West Germany

"Due to the Russian invasion of Germany, it divided once again since the Cold War started when the two Germanies divided it while one is being transitioned from a fascist military dictatorship into a democracy, and the other one is being tranisitioned to into a communist country."

--Su Ji-Hoon, Brüder Gegen Brüder

Germany (German: West Deutschland, pronounced [ˈvest ˈdɔʏtʃlant]), officially the Federal Republic of Germany (German: Bundesrepublik Deutschland), is a federal parliamentary republic in central-western Europe. During this Cold War era, 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 split into five states, which then 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." This period is referred to as the Bonn Republic (Bonner Republik) by historians, alluding to the interwar Weimar Republic and the post-reunification Berlin Republic.

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"). US and British forces remained in the country throughout the Cold War. Its population grew from roughly 51 million in 1950 to more than 63 million in 1990. The city of Bonn was its (provisional) capital. The fourth Allied occupation zone (the East Zone, or Ostzone) was held by the Soviet Union, bounded to the east by the Oder-Neisse line; and in 1949 this became the socialist German Democratic Republic (abbreviated GDR; in German Deutsche Demokratische Republik or DDR) with its de facto capital in East Berlin. The former parts of Germany east of the Oder-Neisse were separated from 'Germany as a whole' by the Potsdam Agreement of 1945, and then annexed by Poland and the Soviet Union. 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, Europe was divided among the Western and Eastern blocs. Germany was de facto divided into two countries and two special territories, the Saarland and divided Berlin. Initially the Federal Republic of Germany claimed an exclusive mandate for all of Germany, considering itself to be the democratically reorganized continuation of the 1871–1945 German Reich. It took the line that the GDR was an illegally constituted puppet state. Though the GDR did hold regular elections, these were not free and fair. From the West German perspective, the GDR was therefore illegitimate.
