It was New Year’s Day, 1863. For nearly two years, the United States had been at war with itself. Northern and Southern states were battling each other in the Civil War. President Abraham Lincoln was working hard to bring the U.S. back together as one nation.
On that day, he signed a document that would change the course of the war—and lead to freedom for millions of enslaved people. That document was called the Emancipation Proclamation.
