The kingdom of Powys covered the eastern part of central Wales. Regions included Builth and Gwerthrynion. It is important to note it was occupied by the Irish for a few years by Banadl (usually given as 441-447 AD), and was united with Gwynedd in 854 upon the death of Cyngen ap Cadell by his nephew Rhodri.
