Which amendment abolished slavery in the United States?

• A. 14th Amendment
• B. 15th Amendment
• C. 13th Amendment
• D. 12th Amendment

Answer: (C)

Ending slavery nationwide comes from the amendment that explicitly outlaws slavery and involuntary servitude in every part of the United States, with a small exception for punishment after a criminal conviction. This constitutional prohibition made emancipation permanent and binding across all states and territories, building on the earlier wartime emancipation but ensuring it would last. The other amendments address different rights: one defines who is a citizen and guarantees equal protection under the law, another protects voting rights regardless of race, and another handles the process for choosing the President and Vice President. None of those abolish slavery, which is why this particular amendment is the one that ended slavery in the United States.
