Arguably the most well-known 19th century anti-slavery and equal rights activist, Douglass spent considerable time in Philadelphia and was well connected in the African American community, as well as among white Republicans and the Union League. Douglass work with Philadelphians on black troop recruitment and his name appears on the “Men of Color of Philadelphia” recruitment poster. As a leader in the National Equal Rights League, Douglass worked with Catto to extend voting and citizenship rights to black men. Douglass was among the black leaders recognized by the Union League for their success in 1869. A Pennsylvania historical marker marks the secret meeting between Frederick Douglass and John Brown on West Washington Street, behind South Gate Mall, in Chambersburg, PA.
