What happened
President Abraham Lincoln signed the Emancipation Proclamation on January 1, 1863, declaring free all enslaved people held within the states then in rebellion against the Union. The order did not apply to enslaved people in the border states that had remained loyal to the Union, nor to Confederate areas already under Union military control, meaning it freed no one directly at the moment it was signed and relied on advancing Union armies to make it real. Pastor John C. Gibbs of Philadelphia's First African Presbyterian Church, reacting to the news, told his congregation that the proclamation meant humanity must now be free. The proclamation formally redefined the purpose of the Civil War for the Union side, adding the end of slavery to the preservation of the union as a war aim, and it opened the way for roughly 200,000 Black soldiers and sailors to serve in Union forces before the war's end.
Why it matters
The Emancipation Proclamation transformed a war fought to preserve the union into a war that would also end slavery, but it left the institution's legal survival dependent on a Union military victory rather than settling it directly, which is why Lincoln and Congress moved afterward to pass the Thirteenth Amendment to guarantee abolition beyond the reach of any future court or peace settlement.
How we know
The Smithsonian's National Museum of African American History and Culture holds and interprets the proclamation and contemporary reactions to it, including period sermons and newspaper accounts documenting how Black communities in the North received the news in January 1863.
