Which Constitutional Amendment abolished slavery?

The amendment that abolished slavery is the Thirteenth Amendment. Ratified in 1865, this significant piece of legislation specifically states that "neither slavery nor involuntary servitude, except as a punishment for crime, shall exist within the United States." It was a pivotal moment in American history, formally ending the institution of slavery that had persisted since the colonial era.

The other amendments listed serve different purposes in the context of civil rights and governance. The Twelfth Amendment deals with the election of the President and Vice President, the Fourteenth Amendment grants citizenship and equal protection under the law to all persons, and the Fifteenth Amendment prohibits denying the right to vote based on race or color. Each of these amendments plays a crucial role in shaping civil rights and the governance of the United States, but only the Thirteenth Amendment directly addresses the legal status of slavery in the nation.
