The 14th Amendment to the United States Constitution is ratified, guaranteeing African Americans full citizenship and all persons in the United States due process of law. The Fourteenth Amendment 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 the states of the defeated Confederacy, which were forced to ratify it in order to regain representation in Congress. The amendment, particularly its first section, is one of the most litigated parts of the Constitution, forming the basis for landmark decisions such as Brown v. Board of Education (1954) regarding racial segregation, 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.

Carbon is a chemical element with symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. It belongs to group 14 of the periodic table. Three isotopes occur naturally, 12C and 13C being stable, while 14C is a radionuclide, decaying with a half-life of about 5,730 years.
