Cyngen Powys, King of Powys
Cyngen, son of King Cadell Powys, was the King who erected Eliseg's Pillar. He re-established Powysian independence after the Saxon invasions of 823, and probbaly transferred the Royal Court from Dinas-Bran to Mathrafal. Cyngen died on a pilgrimage to Rome in 854. His family, back in Powys, may have been quite young at the time, for his nephew, Rhodri Mawr (the Great) appears to have immediately imposed himself on the kingdom.
