Marian Anderson: the Lincoln Memorial Concert is a 1939 documentary film which documents a concert performance by African American opera singer Marian Anderson after the Daughters of the American Revolution (DAR) had her barred from singing in Washington D.C.'s Constitution Hall because she was black. The concert, which was held on Easter, was attended by some 75,000 fans. In 2001 the United States Library of Congress deemed the film "culturally significant" and selected it for preservation in the National Film Registry.
