Richard de Clare, 2nd Earl of Pembroke, Lord of Leinster, Justiciar of Ireland, and Cambro-Norman lord notable for his leading role in the Norman invasion of Ireland, dies in Dublin on April 20, 1176. Like his father, he is also commonly known by his nickname “Strongbow.”
As the son of the 1st Earl of Pembroke, Richard succeeds to his father’s estates after his death in 1148, but is deprived of the title by King Henry II of England in 1154 for siding with King Stephen of England against Henry’s mother, the Empress Matilda. He sees an opportunity to reverse his bad fortune in 1168 when he meets Diarmait Mac Murchada, the deposed King of Leinster.
In 1167, Diarmait Mac Murchada is deprived of the Kingdom of Leinster by the High King of Ireland, Ruaidrí Ua Conchobair. To recover his kingdom, Mac Murchada solicits help from King Henry II of England. Henry provides a letter of comfort for willing supporters of Mac Murchada’s cause in his kingdom. However, after his return to Wales, he fails to rally any forces to his standard. He eventually meets Richard de Clare and other barons of the Welsh Marches. Mac Murchada comes to an agreement with de Clare where, for the Earl’s assistance with an army the following spring, he can have Mac Murchada’s eldest daughter, Aoife, in marriage and the succession to Leinster.
Mac Murchada and Richard de Clare raise a large army, which includes Welsh archers and arranges for Raymond FitzGerald to lead it. The force takes the Ostman towns of Wexford, Waterford, and Dublin in rapid succession between 1169 and 1170. Richard de Clare, however, is not with the first invading party and arrives later, in August 1170.
In May 1171, Diarmait Mac Murchada dies and his son, Donal MacMurrough-Kavanagh claims the kingdom of Leinster in accordance with his rights under the Brehon Laws. Richard de Clare also claims the kingship in the right of his wife. At this time, Strongbow sends his uncle, Hervey de Montmorency, on an embassy to Henry II, which is necessary to appease the King who is growing restive at the count’s increasing power. Upon his return, de Montmorency conveys the King’s terms – the return of Richard de Clare’s lands in France, England, and Wales as well as leaving him in possession of his Irish lands. In return, Richard de Clare surrenders Dublin, Waterford, and other fortresses to the English king. Henry’s intervention is successful and both the Gaelic and Norman lords in the south and east of Ireland accept his rule. Richard de Clare also agrees to assist Henry II in his upcoming war in France.
Richard de Clare dies on April 20, 1176 of an infection in his leg or foot. He is buried in Holy Trinity Church in Dublin with his uncle-in-law, Lorcán Ua Tuathail, Archbishop of Dublin, presiding. King Henry II takes all of Strongbow’s lands and castles for himself and places a royal official in charge of them.
