Harold (given name)
Harold is an English personal name. The modern name Harold ultimately derives from the Proto-Germanic *harja-waldaz, meaning 'military-power' or 'army-ruler'. The name entered Modern English via the Old English from Hereweald, which retained the same meaning and was prevalent in Anglo-Saxon England. The name's popularity in Viking Age England would also have been bolstered by the use of the Old Norse form Haraldr among Scandinavian settlers in the Danelaw.
