AODH BUIDE Ó NÉILL

Aodh Buide (‘Hugh the Yellow’) Ó Néill — King of Tír Eóghain. After the O’Neills defeated the MacLoughlins at Caimeirge in 1241, his branch consolidated exclusive O’Neill control of Tyrone. His descendants later founded the O’Neills of Clandeboye.
1241

The MacLoughlins fell. The O’Neills ruled alone.

In 1167, the High King Ruaidrí Ó Conchobhair split the kingdom of Ailech in two: the portion north of Slieve Gallion to the Mac Lochlainn (MacLoughlin), and the portion south to the Ó Néill. The two dynasties fought for decades. At the Battle of Caimeirge in 1241, the O’Neills killed the MacLoughlin leadership and took sole control of Tír Eóghain. From 1241 onward, Tyrone was ruled exclusively by O’Neills.

Aodh Buide (“Hugh the Yellow”) was among the early O’Neill kings of this unified Tyrone. His descendants would later found the O’Neills of Clandeboye in eastern Ulster, a separate branch that expanded into the power vacuum left by the collapse of the Norman Earldom of Ulster in 1333.
