Máel Sechnaill
With Brian dead, Máel Sechnaill and Flaithbertach embarked on a series of campaigns which reestablished Máel Sechnaill as High King. According to the "Cogadh Gaedhel re Gallaibh", a work of propaganda composed in the time of Brian's great-grandson Muirchertach, in 1002, shortly before Brian replaced Máel Sechnaill as High King, Máel Sechnaill had offered to resign the High Kingship in favour of Áed mac Domnaill, Flaithbertach's uncle and predecessor as king of Ailech in return for aid against Brian. The "Cogadh" states that Áed refused and that no help came to Máel Sechnaill from Cenél nEógain and the north, only from Connacht. What caused Flaithbertach to support Máel Sechnaill where his uncle had not is unknown.
