Five African-American youths staged America’s first deliberate and planned sit-in at the segregated Alexandria Library on Queen St. on Aug. 21, 1939 — more than two decades before the tactic would become the trademark of the 1960s Civil Rights Movement, according to Historic Alexandria.

The protest had its roots in earlier efforts by attorney Samuel Wilbert Tucker and retired Army Sgt. George Wilson, who on March 17, 1939, had walked through the doors of the whites-only library and requested applications for library cards. Library policy prohibited issuing cards to “persons of the colored race.”
