Legal Question in Civil Rights Law in Maryland

Re: US History

There are 27 amendments. You may be referring to the thirteenth which abolishes slavery. It says:

Section 1. 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.

Section 2. Congress shall have power to enforce this article by appropriate legislation.
