Final answer:
Polish reforms under Khrushchev took place in 1956, involving agricultural decollectivization, fewer Soviet advisors, and more religious freedom.
Step-by-step explanation:
The Polish reforms under Khrushchev occurred in 1956 after the Poznan riots in June and Gomułka's rise to leadership in October. Alarmed by the potential spread of anti-Soviet sentiment, Khrushchev agreed to reforms following reassurances from Gomułka. These reforms included the end of the collectivization of agriculture, the expulsion of Soviet advisers, the release of political prisoners, and increased liberties for the Roman Catholic Church. It was a pivotal event reflecting the complexities of the Soviet satellite states during the Cold War.
The "Polish October" marked a period of relative political liberalization and autonomy within the Eastern Bloc. Gomułka's leadership aimed at national Communism, seeking greater independence from Soviet influence while remaining within the socialist framework.
