Summarize the Duke of Normandy from the 1220 period in 100 words.
I assume you are referring to King Henry III of Winchester (1207-1272), who apparently held the title Duke of Normandy from 1216-1259 when he renounced the title by treaty. Henry was the son of King John, who died in 1216. Henry was England's first child king since Ethelred the Unready two centuries before. Henry ruled for 56 years, but it was not a memorable reign; he fought with the English barons over "the Magna Carta and royal rights," and he was unsuccessful in his attempts to resecure the former English lands of Normandy and Aquitaine. He also called the first British parliament in 1264. However, the powerful English barons who had so hated King John found Henry more to their liking. Nevertheless, Henry's forces were defeated in 1263 by those led by Simon de Montfort at the Battle of Lewes during the Second Barons' War. Henry was placed under house arrest and served as a figurehead king for the next 15 months. However, Henry's son, Prince Edward, who had led the royalist army, escaped and rallied the army, defeating de Montfort's forces at the Battle of Evesham in 1265. Upon his death, Henry was succeeded by his son, who became King Edward I.
