Urien Rheged

Urien ap Cynfarch Oer or Urien Rheged was a powerful sixth-century Brittonic-speaking figure who was possibly the ruler of the territory or kingdom known as Rheged. He is one of the best-known and best documented of the British figures of the Old North. His kingdom was most likely centred around the Solway Firth. According to the section known as the "Northern History" of the Historia Brittonum, Urien gained a decisive advantage in a conflict against the Anglo-Saxons in northern Britain while leading an alliance with three other kings: Rhydderch Hen, Gwallog ap Llênog, and Morgan. The alliance led by Urien penned the Anglo-Saxons in at Lindisfarne, though this siege came to an abrupt end when Urien was murdered on the orders of his erstwhile ally Morgan.
