Madog was the son of Maredudd ap Bleddyn and grandson of Bleddyn ap Cynfyn. He followed his father on the throne of Powys in 1132. He is recorded as taking part in the Battle of Lincoln in 1141 in support of the Earl of Chester, along with Owain Gwynedd's brother Cadwaladr ap Gruffydd and a large army of Welshmen. In 1149 he is recorded giving the commote of Cyfeiliog to his nephews Owain Cyfeiliog and Meurig. The same year Madog was able to rebuild Oswestry Castle, a fortress of William Fitzalan. It would seem likely that he had gained both the fortresses of Oswestry and Whittington in 1146.

Defeat by Gwynedd

At this time the King of Gwynedd, between 1149 and 1150, Owain Gwynedd was exerting pressure on the borders of Powys, despite the fact that Madog was married to Susanna, Owain's sister. Madog made an alliance with Ranulf de Gernon, 4th Earl of Chester, but Owain defeated them at the Battle of Ewloe (Coleshill) in 1150 and took possession of Madog's lands in Iâl (English: Yale). In 1157 when King Henry II of England invaded Gwynedd he was supported by Madog, who was able to regain many of his Welsh lands. Even so, he retained the lordships of Oswestry and Whittington. In 1159 Madog would seem to have been the Welsh prince who accompanied King Henry II in his campaign to Toulouse which ended in failure. Returning home to Wales Madog died about 9 February 1160 in Whittington Castle. He was buried soon afterwards in the church of St Tysilio at Meifod, the mother church of Powys.

Succession Shared

Madog's eldest son, Llywelyn, was killed soon after his father's death in 1160, Powys was then shared between Madog's sons Gruffydd Maelor, Owain Fychan and Owain Brogyntyn, his nephew Owain Cyfeiliog and half-brother Iorwerth Goch. [1] Powys was never subsequently reunited, being separated into two parts; Powys Fadog (Lower Powys) and Powys Wenwynwyn (Upper Powys). Madog's death enabled Owain Gwynedd to force the homage of Owain Brogyntyn, Madog's youngest son, and effectively annex part of northern Powys.

The poet Cynddelw Brydydd Mawr in his elegy on Madog said:

While Madog lived there was no man
Dared ravage his fair borders
Yet nought of all he held
Esteemed he his save by God's might ...
If my noble lord were alive
Gwynedd would not now be encamped in the heart of Edeyrnion

Edeyrnion (or Edeirnion) was a commote inherited by Owain Brogyntyn and had been the home of his mother (who was not married to his father). Owain may also have been raised there. It was annexed to Gwynedd during Owain's time.

The Mabinogion

The Mabinogion tale The Dream of Rhonabwy is set during Madog's reign. The central character, Rhonabwy, is one of Madog's retainers sent to bring in Madog's rebellious brother Iowerth Goch ap Maredudd. His titular dream contrasts his own time with the grandeur of King Arthur's period. [2]



Madog's intervention in the Battle of Lincoln in 1141 forms an important plot element in the detective novel Dead Man's Ransom, part of the Brother Cadfael chronicles by Edith Pargeter (writing as Ellis Peters).

Kingdom of Powys Medieval kingdom in Wales

The Kingdom of Powys was a Welsh successor state, petty kingdom and principality that emerged during the Middle Ages following the end of Roman rule in Britain. It very roughly covered the northern two-thirds of the modern county of Powys and part of today's English West Midlands. More precisely, and based on the Romano-British tribal lands of the Ordovices in the west and the Cornovii in the east, its boundaries originally extended from the Cambrian Mountains in the west to include the modern West Midlands region of England in the east. The fertile river valleys of the Severn and Tern are found here, and this region is referred to in later Welsh literature as "the Paradise of Powys".

Bleddyn ap Cynfyn, sometimes spelled Blethyn, was an 11th-century Welsh king.

He became king of Powys and co-ruler of the Kingdom of Powys with his brother Rhiwallon from 1063 to 1075. His descendants continued to rule Powys as the House of Mathrafal.

Owain Brogyntyn

Owain Brogyntyn ap Madog was the third and illegitimate son of king Madog ap Maredudd, the last king of a united Kingdom of Powys. He was the son of Madog by the daughter of the Maer du or "black mayor" of Rûg in Edeyrnion however some sources cite his mother as Susanna making him legitimate instead. He was the brother of Gruffydd Maelor the ancestor of Owain Glyndŵr. Presumably Owain Brogyntyn would have been raised by his mother at Rûg in Edeyrnion. He was acknowledged by his father and granted by him the lordship of Edeyrnion and also Dinmael. It is quite possible that he inherited some of these lands through his maternal grandfather, the Maer Du, which were confirmed and perhaps extended by his father the king of Powys. At some point he also came into possession of Castle Brogyntyn on the English borders at Selattyn close to Oswestry.
