Ronald Martin, Robert Patterson and Mark Martin sit at a whites-only lunch counter in Greensboro, North Carolina, on February 2, 1960. A day earlier, four African-American college students made history when they sat at the same Woolsworth's counter. Service never came for the "Greensboro Four," as they came to be known, and their peaceful demonstration drew national attention and sparked more sit-ins in Southern cities.

Dion Diamond is harassed during a sit-in at the Cherrydale Drug Fair in Arlington, Virginia. He was part of a small group called the Non-Violent Action Group. Some people threw lit cigarettes at group members, while others kicked them. The two-week protests in June 1960 led to the integration of restaurants in Arlington. Restaurants soon followed in nearby Alexandria and Fairfax.
