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, except as punishment for a crime, shall exist within the United States or any place subject to their jurisdiction. Ratified in 1865, this amendment effectively abolished slavery throughout the country, marking a significant turning point in American history and civil rights.

The other amendments listed serve different purposes: the 14th Amendment grants citizenship and equal protection under the law to all persons born or naturalized in the U.S., the 15th Amendment prohibits denying the right to vote based on race, color, or previous condition of servitude, and the 19th Amendment guarantees women the right to vote. Each of these amendments addresses important civil rights issues, but none are focused on the abolition of slavery, which is the core function of the 13th Amendment.
