The Thirteenth Amendment
On January 1, 1863, President Abraham Lincoln issued the Emancipation Proclamation. Designed to weaken the Confederacy, it declared that all persons enslaved in a state, or part of a state, then in rebellion against the United States were and would be forever free. The Thirteenth Amendment to the U.S. Constitution, passed by Congress and ratified by the states in 1865, abolished slavery nationwide.
Section 1. Neither slavery nor involuntary servitude except as punishment for a crime whereof the party shall have been duly convicted, shall hereafter exist within the United States or any place subject to their jurisdiction.
