What was the cause of the Siege of Rochester?

The Siege of Rochester in 1215 was primarily caused by the conflict between King John of England and rebellious barons who opposed his rule. The barons had taken control of Rochester Castle as part of their revolt against the king's heavy taxation and perceived abuses of power. In response, King John sought to reclaim the castle to reassert his authority, leading to the siege. The conflict was part of the larger struggle during the First Barons' War, which ultimately resulted in the Magna Carta.
