On February 27, 1960, about 300 college students marched into downtown Nashville to confront Jim Crow segregation. Each of the marchers understood that they belonged to a larger movement of young people. Just three weeks earlier, in Greensboro, N.C., four college students staged a sit-in at the whites-only lunch counter in a Woolworth store. That action desegregated the lunch counter and triggered waves of copycat protests—like the one in Nashville.
