Madog son of Maredudd (Madog ap Maredudd) was ruler of the Welsh kingdom of Powys between 1132 and his death in 1160. He was the last Welsh ruler to have the whole of Powys under his control. The geographical position of Powys meant that it was vulnerable to attack from the powerful kingdom of Gwynedd and from England. It is probably for this reason that Madog made sure he kept on good terms with the English King and members of the English nobility.
