Gorbachev’s foreign policy reformsled to the rise of nationalism
Under Khrushchev and Brezhnev, Soviet-controlled states in Eastern Europe were only allowed limited freedom
Gorbachev rejected the Brezhnev doctrine in August 1989, renouncing the Soviet Union’s right to intervene in the affairs of other socialist countries
The new doctrine, named the Sinatra Doctrine, allowed greater freedoms across Eastern European countries
As a result, during October and November 1989, communism fell across Eastern Europe, with new leaders winning democratic elections and peaceful revolutions against Communist rule
Gorbachev allowed these changes to happen, refusing to use Soviet troops against democracy
Revolution in Eastern Europe had implications for the Soviet republics, with nationalists in non-Russian republics hoping to regain their independence.
