Introduction
Key forces
- Soviet economic stagnation under Brezhnev created the structural conditions for crisis, but the system might have continued indefinitely without the pressures released by Gorbachev's reforms.
- Glasnost (openness) undermined the Communist Party's ideological authority by allowing public acknowledgment of the system's failures — especially Chernobyl.
- Nationalist movements in the Soviet republics transformed what Gorbachev intended as a reformed union into a dissolution of the union itself.
- The failed August 1991 coup destroyed the last institutional basis for preserving the Soviet state, accelerating recognition of republican independence.
