In the days after February 1, 1960, the sit-ins spread like wildfire throughout the South. Within three months, sit-ins were taking place in more than 55 cities in 13 states.

Students at Historically Black Colleges and Universities (HBCUs) inspired legions of protestors of every race and gender to join the movement. By the end of March 1960, the sit-in movement had spread to more than 55 cities in 13 states.
