The organisers of the demonstration were arrested; meanwhile the Warsaw branch of the Writers Union, supported by well-known personalities such as Slonimski, Jastrun, Andrzejewksi, Kolakowski and Jasienica protested the decision to close Dziady as Party censorship curtailing creativity. On 8/3/1968 a student protest meeting was brutally broken up by police and paramilitaries. Unrest spread onto the streets of Warsaw and to other Polish universities. The intelligentsia supported the students but the workers, influenced by official propaganda, opposed them. Around 1,200 students were arrested but only a small number were tried and received jail terms. Some were temporarily suspended from their university, Some academics also lost their posts, entire university departments were closed, new academic appointments were made on political grounds not ability, and overall, academic freedom was replaced by repression and suspicion, at least while Gomulka held power in Poland.
