The "Civil War Amendments" refer to three amendments to the United States Constitution that were adopted in the aftermath of the American Civil War. These amendments aimed to establish and protect the rights of newly freed African Americans and to ensure equality under the law. The three amendments are the 13th Amendment, which abolished slavery; the 14th Amendment, which granted citizenship and equal protection under the law; and the 15th Amendment, which aimed to protect the voting rights of African American men. Together, these amendments significantly reshaped American society and legal standards.
