Godfrey of Bouillon
He warred on Henry's behalf against Magnus, Duke of Saxony, in 1075 and on that of the bishop of Utrecht in 1076 against Counts Dirk V of Holland and Robert I of Flanders. He was assassinated by spear in Vlaardingen while "answering the call of nature". Despite Matilda's opposition he nominated his nephew Godfrey of Bouillon to succeed him, but the emperor instead appointed his own son, Conrad. Godfrey of Bouillon succeeded eventually in 1087 and gained fame on the First Crusade.
