Cold WarThe Cold War was a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term cold war is used because there was no large-scale fighting directly between the two superpowers, but they each supported opposing sides in major regional conflicts known as proxy wars. The conflict was based on the ideological and geopolitical struggle for global influence by these two superpowers, following their roles as the Allies of World War II that led to victory against Nazi Germany and Imperial Japan in 1945.
Berlin WallThe Berlin Wall (Berliner Mauer, bɛʁˌliːnɐ ˈmaʊ̯ɐ) was a guarded concrete barrier that encircled West Berlin of the Federal Republic of Germany (FRG) from 1961 to 1989, separating it from East Berlin and the German Democratic Republic (GDR). Construction of the Berlin Wall was commenced by the government of the GDR on 13 August 1961. It included guard towers placed along large concrete walls, accompanied by a wide area (later known as the "death strip") that contained anti-vehicle trenches, beds of nails and other defenses.
German reunificationGerman reunification (Deutsche Wiedervereinigung) was the process of re-establishing Germany as a single full sovereign state, which took place between 9 November 1989 and 15 March 1991. The day of 3 October 1990 when the "Unification Treaty" entered into force dissolving the German Democratic Republic (GDR; Deutsche Demokratische Republik, DDR, or East Germany) and integrating its recently re-established constituent federated states into the Federal Republic of Germany (FRG; Bundesrepublik Deutschland, BRD, or West Germany) to form present-day Germany, has been chosen as the customary German Unity Day (Tag der deutschen Einheit) and has thereafter been celebrated each year as a national holiday in Germany since 1991.
Eastern BlocThe Eastern Bloc, also known as the Communist Bloc, the Socialist Bloc, and the Soviet Bloc, was the coalition of communist states of Central and Eastern Europe, East Asia, Southeast Asia, Africa, and Latin America under the power of the Soviet Union that existed during the Cold War (1947–1991). These states followed the ideology of Marxism–Leninism, in opposition to the capitalist Western Bloc.
Soviet UnionThe Soviet Union, officially the Union of Soviet Socialist Republics (USSR), was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR.

With an area of 29,480 square kilometres (11,382 square miles) and a population of 2.5 million residents, it is the fifth-largest German state by area and the tenth-most populous.
West GermanyWest Germany (Westdeutschland) is the colloquial English term used to indicate the Federal Republic of Germany (FRG; Bundesrepublik Deutschland ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant) between its formation on 23 May 1949 and the German reunification through the accession of East Germany on 3 October 1990. During the Cold War, the western portion of Germany and the associated territory of West Berlin were parts of the Western Bloc.
World War IIWorld War II or the Second World War, often abbreviated as WWII or WW2, was a global conflict lasting from 1939 to 1945. The vast majority of the world's countries, including all of the great powers, fought as part of two opposing military alliances: the Allies and the Axis. Many participants threw their economic, industrial, and scientific capabilities behind this total war, blurring the distinction between civilian and military resources.
