At the end of the Second World War the city was occupied by the Allies and divided into two parts: West Berlin, comprising the American, British, and French sectors, later a state of the Federal Republic of Germany despite forming an enclave within the German Democratic Republic; and East Berlin, the sector of the city occupied by the Soviet Union and later capital of the German Democratic Republic. Between 1961 and 1989 the Berlin Wall separated the two parts, which were reunited in 1990; occupation formally ended in 1994
