Dissolution of the Soviet Union
The 1991 breakup of the Soviet Union into 15 independent states, ending its existence as a federal state and a Cold War superpower.
Belavezha Accords: An agreement signed by Russia, Ukraine, and Belarus on December 8, 1991, declaring that the Soviet Union had ceased to exist. Its signatories formally declared the Union’s end and created the Commonwealth of Independent States.
Perestroika: Mikhail Gorbachev’s program of economic restructuring in the Soviet Union during the 1980s. Its limited reforms disrupted established controls without resolving the economy’s deep problems.
Post-Soviet states: The fifteen independent countries that emerged from the Soviet Union after 1991. Each former union republic became a successor state with its own political trajectory.
Mikhail Gorbachev: The final leader of the Soviet Union, whose reforms loosened political controls and reshaped relations with the West. His reforms and resistance to force changed the conditions under which the republics pursued independence.
Dissolution of Czechoslovakia: The peaceful division of Czechoslovakia into the Czech Republic and Slovakia on January 1, 1993. It was a negotiated breakup of a multinational federation, unlike the Soviet Union’s broader crisis and conflicts.
August Coup: A failed coup attempt by Communist hardliners against Soviet leader Mikhail Gorbachev in August 1991. The coup weakened the central government and accelerated republics’ declarations of independence.
Glasnost: A policy of greater openness in public debate and media under Mikhail Gorbachev. Greater openness exposed past abuses and encouraged criticism of Soviet rule.
Russian Federation: The state that emerged as the Soviet Union’s largest successor, retaining its United Nations Security Council seat. Russia inherited the central role in Soviet diplomacy, military affairs, and international representation.
Boris Yeltsin: The first president of the Russian Federation and a leading opponent of the 1991 coup attempt. He challenged Soviet authority from the Russian republic and signed the Belavezha Accords.
Breakup of Yugoslavia: The disintegration of Yugoslavia during the 1990s into several independent states amid wars and political crises. Both were socialist federations, but Yugoslavia’s dissolution involved far more sustained interstate warfare.
