The Wall fell due to both internal pressures within East Germany and the USSR, as well as external pressures from the West. Gorbachev's policies of perestroika and glasnost signaled to West Germany that the Soviet Union would no longer use force to control its satellite states. This abandonment of the Brezhnev Doctrine doomed East Germany. Finally, on July 1, 1990, East and West Germany were reunited under West Germany's existing government structure as the Federal Republic of Germany.
