The Greensboro sit-ins were a series of nonviolent protests in February to July 1960, primarily in the Woolworth store—now the International Civil Rights Center and Museum—in Greensboro, North Carolina, which led to the F. W. Woolworth Company department store chain removing its policy of racial segregation in the Southern United States. While not the first sit-in of the civil rights movement, the Greensboro sit-ins were an instrumental action, and also the best-known sit-ins of the civil rights movement. They are considered a catalyst to the subsequent sit-in movement, in which 70,000 people participated. This sit-in was a contributing factor in the formation of the Student Nonviolent Coordinating Committee (SNCC).
