The Duchy of Aquitaine came into personal union with the Kingdom of England upon the accession of Henry II, who had married Eleanor, Duchess of Aquitaine. The Kingdom of England and the Duchy of Normandy remained in personal union until John Lackland, Henry II's son and fifth-generation descendant of William I, lost the continental possessions of the Duchy to Philip II of France in 1204. A few remnants of Normandy, including the Channel Islands, remained in John's possession, together with most of the Duchy of Aquitaine.
