Which amendment abolished slavery in the United States?

The 13th Amendment to the United States Constitution is the landmark amendment that abolished slavery in the United States. Ratified in December 1865, it explicitly states that neither slavery nor involuntary servitude, except as punishment for a crime, shall exist within the United States or in any place subject to its jurisdiction. This amendment marked a significant turning point in American history, as it formally ended the institution of slavery that had existed for centuries and aimed to begin the process of integrating formerly enslaved individuals into society as free citizens.

In contrast, the other amendments listed address different civil rights issues. The 15th Amendment guarantees African American men the right to vote, the 19th Amendment grants women the right to vote, and the 24th Amendment prohibits poll taxes in federal elections. While each of these amendments plays a crucial role in advancing civil rights, only the 13th Amendment directly pertains to the abolition of slavery.
