at the Battle of Thurles, while the northern kings of Oriel and Northern Uí Néill repelled attacks on their kingdoms and raided and plundered much of northern Leinster. He signed the Treaty of Windsor with King Henry II of England. Whether he was unable or unwilling to, Henry did not or could not control the Norman barons, who continued conquering Irish territory, while Ruadhrí could not control the lesser Irish kings. This led to further conflict which would continue for centuries. Ruadhrí abdicated in 1183, but returned to rule briefly twice after that. Ruadhrí died in the year 1198. He would be the last Gaelic king of Ireland, except for perhaps Brian Ua Néill (died 1260). Children and descendants The last of Ruaidrí's descendants to hold the kingship of Connacht, Aedh mac Ruaidri Ua Conchobair, died in 1233. The Annals of Connacht give the following reason for this: Aed mac Ruaidri had been five years King of Connacht, as the poet said: 'Aed mac Ruaidri of the swift onslaught, five years his rule over the province, till he fell— a loss on every frontier— by the hand of Fedlimid.' Here ends the rule of the children of Ruaidri O Conchobair, King of Ireland. For the Pope offered him the title to [the kingship of] Ireland for himself and his seed for ever, and likewise six wives, if he would renounce the sin of adultery henceforth; and since he would not accept these terms God took the rule and sovranty from his seed for ever, in punishment for his sin. The annals and genealogies list thirteen children fathered by Ruaidrí. There may have been more. Conchobar Ua Conchobair Muirchertach Ua Conchobair Aedh Muimhnech Ua Conchobair. Had a son, Conchobar, alive in 1236. Domnall Mór Ua Conchobair. Had a son, Niall, killed 1242. Aed mac Ruaidrí Ua Conchobair, died 1159. The daughter of Ruaidhri Ua Conchobair, wife of [F]laithbertach Ua Maeldoraidh, was killed by the sons of Ua Cairella[i]n in 1176. Rose Ní Conchobair, married Hugh de Lacy, Lord of Meath about 1180, and had descendants. Conchobar Máenmaige Ua Conchobhair, died 1189. Diarmait mac Ruaidrí Ó Conchobair, died 1221.
