The Thirteenth Amendment is one of the most important changes ever made to the United States Constitution. It ended slavery and involuntary servitude throughout the country, except as punishment for a crime after conviction. Ratified in 1865, it marked a turning point after the Civil War and changed the legal meaning of freedom in the United States.

Its words helped transform a nation built partly on slavery into one legally committed to emancipation.

Common Mistakes to Avoid

  • Saying the Emancipation Proclamation ended slavery everywhere is wrong because it applied mainly to areas in rebellion and did not permanently abolish slavery nationwide.
  • Ignoring the exception clause is wrong because the amendment allows involuntary servitude as punishment for a crime after a lawful conviction.
  • Thinking the Thirteenth Amendment only affected the South is wrong because constitutional amendments apply across the entire United States.
  • Treating ratification as the same as congressional passage is wrong because an amendment must also be approved by the required number of states.
