The actions of four african american college students at a lunch counter in 1960 started a sit-in movement. boycott movement. freedom ride movement. violent protest movement.

The correct answer is sit-in movement.

The four African American college students staged a sit-in at the Woolworths lunch counter in Greensboro North Carolina. The goal of this sit-in was to protest the Woolworth policy of racial segregation within their store. Even after all four men were arrested, hundreds of African American college students continued to take their place at this lunch counter to continue the fight to desegregate this facility. This form of nonviolent protest would become increasingly popular throughout the 1960's.
