The Dáirine (named for Dáire mac Dedad), or Clanna Dedad, a major branch of the Érainn, were a significant power in Gaelic Ireland, providing several High Kings of Ireland at the Hill of Tara in addition to ruling Munster. There was also a Temair Luachra (Tara of the Rushes), existing as the royal site of Munster, but this is lost to history (it is potentially synonymous with Caherconree). Some of the most prominent High Kings from this time provided by the Érainn of Munster include Eterscél Mór and Conaire Mór who are the subject of the Togail Bruidne Dá Derga. The Laigin in particular were major rivals for Munster at the time. The Chronicle of Ireland places the start of these rulers at roughly the 1st century BCE. Outside of Gaelic sources, the predominant people of Munster, the Érainn, along with other tribes in the area are attested to in Ptolemy's Geographia, where they are known as the Iverni.
