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.
After losing Osraige to the east, Cashel was established as the capital of Munster by the Eóganachta. This kindred ruled without interruption until the 10th century. Although the High Kingship of Ireland was dominated during this time by the Uí Néill, the Eóganachta of Munster did provide Cathal mac Finguine and Fedelmid mac Crimthainn as serious contenders. This great tribe was broken down into different septs or branches, the most successful in terms of royalty being the Eóganacht Chaisil (represented by the Ó Súilleabháin and Mac Cárthaigh), the Eóganacht Glendamnach (represented by the Ó Caoimh), and the Eóganacht Áine (represented by the Ó Ciarmhaic).
Their hold was loosened by the rise of Brian Bóruma of the Dál gCais, who established the Ó Briain as kings of Munster. As well as this, Munster had to contend with the Normans. Finally, the kingdom ended as it was split into Thomond, Desmond and Ormond. The former two came to an end during the 16th century with the birth of the Tudor Kingdom of Ireland, with former rulers joining the Peerage of Ireland. There were a number of Gaelic attempts to reassert their power in Munster, such as that of Fínghin Mac Cárthaigh and Domhnall Cam Ó Súilleabháin Bhéara, but these were not successful.
