The significance of the Magna Carta in the evolution of political rights lies in its establishment of the principle that no one, including the monarch, is above the law. Signed in 1215, this document laid the groundwork for individual liberties and the concept of due process. It introduced limitations on governmental power, influencing later constitutional developments, including the English Bill of Rights and the U.S. Constitution. The Magna Carta's legacy persists today as a symbol of the ongoing struggle for human rights, accountability, and the rule of law in democratic societies.
