On February 1, 1960 four African American college students sat at the "whites only" lunch table in Greensboro, North Carolina and they didn't get up and move until it closed. The next day they did the same but with more people. These were known as sit-ins.
Student Nonviolent Coordinating Committee, or SNCC, or "snick" was an organization to allow anyone properly dressed or well-behaved to be served and sit at the lunch tables.
One day six African Americans and seven whites all went in a bus to New Orleans, Louisiana and two were beat up and one arrested for using the wrong restroom. In Alabama a bus was set on fire with people in it and the police just stood by and watched. So they decided to put the rides to an end.
