O'Donnell Dynasty - Territory

Territory

Tyrconnell, the territory named after the Cenel Conaill, is the vast territory where the O'Donnells held sway, comprised the greater part of the modern county of Donegal except the peninsula of Inishowen. But it also included areas outside Donegal, such as the baronies of Carbury in County Sligo, Rosclogher in County Leitrim, and Magheraboy and Firlurg in County Fermanagh, and part of southern County Londonderry, hence it straddled the modern Republic of Ireland and also part of Northern Ireland in the UK. The jewel in the O'Donnell crown was Donegal Castle, one of seven O'Donnell castles, and now a national monument partially restored by the Office of Public Works. Tyrconnell also therefore bordered on territory ruled by the O'Neills of Tyrone, who were periodically attempting to assert their claim of supremacy over it, and hence the history of the O'Donnells is for the most part a record of clan warfare with their powerful neighbours, and of their own efforts to make good their claims to the overlordship of northern Connacht, and a wider swathe of Ulster. Nonetheless Tyrconnell existed for a period as an independent kingdom, recognised by King Henry III of England (see Close Roll, in the Tower of London, 28 Hen. 3m.7).
