How did the Soviets influence the political situation in Poland at the end of world war 2?

At the end of World War II, the Soviets established significant influence over Poland by installing a communist government aligned with Moscow, effectively undermining the pre-war democratic government. The Yalta Conference in 1945 resulted in agreements that favored Soviet control in Eastern Europe, leading to the imposition of a socialist regime in Poland. This political shift was marked by the suppression of opposition, including the elimination of non-communist parties, and the establishment of a security apparatus to maintain Soviet dominance in the region. The result was a long-lasting impact on Poland's political landscape, contributing to decades of authoritarian rule.
