which amendment ended slavery

The amendment that ended slavery in the United States is the Thirteenth Amendment. It was ratified on December 6, 1865, and it abolished slavery and involuntary servitude, except as punishment for a crime where the person has been duly convicted. The full text of Section 1 states: "Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction." The amendment also grants Congress the power to enforce this article through appropriate legislation. The Thirteenth Amendment marked the constitutional end of slavery in the U.S. after the Civil War.
