Individual Details
(1110 - 1 May 1171)
In 1167, he was deprived of his kingdom by the High King of Ireland - Turlough Mór O'Connor. The grounds for the dispossession were that MacMurrough had, in 1152, abducted Derbforgaill, the wife of the King of Breifne, Tiernan O'Rourke. To recover his kingdom, MacMurrough solicited help from King Henry II of England. In return, MacMurrough pledged an oath of allegiance to Henry, who sent troops in support. As a further thanks for his reinstatement, MacMurrough's daughter Aoife was married to Richard de Clare, the 2nd Earl of Pembroke (nicknamed "Strongbow"). Henry II then mounted a larger second invasion in 1171 to ensure his control over Strongbow, resulting in the Lordship of Ireland. MacMurrough was later known as Diarmait na nGall (Irish for "Diarmait of the Foreigners").
