Alexandria Library Sit-In, 1939

In 1939 -- decades before Virginia schools were integrated, and sit-ins emerged as a primary strategy for protesting segregated businesses and public facilities in the South -- Alexandria, Virginia lawyer Samuel Tucker organized a successful sit-in to demonstrate against the Alexandria Library's "whites only" policy. It is believed to be the first sit-in for desegregation in American history.
