The ancient document that outlined the rights of citizens and is fundamental to democratic societies is the Magna Carta, signed in 1215. This charter was a pivotal legal document that established the principle that everyone, including the king, was subject to the law. It provided certain rights to individuals, such as the right to a fair trial and protection from unlawful imprisonment. The Magna Carta laid the groundwork for modern democracy and constitutional law, influencing various documents and declarations around the world, including the U.S. Constitution and the Universal Declaration of Human Rights.
