His titles included King of Ireland 1177, Count of Mortain 1189, Earl of Gloucester. John succeeded his brother Richard I as King in 1199. In 1215 he put his seal on the Magna Carta (Great Charter). The Magna Carta is the foundation of English Constitutional law and liberties and placed the King, like the subjects he ruled, subject to the rule of law. He is Interred in Worcester Cathedral.
