Dumnagual III of Alt Clut
Encyclopedia
Dumnagual III was the ruler of Alt Clut
, later known as Strathclyde (the area around modern Dumbarton Rock), for some time in the mid-eighth century (probably 754–60). According to the Harleian genealogies
, he was the son of Teudebur
, one of his predecessors as king. According to Symeon of Durham
, his kingdom was invaded by both king Óengus mac Fergusa
of the Picts
and king Eadberht
of the Northumbrians. The same source indicates that on August 1, 756, they arrived at "Alcluth" and obtained the homage of the Britons
. However, nine days later, the Northumbrian king's army was destroyed, while Eadberht was leading it between Ouania and Niwanbirig, probably from Govan
back to Anglian Northumbria. Dumnagual is usually regarded as the king of Alt Clut in the period, but it has also been suggested that the likely destroyer of the Northumbrian army was Óengus. The Annales Cambriae
put Dumnagual's death at 760. It is thought likely that the territory of Alt Clut remained under Pictish or joint Pictish and English control in the years following his death. Dumnagual is the last British king of Alt Clut to be known as anything more than a name until the later ninth century.
