John, King of England

[close] John (1166 – 1216), also known as John Lackland (Norman French: Johan sanz Terre), was King of England from 6 April 1199 until his death in 1216. John lost the Duchy of Normandy to King Philip II of France, resulting in the collapse of most of the Angevin Empire and contributing to the subsequent growth in power of the Capetian dynasty during the 13th century. The baronial revolt at the end of John's reign led to the sealing of Magna Carta.

Contemporary chroniclers were mostly critical of John's performance as king, and his reign has since been the subject of significant debate and periodic revision by historians from the 16th century onwards. Historian Jim Bradbury has summarised the current historical opinion of John's positive qualities, observing that John is today usually considered a "hard-working administrator, an able man, an able general". Nonetheless, modern historians agree that he also had many faults as king, including what historian Ralph Turner describes as "distasteful, even dangerous personality traits", such as pettiness, spitefulness, and cruelty.
