The Polish 1968 political crisis, also known in Poland as March 1968, Students' March, or March events, was a series of major student, intellectual and other protests against the ruling Polish United Workers' Party of the Polish People's Republic. The crisis led to the suppression of student strikes by security forces in all major academic centres across the country and the subsequent repression of the Polish dissident movement. It was also accompanied by mass emigration following an antisemitic campaign waged by the minister of internal affairs, General Mieczysław Moczar, with the approval of First Secretary Władysław Gomułka of the Polish United Workers' Party (PZPR). The protests overlapped with the events of the Prague Spring in neighboring Czechoslovakia – raising new hopes of democratic reforms among the intelligentsia. The Czechoslovak unrest culminated in the Warsaw Pact invasion of Czechoslovakia on 20 August 1968.

The Polish United Workers' Party, commonly abbreviated to PZPR, was the communist party which ruled the Polish People's Republic as a one-party state from 1948 to 1989. The PZPR had led two other legally permitted subordinate minor parties together as the Front of National Unity and later Patriotic Movement for National Rebirth. Ideologically, it was based on the theories of Marxism-Leninism, with a strong emphasis on left-wing nationalism. The Polish United Workers' Party had total control over public institutions in the country as well as the Polish People's Army, the UB and SB security agencies, the Citizens' Militia (MO) police force and the media.
