The Magna Carta, signed in 1215, played a critical role in shaping modern democracy by limiting the powers of the king and establishing the principle that everyone, including the monarch, is subject to the law. This foundational document introduced concepts such as the right to a fair trial and due process, signaling a shift toward governance through consent and accountability. Its legacy influenced later democratic movements and documents, especially in England and the United States, as it inspired constitutionalism and the protection of individual rights. The Magna Carta is often seen as a symbol of the fight against tyranny and the promotion of justice.
