Conchobar Maenmaige Ua Cellaigh, 40th King of Uí Maine and 7th Chief of the Name, died 1180.
Conchobar Maenmaige is agreed in all sources to have been king for forty years, so it appears he succeeded Tadhg Ua Cellaigh sometime after his abduction by an army from Munster in 1145.
His succession meant the end of Síol Anmchadha's brief independence and overlordship of Uí Maine, and its dynasty would henceforth be confined to their own homeland.
The Uí Maine appeared to take advantage of this, which cumulated in the Battle of the Conors, which took place at an unknown location, possibly within Máenmaige, sometime in 1180.
The victor was King Ruaidrí son, Conchobar Maenmaige Ua Conchobair, who had a palace at Dún Ló (Ballinasloe).
