Irish chieftain

Niall Garve O'Donnell (Niall Garbh Ó Domhnaill; 1569 – 1626) was an Irish chieftain, alternately an ally of and rebel against English rule in Ireland. He is best known for siding with the English against his kinsman Hugh Roe O'Donnell during the Nine Years' War in the 1590s.

He was the son of Conn O'Donnell, the son of Calvagh O'Donnell the ruler of the lordship ("king") of Tyrconnell in Ulster. Among his brothers were Hugh Boy, Donal and Conn. Niall Garbh was incensed at the elevation of his cousin Hugh Roe (Red Hugh) to the chieftainship in 1592, was further alienated when the latter deprived him of his castle of Lifford, and a bitter feud between the two O'Donnells was the result. While Red Hugh O'Donnell was engaged in the Nine Years' War against the English, Niall Garve exploited the political situation to his own advantage. Niall Garve made terms with the English government, to whom he rendered valuable service both against the O'Neills and against his cousin, enabling an English force to land at Derry under Sir Henry Docwra: Docwra for a time regarded Niall as an invaluable ally. But in 1601 he quarrelled with the Lord Deputy of Ireland, who, though willing to establish Niall Garve in the lordship of Tyrconnell, would not permit him to enforce his supremacy over Sir Cahir O'Doherty in Inishowen. and also granted him the territorial Lordship of Tyrconnell. Niall Garve was later accused of turning against the Crown. When Sir Cahir O'Doherty launched an uprising by burning Derry in 1608, Niall Garve was charged with complicity in the ensuing O'Doherty's Rebellion. He and his son Neachtain were sent to the Tower of London, where they remained until their deaths.
