There are iconic episodes of the anti-Franco struggle: the workers' movement of Baix Llobregat (from the Siemens strike in 1946 to the general strike thirty years later), the flag hung during the enthronement of the Virgin of Montserrat in 1947, the tram strike of 195. Among these episodes we would place The defenestration of a bust of General Franco and the Spanish flag from a window of the historic building of the University of Barcelona (UB) led by some 150 students who, after an assembly in the Auditorium, had occupied the rectorate on January 17, 1969.
