What is the 1314 and 15th amendments?

The 13th Amendment, ratified in 1865, abolished slavery and involuntary servitude in the United States, except as punishment for a crime. The 14th Amendment, ratified in 1868, granted citizenship to all persons born or naturalized in the U.S. and ensured equal protection under the law, fundamentally reshaping civil rights. The 15th Amendment, ratified in 1870, prohibits the federal and state governments from denying a citizen the right to vote based on "race, color, or previous condition of servitude," aiming to secure voting rights for African American men. Together, these amendments significantly advanced civil rights and liberties in the post-Civil War era.
