Felim McHugh O'Connor (Irish: Feidhlimid mac Aedh Ó Conchobair, 1293–1316) was king of Connacht in Ireland from January 1310 to 10 August 1316.
He instead teamed up with some kinsmen who had been raiding against the Clan Murtagh O'Conor and his foster father Mac Diarmata killed Conchobar Ruad son of Aed Brefnech and carried great plunder back to O'Connor at Leyney.
Soon after they were forced to flee when Ruaidri lead an army against them and had his ally Diarmait Gall Mac Diarmata installed as king of Magh Luirg in opposition to Feidhlimid's foster father.
Looking for allies they submitted to the English of West Connacht and in the following year with their support they marched on Ruaidri and defeated him at the Battle of Tochar killing both him and Diarmait Gall, with Maelruanid Mac Diarmata being wounded in the fighting.
They meet at the Second Battle of Athenry where the Irish forces were defeated and O'Connor killed, being at the time only twenty three and described in the Annals of Connacht as ''entitled to become King of Ireland''.
Wiliam Burke followed up his victory by gaining submission of all the lords of Sil Muray, save Mac Diarmata who would be as active as ever in the kingship of Connacht until his death in 1322.
[8] The entry itself states: ''and he, Fedlimid mac Aeda meic Eogain, was proclaimed in a style as royal, as lordly and as public as any of his race from the time of Brian son of Eochu Muigmedoin till that day.
This can be seen as tying into the concept of sacral kingship for the early Irish period and the idea of the sovereignty goddess with the land as a woman whom, when the rightful King marries her, brings fertility and bounty.
