The concept of human rights dates back to antiquity. One can find reference to rights in many national documents. The first reference of personal liberties is found in the Magna Carta of 1215 in England. Other notable references prior to the 19th century are the 1776 Virginia Declaration of Rights and the 1789 French Declaration of the Rights of Man and of the Citizen. The institutionalization of human rights in national documents penetrated into the international system at the end of the 18th century.
