Which amendment abolished slavery in the United States?

The 13th Amendment is the correct answer because it specifically states that neither slavery nor involuntary servitude shall exist within the United States, except as a punishment for a crime. Ratified in December 1865, this amendment marked a significant legal transformation in American society following the Civil War. It formally abolished slavery, which had been a long-standing institution in the United States, and ensured that no individual could be held in bondage against their will.

The other amendments mentioned serve different purposes: the 14th Amendment addresses citizenship rights and equal protection under the laws, particularly aimed at protecting the rights of formerly enslaved individuals; the 15th Amendment grants African American men the right to vote, prohibiting voting discrimination based on race; and the 19th Amendment extends voting rights to women. Each of these amendments is important in promoting civil rights, but none specifically addresses the abolition of slavery as the 13th Amendment does.
