About Aedh Ó Conchobair
Lived 1201 – 1301 (aged 99–100). Aedh Ó Conchobair was a monarch.
Hugh McOwen O'Conor (Irish: Aedh mac Eoghan Ó Conchobair) was king of Connacht in late medieval Ireland. He is the person addressed in the poem Cóir Connacht ar chath Laighean and in the poem An tu aris a raith Theamhrach by Aonghus Ruadh Ó Dálaigh.
Aedh Ó Conchobair was the son of Eoghan mac Ruaidri Ó Conchobair. In 1288 Magnus O'Conor, son of Conchobair Ruadh mac Muirchertaig Ó Conchobair, deposed his brother, Cathal O'Conor as king of Connacht. Upon the death of Magnus in 1293, Cathal briefly reclaimed the kingship, but some months later was killed. Aedh then became king.
In 1293 John FitzThomas FitzGerald, 4th Lord of Offaly built a castle at Sligo. The next year, it was levelled by O'Conchobair. In 1309 O' Conchobair was killed by Aedh Breifnech, of the Clan Murtagh O'Conor, who held the kingship for one year.
