The 14th amendment was adopted in 1868, after the American Civil War, and addresses the equal protection and rights of former slaves. The 14th amendment limits the action of state and local officials. In addition to equal protection under the law to all citizens, the amendment also addresses what is called "due process", which prevents citizens from being illegally deprived of life, liberty, or property.
The full text of the amendment can be found on this U.S. Government Archives website.
