Which amendment abolished slavery in the United States?

The 13th Amendment abolished slavery in the United States, making it a significant turning point in American history. Ratified in December 1865, it formally enacted the prohibition of slavery and involuntary servitude, except as punishment for a crime. This was a crucial step in the Reconstruction era and aimed to integrate formerly enslaved people into society as free citizens.

The other amendments mentioned serve different purposes; the 12th Amendment deals with the election of the President and Vice President, the 14th Amendment addresses citizenship rights and equal protection under the law, and the 15th Amendment focuses on voting rights regardless of race or color. Each of these amendments plays an important role in defining civil rights and liberties in the United States, but none addressed the issue of slavery as directly as the 13th Amendment.
