Who signed the Emancipation Proclamation that took effect on January 1, 1863?

Abraham Lincoln signed the Emancipation Proclamation, which took effect on January 1, 1863.

Lincoln issued the preliminary proclamation on September 22, 1862, after the Union victory at Antietam. The final document declared enslaved people in areas still in rebellion against the United States to be free. It did not apply to the loyal border states or to Confederate areas already occupied by Union forces, because the measure was framed as a wartime action against the rebellion.

The proclamation changed the Civil War’s purpose in international and moral terms and authorized Black men to serve in the Union Army and Navy. Nearly 200,000 Black soldiers and sailors ultimately served the Union cause.

The Emancipation Proclamation did not itself abolish slavery everywhere in the United States. The Thirteenth Amendment, ratified in December 1865, abolished slavery and involuntary servitude except as punishment for crime. Lincoln’s proclamation remains a landmark presidential act associated with the Civil War and emancipation.
