Stalin's policies refer to the series of political, economic, and social strategies implemented by Joseph Stalin, the leader of the Soviet Union from the mid-1920s until his death in 1953. These policies aimed at transforming the Soviet Union into a major industrial power, consolidating state control over all aspects of life, and spreading communist ideology throughout Eastern Europe. The aggressive nature of these policies, particularly in the context of Soviet expansion, shaped the post-World War II landscape in Eastern Europe, where Stalin sought to establish satellite states and secure Soviet influence.
