Conchobar was a son of Diarmait Ua Briain, King of Munster.[1] In 1138, Conchobar assumed the kingship of Munster.[2] The Annals of the Four Masters reveals that he gained the kingship of Dublin in 1141.[3] He died the following year.[4]
It is believed that Conchobar Ua Briain founded what is now known as Cahir Castle in the early 12th century. The fortress was a state-of-the-art defensive stronghold at the time, and continued to be in use for hundreds of years after being gifted to the Butler family in 1375 by Edward III.
