Why was the Magna Carta important for the middle ages?

The Magna Carta, signed in 1215, was crucial for the Middle Ages as it established the principle that everyone, including the king, was subject to the law. It laid the groundwork for the development of constitutional governance and individual rights, which challenged the absolute power of monarchs. By asserting the rights of nobles and limiting royal authority, it inspired future democratic movements and legal frameworks, influencing the evolution of modern democracy. Its legacy continues to resonate in contemporary legal and political systems.
