Which amendment abolished slavery in the United States?

The 13th Amendment is the correct choice as it explicitly abolished slavery in the United States. Ratified in December 1865, this amendment 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 was a crucial step in ensuring freedom and civil rights for all individuals, particularly following the Civil War, which sought to end the institution of slavery.

The other amendments mentioned serve different purposes: the 14th Amendment, ratified in 1868, granted citizenship to all persons born or naturalized in the United States and provided equal protection under the law; the 15th Amendment, ratified in 1870, aimed to protect the right to vote regardless of race, color, or previous condition of servitude; and the 19th Amendment, ratified in 1920, granted women the right to vote. While all these amendments are significant in the broader context of civil rights in the United States, their goals differ from the abolition of slavery established by the 13th Amendment.
