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 communist regime 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 (branded "anti-Zionist") 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.
