diarmait mac murchada

diarmait mac murchada -lrb- modern irish : diarmaid mac murchadha -rrb- , anglicised as dermot macmurrough or dermod macmurrough -lrb- c. 1110c .
1 may 1171 -rrb- , was a king of leinster in ireland .
in 1167 , he was deprived of his kingdom by the high king of ireland -- ruaidri ua conchobair .
the grounds for the dispossession were that mac murchada had , in 1152 , abducted derbforgaill , the wife of the king of breifne , tiernan o'rourke -lrb- -rrb- .
to recover his kingdom , mac murchada solicited help from king henry ii of england .
in return , mac murchada pledged an oath of allegiance to henry , who sent troops in support .
as a further thanks for his reinstatement , mac murchada 's daughter aoife was married to richard de clare , the 2nd earl of pembroke -lrb- nicknamed `` strongbow '' -rrb- .
henry ii then mounted a larger second invasion in 1171 to ensure his control over strongbow , resulting in the lordship of ireland .
mac murchada was later known as diarmait na ngall -lrb- irish for `` diarmait of the foreigners '' -rrb- .
