Poland transitioned to communism after World War II, influenced by the Soviet Union’s expansion of its ideology across Eastern Europe. In 1945, with the Yalta Conference agreements, the atmosphere of post-war Europe allowed for the establishment of a communist government in Poland. The Soviet-backed Polish Workers' Party emerged as the ruling authority, which led to significant political, social, and economic changes in the country. This transition entailed the nationalization of key industries, collectivization of agriculture, and strict government control over many aspects of life, reflecting the broader trend of Soviet domination in Eastern Europe during the Cold War.
