a period of refusal, finally accepted the border (with reservations) in 1970. In 1990 the newly reunified Germany and the Republic of Poland signed a treaty recognizing it as their border. - The Potsdam Agreement was the agreement between three of the Allies of World War II, United Kingdom, United States, Union of Soviet Socialist Republics, for the military occupation and reconstruction of Germanyreferring to the German Reich with its pre-war 1937 borders including the former eastern territoriesand the entire European theatre of War territory. It also included Germany's demilitarisation, reparations and the prosecution of war criminals. - A republic (from ) is a sovereign state, country, or government which is organized with a form of government in which power resides in elected individuals representing the citizen body and government leaders exercise power according to the rule of law. In modern times, the definition of a republic commonly refers to a government which excludes a monarch. Currently, 147 of the world's 206 sovereign states use the word "republic" as part of their official names; not all of these are republics in the sense of having elected governments, nor do all nations with elected governments use the word "republic" in their names. - The German reunification was the process in 1990 in which the German Democratic Republic (GDR/East Germany) joined the Federal Republic of Germany (FRG/West Germany) to form the reunited nation of Germany, and when Berlin reunited into a single city, as provided by its then Grundgesetz constitution Article 23. The end of the unification process is officially referred to as German unity, celebrated on 3 October (German Unity Day). Following German reunification, Berlin was once again designated as the capital of united Germany.
