"The Magna Carta" by Anonymous is a royal charter sealed in 1215. When rebel barons forced King John of England to limit royal power and protect their rights, they created a document that would become one of history's most influential legal texts. Though initially annulled and historically misunderstood, this medieval agreement between monarch and nobility evolved into a powerful symbol of liberty, shaping constitutional thought across centuries and continents, from England's Parliament to America's founding documents.
