Madog ap Gruffydd Maelor , ruler in Powys (north)

Died: 1236   Active: 1191-1236   

Following the death of Madog's grandfather in 1160 the rulership of Powys was divided and Madog's father inherited the north; this came to be known as Powys Fadog. Madog succeeded his father in 1191. In 1211 Madog joined King John and many of the other Welsh rulers to oppose Llywelyn ab Iorwerth (d. 1240) but later he was a strong ally of Llywelyn.
