The Polish crisis of 1980–1981, associated with the emergence of the Solidarity mass movement in the Polish People's Republic, challenged the rule of the Polish United Workers' Party and Poland's alignment with the Soviet Union. For the first time however, the Kremlin abstained from military intervention, unlike on previous occasions such as the Prague Spring of 1968 and the Hungarian Revolution of 1956, and thus left the Polish leadership under General Wojciech Jaruzelski to impose martial law to deal with the opposition on their own.

Mikhail Andreyevich Suslov was a Soviet statesman during the Cold War. He served as Second Secretary of the Communist Party of the Soviet Union from 1965, and as unofficial chief ideologue of the party until his death in 1982. Suslov was responsible for party democracy and power separation within the Communist Party. His hardline attitude resisting change made him one of the foremost orthodox communist Soviet leaders.
