King of Munster

The kings of Munster (Irish: Rí Mumhain) ruled the Kingdom of Munster in Ireland from its establishment during the Irish Iron Age until the High Middle Ages. According to Gaelic traditional history, laid out in works such as the Book of Invasions, the earliest king of Munster was Bodb Derg of the Tuatha Dé Danann. From the Gaelic peoples, an Érainn kindred known as the Dáirine (also known as Corcu Loígde and represented today in seniority by the Ó hEidirsceoil) provided several early monarchs including Cú Roí. In a process in the Cath Maige Mucrama, the Érainn lost their ascendancy in the 2nd century AD to the Deirgtine, ancestors of the Eóganachta. Munster during this period was classified as part of Leath Moga, or the southern-half, while other parts of Ireland were ruled mostly by the Connachta.
