Con of the Hundred Battles
Con the Hundred Fighter, commonly known as "Con of the Hundred Battles," was King of Ireland, 125 to 145. His reign was bloody and momentous. He early became involved in contentions with Mogh Nuadath concerning the throne of Munster. They ultimately divided the island between them, taking as boundary the Eskir Riada, or chain of gravelly hills running from Tallaght west to the Shannon at Clonmacnoise. Mogh retained the southern, and Con the northern part. Con is said to have procured the assassination of his rival. In the contests between them, Mogh drew many to his standard in times of scarcity by his large stores of provisions. Con was eventually assassinated within the precincts of Tara, by Tibradi Tirech, King of Ulster, and a band of fifty ruffians attired as women.
