The Emancipation Proclamation took effect on January 1, 1863, a Civil War milestone remembered during America250.
President Abraham Lincoln issued the final proclamation after announcing a preliminary version on September 22, 1862. The order declared enslaved people in areas still rebelling against the United States to be free. It did not apply to loyal slave states or Union-controlled parts of Confederate states, where slavery continued until later constitutional action.
The proclamation changed the war’s stated purpose and authorized Black men to join the Union Army and Navy. Nearly 200,000 African American soldiers and sailors eventually served, strengthening the Union effort and advancing emancipation.
The Thirteenth Amendment, ratified in December 1865, abolished slavery throughout the United States. June 19, commemorated as Juneteenth, marks the 1865 announcement of emancipation in Texas, not the date the proclamation originally took effect.
