Behind the Iron Curtain, in Poland, artist and theater director Tadeusz Kantor staged the first happenings starting in 1965. In the second half of 1970s painter and performer Krzysztof Jung ran the Repassage gallery, which promoted performance art in Poland. Also, in the second half of the 1980s, a student-based happening movement Orange Alternative founded by Major Waldemar Fydrych became known for its much attended happenings (over 10 thousand participants at one time) aimed against the military regime led by General Jaruzelski and the fear blocking the Polish society ever since the Martial Law had been imposed in December 1981.
