Which amendment abolished slavery in the United States?

The 13th Amendment is the correct choice because it specifically abolished slavery and involuntary servitude in the United States, except as punishment for a crime. Ratified on December 6, 1865, this amendment marked a pivotal moment in American history, ensuring that the practice of slavery was officially illegal nationwide.

The other amendments listed focus on different aspects of civil rights and liberties, but they do not address the issue of slavery directly. The 14th Amendment deals primarily with citizenship rights and equal protection under the laws, while the 15th Amendment provides for voting rights regardless of race, color, or previous condition of servitude. The 19th Amendment grants women the right to vote. While all these amendments contribute to the broader framework of civil rights, the specific action of abolishing slavery was solely the function of the 13th Amendment.
