Communist governments in Eastern Europe refer to the political regimes that emerged in various countries in the region after World War II, characterized by one-party rule, state control of the economy, and adherence to Marxist-Leninist ideology. These governments were often installed or supported by the Soviet Union, leading to a centralized authority that suppressed political dissent and limited individual freedoms. The experience of these regimes varied across nations, but they commonly faced challenges related to economic inefficiency and popular discontent.
