Introduction
Overview
The Bolsheviks seized power in Russia in 1917 and tried to build a state that would transform society. The Soviet Union that emerged became a major world power through industrialisation and war, but its rule also brought repression and immense human cost. Its collapse in 1991 ended a defining political experiment of the twentieth century.
Key forces
- The Soviet state was founded on communist ideology and one-party rule, establishing the Bolsheviks as the sole legitimate political authority from the revolution's earliest days.
- Forced industrialisation under Stalin transformed the USSR into an industrial power at catastrophic human cost, including the collectivisation famine that killed millions.
- Victory in World War Two became the central legitimising myth of Soviet power, achieved through immense sacrifice and used to justify the post-war satellite empire in Eastern Europe.
- The Soviet Union's collapse in 1991 ended a global ideological project and reshaped the international order, leaving unresolved questions of identity, power, and borders that persist today.
