Hugh O'Donnell
Hugh O'Donnell (Irish: Aodh mac Domhnaill Óic; died 1333) was king of Tyrconnell. He succeeded in 1281 after his father Donnell Óg O'Donnell was killed in battle against the O'Neills and the Ulster English.
In 1290 his brother Turlogh, backed by Scottish gallowglass, deposed him, but Hugh recovered the kingship the next year when an invasion by the Earl of Ulster overthrew Turlogh's regime. He ruled until 1333, dying in the monk's habit and buried at Assaroe Abbey. His son Connor succeeded him.
