Diarmait Mac Murchada (Modern Irish: Diarmaid Mac Murchadha), anglicised as Dermot MacMurrough, Dermod MacMurrough, or Dermot MacMorrogh (c. 1110 – c. 1 May 1171), was a King of Leinster in Ireland. In 1167, he was deposed by the High King of Ireland, Ruaidrí Ua Conchobair (Rory O'Connor). The grounds for the deposition were that Mac Murchada had, in 1152, abducted Derbforgaill, the wife of the king of Breifne, Tiernan O'Rourke (). To recover his kingdom, Mac Murchada solicited help from King Henry II of England. His issue unresolved, he gained the military support of the 2nd Earl of Pembroke (Richard de Clare, nicknamed "Strongbow"). At that time, Strongbow was in opposition to Henry II due to his support for Stephen, King of England against Henry's mother in the Anarchy. In exchange for his aid, Strongbow was promised in marriage to Mac Murchada's daughter Aoife with the right to succeed to the Kingship of Leinster. Henry II then mounted a larger second invasion in 1171 to ensure his control over Strongbow, resulting in the Norman Lordship of Ireland. Mac Murchada was later known as Diarmait na nGall (Irish for "Diarmait of the Foreigners"). He was seen in Irish history as the king that invited the first-ever wave of English settlers, who were planted by the Norman conquest. The invasion had a great deal of impact on Irish Christianity, increasing the de facto ability of the Holy See to regulate Christianity in Ireland. Early life and family Diarmait was born around 1110, a son of Donnchadh mac Murchada, King of Leinster and Dublin. His father's paternal grandmother, Derbforgaill, was a daughter of Donnchad, King of Munster and thus a granddaughter of Brian Boru. In 1115 his father attacked Domnall Gerrlámhach, King of Dublin, but died in the ensuing battle. The citizens of Dublin buried him with the carcass of a dog, considered to be a huge insult. He had two wives (as allowed under the Brehon laws), the first of whom, Sadhbh Ní Faeláin, was mother of a daughter named Órlaith who married Domnall Mór, King of Munster. His second wife, Mór ingen Muirchertaig, was mother of Aoife / Eva of Leinster and his youngest son Conchobar Mac Murchada. He also had two other sons, Domhnall Caomhánach mac Murchada and Énna Cennselach mac Murchada (blinded 1169). Diarmait is buried in the Cathedral graveyard of Ferns village.
