14th Amendment

The Fourteenth Amendment to the United States Constitution was adopted on July 9, 1868, and addresses citizenship rights and equal protection under the law. The amendment's first section, which includes the Citizenship Clause, Privileges or Immunities Clause, Due Process Clause, and Equal Protection Clause, is one of the most litigated parts of the Constitution, forming the basis for landmark Supreme Court decisions on racial segregation, interracial marriage, abortion, and same-sex marriage. The amendment limits the actions of state and local officials and has been interpreted to make most of the Bill of Rights applicable to the states as well as to recognize substantive and procedural requirements that state laws must satisfy.learn more on wikipedia
