Cymraeg: Madog ap Maredudd, brenin of Powys English: Madog ap Maredudd, king of Powys[1]

Madog was the son of Maredudd ap Bleddyn ap Cynfyn.[1]

Madog married Susanna, chwaer (daughter of) Owain Gwynedd.[1]

Madog succeeded his father as King of Powys in 1132, [2] and was the last of his dynasty to rule as king over the whole of Powys.[1]

To combat the advances into his territory by Owain Gwynedd, king of Gwynedd, Madog allied firstly and unsuccessfully with Ranulf, earl of Chester, and later successfully with Henry II, king of England.[1]

Madog died in 1160 and he was buried in the mother church of Powys, St Tysillio at Melfod.[1] His dominions were divided among his sons and nephews: Gruffydd Maelor I, Owain Fychan, Owain Brogyntyn, and Owain Cyfeiliog.[1]

The leading poets of the day sang Madog's praises and he was enshrined in the prose romances of his day.[1]
