O'Brien, Turlough, King of Munster, nephew of preceding, was born about 1009, and upon the defeat of his uncle, Donough, assumed the sovereignty. In 1067 he and his allies marched against Connaught, but were caught in an ambush and defeated. Next year saw Turlough without a competitor, his cousin Murrough having been killed in a predatory excursion into Teffia. In 1073 he made preparations to reduce Ulster to obedience; but was defeated near Ardee. Better fortune awaited him in 1076, when he invaded Connaught and compelled the submission of Roderic O'Conor.

On the 29th October 1084, his son Murtough, with several allies, including the Danes of Dublin, fought an indecisive battle with the opposing Munstermen in Leinster. Four thousand were left dead on the field, including many princes of the O'Brien blood. In 1085 Turlough led a successful incursion into Ulster. He died at Kincora next year (1086), aged 76. He was twice married — to Gormlaith, a princess of Ely, and to Dervorghall, daughter of a prince of Ossory. Turlough O'Brien is said to have presented to William Rufus the oak with which the roof of Westminster Hall is constructed.
