violent protest movement.

Explanation:

In 1960, four African American college students staged a nonviolent protest by sitting at a segregated Woolworth's lunch counter in Greensboro, North Carolina. This act sparked a wave of similar sit-in protests across the U.S. to challenge racial segregation in public spaces, launching the sit-in movement. Boycotts (like the Montgomery Bus Boycott) focused on economic refusal, freedom rides involved interstate bus desegregation, and this was a non-violent action.

Answer:

sit-in movement.
