The Magna Carta, signed in 1215 by King John of England, is a historic document that granted civil liberties to the people. It was created in response to the king's heavy taxation and arbitrary rule, establishing the principle that the monarch's power is not absolute. The Magna Carta assured rights such as due process, fair trials, and protection from unlawful imprisonment, laying the groundwork for the development of constitutional law. Its legacy continues to influence legal systems and democratic governance worldwide, serving as a symbol of individual rights and the rule of law against tyranny over the centuries.
