In January 1968, the communist authorities of Poland banned the performance of a play at the Polish Theatre in Warsaw, saying that it was anti-socialist. Student protests followed. On March 8 1968, a 1,500-strong student demonstration at the Warsaw University was attacked by the authorities. Within four days, protests spread to other cities such as Krakow, Lublin, Gliwice, Wroclaw, Gdansk, Poznan and Lodz. The communists organized workers and militia to attack the protesters.
