In March 1968, after a wave of student demonstrations defending civic liberties rolled through Poland, the communist authorities of People’s Republic of Poland instigated an anti-Semitic campaign. Both processes affected the Central School of Planning and Statistis (SGPiS), as SGH was known at the time. In response to the brutal suppression of a demonstration by students from University of Warsaw on March 8, on Monday, March 11, a student rally was organised at SGPiS. The rally was attended by rector Wiesław Sadowski, whose words „this rally is legal, because I am taking part in it” went down in history. By joining the students, university employees attempted to ensure safety during the event and – above all – to stop SGPiS students from taking to the streets.
