Gisulf I of Friuli
Gisulf I (Latin: Gisulfus I) was probably the first duke of Friuli (then Forum Julii). He was a nephew of Alboin, first king of the Lombards in Italy, who appointed him duke around 569 after the Lombard conquest of the region, though some scholars believe he appointed his brother Grasulf I, Gisulf's father.
Before this, Gisulf had been Alboin's marpahis or "master of the horse", sometimes considered a shield-bearer. He was, according to Paul the Deacon, "a man suitable in every way." He asked Alboin for permission to choose which faras or clans he would lead or rule over in Friuli, and this request was granted. He thus chose which families would settle permanently in Friuli, and he "acquired the honour of a leader (ducior)." As well, Alboin granted him a great herd of mares, perhaps in recognition of his former service.
