Manwgan, King of Powys
Manwgan appears to have been a very small boy when his father, Selyf Sarffgadau (Battle-Snake) was killed at the Battle of Caer-Legion (Chester) in 613. One theory asserts that this led to an invasion of Powys by Eluadd ap Glast (alias Eluan Powys), the erstwhile King of Dogfeiling. The usurper probably managed to hold the throne for some thirty years or more before he was killed fighting the Northumbrians, possibly at the Battle of Maes-Cogwy (Oswestry) in 642. The Dogfeiling dynasty was finally crushed by the Saxons around 656, and Manwgan was able to take his rightful place on the Powysian throne.
