The Thirteenth, Fourteenth, and Fifteenth Amendments all secured rights for African Americans.
- The Thirteenth Amendment abolished slavery.
- The Fourteenth Amendment granted citizenship and equal protection under the law.
- The Fifteenth Amendment specifically prohibited the denial of the right to vote based on race, color, or previous condition of servitude.
While these amendments were significant steps toward civil rights, they faced considerable resistance and were enacted during the Reconstruction era following the Civil War, not during the war itself.
