Fermanagh (Irish: Fir Manach) was a kingdom of Gaelic Ireland, associated geographically with present-day County Fermanagh. Fir Manach originally referred to a distinct kin group of alleged Laigin origins. The kingdom of Fermanagh was formed in the 10th century, out of the larger kingdom of Uí Chremthainn, which was part of the overkingdom of Airgíalla.[1] By the late 11th century it had grown to cover all of what is now County Fermanagh.[1] The kingdom came to be ruled by the Mag Uidhir (Maguire) clan from the late 13th century onward. They were based at Lisnaskea, and their royal inauguration site was nearby Sgiath Gabhra (Skeagoura), now called Cornashee.[2] Under Hugh Maguire, Fermanagh was involved in the Nine Years' War against English rule. His successor, Cú Chonnacht Óg Mag Uidhir, was one of the Gaelic Irish leaders who fled Ireland during the Flight of the Earls. Fermanagh was subsequently merged into the Kingdom of Ireland as County Fermanagh.
