What amendment to the U.S. Constitution abolished slavery in the United States?

The 13th Amendment to the U.S. Constitution is significant because it formally abolished slavery and involuntary servitude in the United States, except as punishment for a crime. Ratified on December 6, 1865, this amendment was a critical step in the nation's transition following the Civil War, marking a foundational change in American society by ensuring that no person could be owned or forced into labor against their will. This action addressed and sought to rectify the injustices of slavery and was an essential part of the Reconstruction era reforms aimed at integrating formerly enslaved people into American civic life. The other amendments listed pertain to different issues: the 12th addresses the electoral process, the 14th focuses on citizenship and equal protection under the law, and the 15th concerns voting rights regardless of race.
