Here’s a panel discussion at the National Archives on life in the District of Columbia and the emancipation of its slaves.
From the video’s description: “What was 19th-century life like for enslaved and free African Americans in Washington, DC? What was the impact of DC Emancipation in and around the city? A distinguished panel discusses these topics as well as how the assassination of President Lincoln was observed after the Civil War. John Franklin of the National Museum of African American History and Culture moderates Elizabeth Clark-Lewis, Howard University; George Musgrove, UMBC; and Chris Myers, Washington History. Presented in partnership with DC City Government and NMAAHC.”
