Free Speech Movement

The Free Speech Movement was a student protest which began on the campus of the University of California, Berkeley in 1964 under the informal leadership of student Mario Savio and others. In protests unprecedented at the time, students demanded that the university administration lift a ban on on-campus political activities and recognize the students' right to free speech and academic freedom. The Free Speech Movement is often cited as a starting point for the many student protest movements of the 1960s and early 1970s.
