English: John (24 December 1166 – 18/19 October 1216), also known as John Lackland (Anglo-Norman French: Johan sanz Terre), was King of England from 6 April 1199 until his death. Following the Battle of Bouvines, John lost the duchy of Normandy to Philip II of France, which resulted in the collapse of most of the Angevin Empire and contributed to the subsequent growth in power of the Capetian dynasty during the 13th century. The First Barons' War at the end of John's reign led to the sealing of the Magna Carta, a document sometimes considered to be an early step in the evolution of the constitution of the United Kingdom.
