The two amendments that guaranteed the rights and freedoms of African Americans post-Civil War are the 14th Amendment and the 15th Amendment.
- The 14th Amendment granted citizenship to all persons born or naturalized in the United States and ensured equal protection under the law.
- The 15th Amendment granted African American men the right to vote by prohibiting the federal and state governments from denying a citizen the right to vote based on "race, color, or previous condition of servitude."
