The sit-ins of the American civil rights movement were extraordinary acts of dissent in an age marked by protest. By sitting in at "whites only" lunch counters, libraries, beaches, swimming pools, skating rinks, and churches, young African Americans and their allies put their lives on the line, fully aware that their actions would almost inevitably incite hateful, violent responses from entrenched and increasingly desperate white segregationists. And yet they did so in great numbers: most estimates suggest that in 1960 alone more than seventy thousand young people participated in sit-ins across the American South and more than three thousand were arrested. The simplicity and purity of the act of sitting in, coupled with the dignity and grace exhibited by participants, lent to the sit-in movement's sanctity and peaceful power.
