Rhun ap Maelgwn

Rhun ap Maelgwn Gwynedd (died c. 586), also known as Rhun Hir ('Rhun the Tall'), sometimes spelt as "Rhûn", was King of Gwynedd from c. 547 to c. 586. He came to the throne on the death of his father, Maelgwn Gwynedd. There are no historical records of his reign at this early age. A story preserved in both the Venedotian Code and an elegy by Taliesin says that he waged a war against Rhydderch Hael of Alt Clut and the kings of Gododdin or Manaw Gododdin.

The small scattered settlement of Caerhun in the Conwy valley is said to be named for him, though without strong authority. Rhun also appears in several medieval literary stories, as well as in the Welsh Triads. His wife was Perwyr ferch Rhûn "Ryfeddfawr" and their son was Beli ap Rhun "Hîr". Rhun ap Maelgwn appears in the royal genealogies of the Harleian genealogies, Jesus College MS. 20, and Hengwrt MS. 202.

Bonedd y Saint ('The Descent of the Saints') says that he is the ancestor of Saint Edeyrn (Bonedd y Saint says that Edeyrn was the great-grandson of Rhun, while Hengwrt MS. 202 says that he was the grandson of Rhun).
