Reign

In 1106, with the support of his uncle Muirchertach Ua Briain, eighteen-year old Tairrdelbach deprived his older brother Domnall of the kingship of Connacht. He would remain king of Connacht for fifty years.

"Tairrdelbach carefully maintained his alliance with Ua Briain, sending troops to aid the high king agains the Ui Ruaric of Bréifne in 1109. But he was also determined to defend his kingdom against predators such as Domnall Mac Lochlainn (d. 1121), king of the north of Ireland." (O'Byrne, p. 471)

Tairrdelbach constructed Dún Bhun na Gaillimhe (“Fort at the Mouth (bottom) of the Gaillimh”) in 1124. A small settlement grew up around this fort and eventually this developed into Galway
