thumb Simon de Montfort "the younger" or Simon VI de Montfort (April 1240 1271) was the second son of Simon de Montfort, 6th Earl of Leicester and Eleanor of England.
His father and his elder brother Henry were killed at the Battle of Evesham in August 1265: the younger Simon had been slow to bring his forces from London, and had seen them and their banners captured by Prince Edward, who then used the banners to trick the older Simon. The younger Simon tried to raise a rebellion in Lincolnshire, but this had petered out by Christmas.
He and his younger brother Guy escaped to France and Italy: in 1271 they discovered and murdered their cousin Henry of Almain at the church in Viterbo, for which they were excommunicated. Simon died later that year at Siena, "cursed by God, a wanderer and a fugitive".
