King Felim
Felim, King of Munster, and for a time monarch of Ireland in the 9th century, is by some writers represented as having rivalled the worst deeds of the Danes in the devastation of his country, taking advantage of their incursions to plunder and lay waste the land. In one engagement he defeated the Ard-Righ Nial Caille, and carried off his daughter Gormlaith. O'Mahony says: "That he was nevertheless a brave and wise prince, within the limits of his own principality, may be judged from the fact that Munster was kept comparatively free from the ravages of the Northmen during his lifetime." O'Curry styles him "a distinguished scholar and a scribe." He died 18th August 845. His name is in Irish spelled Fedhlimidh.
