Which amendment abolished slavery?

The Thirteenth Amendment is the correct answer 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 significant shift in American history, ensuring that neither slavery nor forced labor would be legally permissible in the country.

The First Amendment primarily deals with the freedoms of speech, religion, press, assembly, and petition and does not address issues related to slavery. The Fourteenth Amendment focuses on citizenship rights and equal protection under the law, and while it was a crucial part of the post-Civil War constitutional amendments, it did not directly abolish slavery. The Nineteenth Amendment granted women the right to vote, which is an important civil rights milestone but is unrelated to the abolition of slavery. Thus, the Thirteenth Amendment stands out as the definitive legal instrument for ending the institution of slavery in the United States.
