Federal Republic of Germany

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 historians, an earlier term being the Bonn State (German: Bonner Staat).[4]

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."
