The document discusses the origins and history of the Magna Carta from 1215 to 1297. It was initially created to limit the power of the unpopular King John, who faced opposition from his barons and failed attempts to invade France. The barons forced King John to approve the Magna Carta in 1215 to gain more control. After John's death, his son King Henry revised the Magna Carta further in 1216. The version we know today was established in 1297 when King Edward of England revised and codified the statute.
