Which amendment to the Constitution abolished slavery?

The 13th Amendment to the United States Constitution abolished slavery and involuntary servitude, except as a punishment for a crime. Ratified in December 1865, this amendment marked a significant moment in American history, as it legally freed all enslaved individuals in the United States following the Civil War. It represents a core principle of human rights and civil liberties by ensuring that slavery would no longer be tolerated in any form within the country.

The other amendments mentioned—such as the 14th Amendment, which granted citizenship and equal protection under the law to all persons born or naturalized in the U.S., the 15th Amendment, which gave African American men the right to vote, and the 12th Amendment, which revised the procedure for electing the President and Vice President—address different issues related to civil rights and governmental structure but do not pertain to the abolition of slavery.
