Where
Two blocs: the north around the Moy estuary in Sligo and Mayo, and the south in Galway near Kilmacduagh.
In today's counties: Sligo (Sligeach), Mayo (Maigh Eo).
When it mattered
Kings of Connacht on and off to the eighth century, then a regional power under the Ó Dubhda.
The Uí Fiachrach were a Connachta branch and for a time took their turn at the kingship of the province. From the eighth century the Uí Briúin got the better of them and the kingship settled elsewhere for good.
They remained a serious regional power all the same. The Ó Dubhda, the O'Dowds, ruled the country around the Moy, and the Book of Uí Fiachrach preserves their genealogies and the tribute lists of the territory in unusual detail.
What is left of the name
Tireragh in Sligo, Tír Fhiachrach, is the name still on the map.
