Muiredach Tirech son of Fiacha Sraibhtine, was a legendary High King of Ireland of the fourth century. [1] He gained power by exiling the three Collas, who had killed his father. The Collas later returned and tried to provoke him into trying to kill them. When he did not, they entered his service and led his armies. He was overthrown by Cáelbad. [2] “In the beginning of the fourth century, Muiredeach Tireach, High King of Ireland, directed his nephews, the three Collas, to face north and win sword land for themselves. On the ruins of the old kingdom of Uladh they founded a new kingdom—of Airgíalla—which was henceforth for nearly a thousand years to play an important part in the history of Ireland, and which was possessed afterwards by their descendants, the MacMahons, O'Hanlons, O'Carrolls, and Maguires.” [3]
According to the Lebor Gabála Érenn [4] and its derivative works Muiredach Tírech was the father of Eochaid Mugmedón, High King of Ireland, and therefore grandfather of Niall of the Nine Hostages and ancestor of the Uí Néill and Connachta dynasties.
Conn Cétchathach, son of Fedlimid Rechtmar, was a legendary High King of Ireland and the ancestor of the Connachta, and, through his descendant Niall Noígiallach, the Uí Néill dynasties, which dominated Ireland in the early Middle Ages.
In Irish mythology, Fiacha, son of Delbáeth, of the Tuatha Dé Danann, was a legendary High King of Ireland. According to the Lebor Gabála Érenn, he took the throne after his father was overthrown by Caicher son of Nama, brother of Nechtan. The Annals of the Four Masters and Geoffrey Keating say he overthrew his father himself. His mother was Ernmas. He had three daughters, Banba, Fódla, and Ériu, by his own mother. He reigned for ten years, before he and his nephew Aoi Mac Ollamain were killed in battle against Éogan of Imber.
Lebor Gabála Érenn, known in English as The Book of Invasions, is a collection of poems and prose narratives in the Irish language intended to be a history of Ireland and the Irish from the creation of the world to the Middle Ages. There are a number of versions, the earliest of which was compiled by an anonymous writer in the 11th century. It synthesised narratives that had been developing over the foregoing centuries. The Lebor Gabála tells of Ireland being settled six times by six groups of people: the people of Cessair, the people of Partholón, the people of Nemed, the Fir Bolg, the Tuatha Dé Danann, and the Milesians. The first four groups are wiped out or forced to abandon the island; the fifth group represent Ireland's pagan gods, while the final group represent the Irish people.
The Mythological Cycle is a conventional grouping within Irish mythology. It consists of tales and poems about the god-like Tuatha Dé Danann, who are based on Ireland's pagan deities, and other mythical races such as the Fomorians and Fir Bolg. It is one of the four main story 'cycles' of early Irish myth and legend, along with the Ulster Cycle, the Fianna Cycle and the Cycles of the Kings. The name "Mythological Cycle" seems to have gained currency with Arbois de Jubainville c. 1881–1883. James MacKillop says the term is now "somewhat awkward", and John T. Koch notes it is "potentially misleading, in that the narratives in question represent only a small part of extant Irish mythology". He prefers T Ó Cathasaigh's name, Cycle of the Gods. Important works in the cycle are the Lebor Gabála Érenn, the Cath Maige Tuired, the Aided Chlainne Lir and Tochmarc Étaíne.

The Lebor Gabála Érenn says he ruled for either sixty or forty years before being killed by Art's son Bres Rí. The Lebor Gabála synchronises his reign with that of Cyaxares of the Medes. The chronology of Keating's Foras Feasa ar Éirinn dates his reign to 755–735 BC, that of the Annals of the Four Masters to 1002–962 BC. His son was Áedan Glas, whose son was Siomón Brecc mac Aedan.

His son Dui Ladrach later becomes High King. However, in Geoffrey Keating's Foras Feasa ar Éirinn and the Annals of the Four Masters he succeeds Art as High King and rules for seven or ten years, until he is killed by Ailill Finn, who succeeds him.

The Lebor Gabála Érenn synchronises his reign with that of the Roman emperor Nerva.

The Three Collas were, according to medieval Irish legend and historical tradition, the fourth-century sons of Eochaid Doimlén, son of Cairbre Lifechair. Their names were: Cairell Colla Uais; Muiredach Colla Fo Chrí ; and Áed Colla Menn. Colla Uais ruled as High King of Ireland for four years. Recent DNA analysis confirms the history of the Three Collas in fourth-century Ireland, but questions their descent from Eochaid Doimlén and Cairbre Lifechair.
