Maredudd ab Owain (died c. 999) was a 10th-century king in Wales of
the High Middle Ages. A member of the House of Dinefwr, his patrimony
was the kingdom of Deheubarth comprising the southern realms of Dyfed,
Ceredigion, and Brycheiniog. Upon the death of his father King Owain
around AD 988, he also inherited the kingdoms of Gwynedd and Powys,
which he had conquered for his father. He was counted among the Kings
of the Britons by the Chronicle of the Princes.
Maredudd was the younger son of King Owain of Deheubarth and the
grandson of King Hywel the Good. Owain had inherited the kingdom
through the early death of his brothers and Maredudd, too, came to the
throne through the death of his elder brother Einion around 984.
Around 986, Maredudd captured Gwynedd from its king Cadwallon ab
Ieuaf. He may have controlled all Wales apart from Gwent and
Maredudd is recorded as raiding Mercian settlements on the borders of
Radnor and as paying a ransom of a silver penny a head to rescue some
of his subjects who had been taken captive in Danish raids. Viking
raids were a constant problem during Maredudd's reign. In 987, Godfrey
Haroldson raided Anglesey, supposedly killing one thousand and
carrying away another two thousand as captives; Maredudd was said to
have then paid a huge ransom for the freedom of the hostages.
Following Maredudd's death around AD 999, the throne of Gwynedd was
recovered for the line of Idwal Foel by Cynan ap Hywel. The throne of
Deheubarth went to a man named Rhain who was accepted as Maredudd's
son by its people but who—after the kingdom's conquest by Llywelyn
ap Seisyll—was recorded by most Welsh histories as an Irish
pretender and usurper. The kingdom was later restored to Maredudd's
family, but through Hywel, the grandson of his brother Einion.
