Lincoln issues the Emancipation Proclamation, freeing enslaved people in rebel states
The Emancipation Proclamation took effect on January 1, 1863, when President Lincoln declared enslaved people in rebelling Confederate states legally free. Between 25,000 and 75,000 were liberated immediately in Union-held areas, with millions more as federal forces advanced. It reframed the Civil War as a fight against slavery and opened the path to the 13th Amendment.
