Óengus mac Mugróin

Óengus mac Mugróin (died 803) was a king of the Uí Failge, a Laigin people of County Offaly. He was the son of Mugrón mac Flainn (died 782), a previous king.^[1] He ruled from 783 to 803.^[2]

A conflict within the Uí Failge led to a slaughter in 789 at Cluain Ferta Mongáin (Kilclonfert, County Offaly) by Óengus at which his cousin Áed mac Tomaltaig was slain (their fathers were brothers).^[3] In 803 he was treacherously killed by the followers of Fínsnechta Cethardec mac Cellaig (died 808), over king of Leinster.^[4] Finsnechta was ensuring his control of the church of Kildare which led to conflict with the Uí Failge.

His grandson Máel Sinchill mac Mugróin (died 881) was a King of the Uí Failge.
