Excerpt: John (24 December 1166 - 18/19 October 1216), also known as John Lackland (French: Sansterre), was King of England from 6 April 1199 until his death. During John's reign, England lost the duchy of Normandy to King 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.

When war with France broke out again in 1202, John achieved early victories, but shortages of military resources and his treatment of Norman, Breton and Anjou nobles resulted in the collapse of his empire in northern France in 1204. John spent much of the next decade attempting to regain these lands, raising huge revenues, reforming his armed forces and rebuilding continental alliances. John's judicial reforms had a lasting, positive impact on the English common law system, as well as providing an additional source of
