Answer:
Destalinization
Step-by-step explanation:
The Polish and the Hungarian people were not so fond of the Soviet Union, its policies, and its actions in their respective countries. When Khrushchev came to power, he made his famous secret six hour speech. The speech was mostly based around denouncing the things that happened during the reign of Stalin. This led to lot anger and resentment in Poland and Hungary, so the people got out on the streets to protests against it and throw away the Soviet control. Despite both rebellions being put in order eventually, both countries managed to gain some rights, and got larger freedom and autonomy when it came to making decisions, though they still had to remain loyal to the Warsaw Pact and be friendly toward the Soviet Union.
