notes or source: ancestry.com


The Battle of Mechain was fought in 1070 in Montgomeryshire, Wales, for rule of the Welsh kingdoms of Gwynedd and Powys.

After the murder of Gruffydd ap Llywelyn, Harold Godwinson married his widow Ealdgyth and divided Gruffydd's realm into the traditional kingdoms of Gwynedd and Powys, the rule of which were given to Bleddyn ap Cynfyn and his brother Rhiwallon ap Cynfyn. Gruffydd left two sons who in 1070 challenged Bleddyn and Rhiwallon at Mechain in an attempt to win back part of their father's kingdom. However, both of Gruffyd's sons were defeated, one being killed and the other dying of exposure after the battle.

Rhiwallon was also killed in this battle, leaving Bleddyn to rule Gwynedd and Powys alone.

Rhiwallon Ap Cynfyn became co-ruler of Gwynedd, Wales in 1063. He died in the Battle of Mechain.


A descendant of one branch of Rhodri The Great, he was a member of the House of Dinefwr. He ruled the Kingdoms of Gwynedd & Powys jointly with his brother, Bleddyn ap Cynfyn, as King of Deheubarth until his death in 1093 in the Battle of MeChain at the age of 45. His brother then ruled alone.


In August 1067, Rhiwallon and Bleddyn joined Eadric the Wild in an attack upon Herefordshire as part of the Saxon resistance to the recent Norman Conquest of England. In 1069 or 1070, the two brothers fought the battle of Battle of Mechain against Gruffydd's sons Maredudd and Idwal. Though victorious, Rhiwallon was slain in battle and left Bleddyn sole prince of North Wales.
