Which amendment abolished slavery in the United States?

The 13th Amendment to the United States Constitution, ratified in 1865, is the landmark piece of legislation that abolished slavery and involuntary servitude, except as punishment for a crime. This amendment was a significant outcome of the Civil War and reflected the growing abolitionist sentiments in the country. By officially outlawing slavery, it marked a fundamental shift in American society and laid the groundwork for future civil rights developments.

In contrast, the 14th Amendment addresses citizenship rights and equal protection under the law, the 15th Amendment focuses on voting rights regardless of race, and the 19th Amendment grants women the right to vote. Each of these amendments plays an important role in the broader context of civil rights in the United States, but it is the 13th Amendment that specifically and directly ended the institution of slavery.
