Louis VIII of France

Louis VIII (5 September 1187 – 8 November 1226), nicknamed The Lion (French: Le Lion), was King of France from 1223 to 1226. As a prince, he invaded England on 21 May 1216 and was excommunicated by a papal legate on 29 May 1216. On 2 June 1216, Louis was proclaimed "King of England" by rebellious barons in London, though never crowned. With the assistance of allies in England and Scotland he gained control of approximately one third of the English kingdom and part of Southern Wales. He was eventually defeated by English loyalists and those barons who swapped sides following the death of King John. After the Treaty of Lambeth, he was paid 10,000 marks, pledged never to invade England again, and was absolved of his excommunication. As prince and fulfilling the crusading vow of his father, Philip II, Louis led forces during the Albigensian Crusade in support of Simon de Montfort the Elder, from 1219 to 1223, and as king, from January 1226 to September 1226. Crowned king in 1223, Louis's ordinance against Jewish usury, a reversal of his father's policies, led to the establishment of Lombard moneylenders in Paris. Louis's campaigns in 1224 and 1226 against the Angevin Empire gained him Poitou, Saintonge, and La Rochelle as well as numerous cities in Languedoc, thus leaving the Angevin Kings of England with Gascony as their only remaining continental possession. Louis died in November 1226 from dysentery, while returning from the Albigensian Crusade, and was succeeded by his son, Louis IX.
