Emancipation Day in Washington, D.C.
Congress passed the Compensated Emancipation Act to end slavery in the District of Columbia and President Abraham Lincoln signed the bill into law on April 16, 1862. Three years later, after the Civil War ended and after the 1865 ratification of the Thirteenth Amendment to the Constitution officially abolishing slavery nationwide, African Americans in the District began to celebrate April 16 as a holiday.
