Dumnagual III: A King of Strathclyde

Dumnagual III ruled the ancient kingdom of Strathclyde. This kingdom was located in what is now parts of Scotland and England. Kings like Dumnagual were important leaders who protected their people and lands.

The Invasion of Strathclyde

A historical writer named Symeon of Durham tells us about a big event during Dumnagual's rule. Two powerful kings, King Óengus I of the Picts and King Eadberht of Northumbria, invaded Dumnagual's kingdom.

On August 1, 756, these kings reached Alt Clut, which is now known as Dumbarton Rock. This was Dumnagual's capital city. They managed to get the local people, called the Britons, to agree to their rule.

A Surprising Battle

But just nine days later, something surprising happened. King Eadberht's army from Northumbria was defeated while he was leading them. This happened somewhere between Govan and a place in Northumbria.

Historians usually think Dumnagual was the king of Alt Clut at this time. Some also suggest that King Óengus, not Dumnagual, was the one who defeated the Northumbrian army.

The End of His Reign

Records suggest Dumnagual died in battle around the year 760. After his death, it's believed that the land of Alt Clut was controlled by the Picts. It might have even been shared between the Picts and the English.

Dumnagual is the last king of Alt Clut from this time period that we know much about. For a while after him, we only know the names of the kings, not many details about their lives.
