The document summarizes the fall of communism in Eastern Europe from the 1950s through the 1990s. It discusses key events such as Stalin's death in 1953 and the reforms enacted under Khrushchev that allowed for more freedoms. It then covers the Hungarian Revolution of 1956 and Prague Spring protests of 1968 that were crushed by the Soviet Union. Major reforms under Gorbachev in the 1980s, including glasnost and perestroika, weakened Soviet control and led Eastern European nations to demand more freedoms and hold free elections. This resulted in the fall of communist governments across Eastern Europe between 1989-1990 and the reunification of Germany.
