House of Rheged

[1] The dynasty includes Urien, King of Rheged and his son Sir Ywain a Knight of the Round Table in Arthurian legend.

His domain was partitioned between his children, leading to his great-grandson, Meirchion Gul, in the late 5th century, likely being the first of his descendants to exclusively rule Rheged.

They defeated the Angles and besieged them on Lindisfarne but, according to the Historia Brittonum, Urien was assassinated at the behest of Morgant Bwlch who was jealous of his power.

According to Bonedd Gwŷr y Gogledd Elidir's son, Llywarch Hen, was a ruler in North Britain in the 6th century.

Searching for Llywarch's kingdom has led some historians to propose that Rheged may have been divided between sons, resulting in northern and southern successor states.

The connections of the family of Llywarch and Urien with Powys has suggested to some, on grounds of proximity, that the area of modern Lancashire may have been their original home.
