1132 Accession as Prince of Powys
He succeeded his father in 1132 as Prince of Powys. 
He was the last of his dynasty to rule as king over the whole of Powys , including, for a time, the Fitzalan lordship of Oswestry (see Owain Brogyntyn ). 
Succeeding his father in 1132 , his main pre-occupation, particularly between the years 1149-57 , was the defence of Powys against the aggression of Owain Gwynedd (q.v.) . Threatened by the building of the castle of Tomen-y-Rhodwydd at the southern end of the Vale of Clwyd , Madog , in alliance with Ranulf , earl of Chester , unsuccessfully challenged Owain 's advance, losing, for a time, the control of his lands in Iâl . This loss was retrieved in 1157 when Henry II , with Madog 's support, made a decisive assertion of authority in North Wales . When he d. three years later he was still friendly with his powerful patron. 
To combat Owain Gwynedd's advances into Powis, Madog first allied with Ranulf, earl of Chester. It failed. His later alliance with Henry II was successful.
1148 Castle of Oswestry
The Chronicle of the Princes of Wales records that "Madog son of Maredudd built the castle of Oswestry" in 1148 and "gave Cyveiliog to his nephews Owain and Meurug, the sons of Gruffudd son of Maredudd". 
Marriage to Susann of Gwynedd
He married Susann of Gwynedd, daughter of Gruffydd ap Cynan King of Gwynedd & his wife Angharad of Deheubarth. 
While several sources identify Susanna as the daughter of Owain Gwynedd   Cawley in Foundation for Medieval Genealogy asserts that she was the daughter of Gruffydd ap Cynan (not ‘ Owain Gwynedd ’)
Madog is also shown in some genealogies as the husband of Efa (Eirian) ferch Madog. She apparently was a mistress of Madog, but not married to him. She has been delinked as a spouse but remains mother of shome of Madog's children.
