Which amendment abolished slavery in the United States?

The amendment that abolished slavery in the United States is the 13th Amendment. Ratified in 1865, it specifically states that neither slavery nor involuntary servitude, except as punishment for a crime, shall exist within the United States or any place subject to their jurisdiction. This marked a significant turning point in American history, as it legally freed millions of enslaved individuals and laid the groundwork for subsequent civil rights advancements.

The other amendments listed serve different purposes: the 14th Amendment focuses on citizenship rights and equal protection under the law, the 15th Amendment prohibits the denial of voting rights based on race, and the 19th Amendment grants women the right to vote. Each of these amendments plays a crucial role in the framework of American civil rights but does not address the issue of slavery directly like the 13th Amendment does.
