THE THIRTEENTH AMENDMENT. (freed the slaves) The Emancipation Proclamation was meant to free the slaves in the Confederate States, but the Confederate government did not recognize the Union President freeing their slaves. The Thirteenth Amendment, however, freed the slaves everywhere in the United States.
The document that President Abraham Lincoln used to free the slaves was called the Emancipation Proclamation. It freed slaves in the rebelling Southern states only, not border states. They were freed later. As Lincoln had no authority to free slaves, this was a war measure. The results were that slaves in areas captured by Union forces were freed.
