Henry III (1 October 1207 – 16 November 1272), also known as Henry of Winchester, was King of England, Lord of Ireland and Duke of Aquitaine from 1216 until his death in 1272. The son of John, King of England, and Isabella of Angoulême, Henry acceded to the throne when he was only nine in the middle of the First Barons' War. Cardinal Guala Bicchieri declared the war against the rebel barons to be a religious crusade and Henry's forces, led by William Marshal, defeated the rebels at the battles of Lincoln and Sandwich in 1217. Henry promised to abide by the Great Charter of 1225, a later version of Magna Carta (1215), which limited royal power and protected the rights of the major barons. Henry's early reign was dominated first by William Marshal, and after his death in 1219 by the magnate Hubert de Burgh, Earl of Kent. In 1230 the King attempted to reconquer the provinces of France that had once belonged to his father, but the invasion was a debacle. A revolt led by William Marshal's son Richard broke out in 1232, ending in a peace settlement negotiated by the Catholic Church.
Following the revolt, Henry ruled England personally, rather than governing through senior ministers. He travelled less than previous monarchs, investing heavily in a handful of his favourite palaces and castles. He married Eleanor of Provence, with whom he had five children. Henry was known for his piety, holding lavish religious ceremonies and giving generously to charities; the King was particularly devoted to the figure of Edward the Confessor, whom he adopted as his patron saint. He extracted huge sums of money from the Jews in England, ultimately crippling their ability to do business. As attitudes towards the Jews hardened, he later introduced the Statute of Jewry, which attempted to segregate the Jewish community from the English populace. In a fresh attempt to reclaim his family's lands in France, he invaded Poitou in 1242, leading to the disastrous Battle of Taillebourg. After this, Henry relied on diplomacy, cultivating an alliance with Frederick II, Holy Roman Emperor. Henry supported his brother Richard of Cornwall in his successful bid to become King of the Romans in 1256, but was unable to place his own son Edmund Crouchback on the throne of Sicily, despite investing large amounts of money. He planned to go on crusade to the Levant, but was prevented from doing so by rebellions in Gascony.
