Dairmait Mac Murchada, King of Leinster and High King of Ireland

1110 - 1171  (61 years)

• Name	Dairmait Mac Murchada
  	Dairmait Mac Murchada was allied with Murtough MacLochlainn who was acknowledged as High King of Ireland in 1162. However, Murtough was overthrown in 1166 by Rory O'Connor and his Tiernan O'Rourke invaded Leinster, and Dairmait Mac Murchada fled to England in search of allies. King Henry II accepted Dairmait's allegiance, and gave him permission to recruit among his subjects for an expedition to Ireland. Dairmait struck a bargain with Richard FitzGilbert "Strongbow" deClare, 2nd Earl of Pembroke, who invaded Ireland, married Dairmait's daughter Aoife, and became King of Leinster when Dairmait died in 1171. King Henry II, fearful that Strongbow would set up an independent kingdom, came to Ireland to assert his authority over the lands that had been occupied. The King granted Leinster to Strongbow, Meath to Hugh de Lacy; and most of the Irish Kings quickly recognised Henry as their overlord. The Norse towns were of vital military and economic importance. King Henry annexed Dublin, Wexford, Waterford, Cork and Limerick; and left garrisons in all of them. Thus, Dairmait Mac Murchada is remembered for having brought the English to Ireland and is generally held in low esteem in Irish History. [2]
