Which movement emphasized the right to protest for free speech at universities?

The Free Speech Movement is the correct answer because it specifically emerged in the early 1960s at the University of California, Berkeley. This movement sought to defend the right of students to engage in political activities and free speech on campus, marking a significant moment in the struggle for civil liberties in academic environments. It was fueled by a desire to challenge the restrictions placed on student political activism and to advocate for the right to express dissent against political decisions, particularly in relation to civil rights and the Vietnam War.

This movement was foundational in shaping the landscape of student activism and raised awareness about the importance of free speech within educational institutions, inspiring similar movements across the country. Thus, its focus on the right to protest for free speech aligns directly with the premise of the question.
