The Emancipation Proclamation (1863)

Lincoln's Emancipation Proclamation freed enslaved people only in Confederate states — not in the border states that remained in the Union. Critics at the time called it a cynical war measure that freed no one Lincoln actually controlled. Defenders argue it transformed the Civil War from a fight to preserve the Union into a moral crusade against slavery, enabling the recruitment of 180,000 Black soldiers and making abolition an irreversible war aim.
