The Fourteenth Amendment (Amendment XIV) to the United States Constitution was adopted on July 9, 1868, as one of the Reconstruction Amendments. The amendment addresses citizenship rights and equal protection of the laws, and was proposed in response to issues related to former slaves following the American Civil War. The amendment was bitterly contested, particularly by Southern states, which were forced to ratify it in order for them to regain representation in Congress. The Fourteenth Amendment, particularly its first section, is one of the most litigated parts of the Constitution, forming the basis for landmark decisions such as Roe v. Wade (1973) regarding abortion, Bush v. Gore (2000) regarding the 2000 presidential election, and Obergefell v. Hodges (2015) regarding same-sex marriage. The amendment limits the actions of all state and local officials, including those acting on behalf of such an official.
