The Uí Briúin were an Irish kin-group. Their eponymous apical ancestor was Brion, son of Eochaid Mugmedon and Mongfind, and an elder half brother of Niall of the Nine Hostages. They formed part of the Connachta, along with the Uí Fiachrach and Uí Ailello, putative descendants of Eochaid Mugmedon's sons Fiachra and Ailill. The Uí Ailello were later replaced as the third of the Three Connachta, by genealogical sleight of hand, by the Uí Maine.
Connacht was ruled in early times by the Uí Fiachrach, the Uí Briúin only becoming the dominant force in Connacht in 7th and 8th centuries.
The Uí Briúin divided into multiple septs, the major ones being:
Driftin' upward
Gently lifting
Lazy on the wind
Rollin' over
Turnin' slowly
Beginning and the end
Fire is bright
Fire is clean
Never so alive
Smoke is freedom
Flame is mercy
I am free tonight
And I burn
I burn
Stoke the embers
Cleanse the spirit
A prayer in every spark
Feel the lick of
Bad religion
The finish and the start
In the beginning
We were smarter
'n flame was heaven-sent
Through the ages
We got stupid
Now we must repent
And I burn
I burn
Save the ashes
For reminders
Stony things remain
Tooth and bone
unimpressive
I have left these things
Because fire is bright
Fire is clean
efficient and divine
Tooth and bone
Charms and dolls
I am free tonight
I BURN
THE AIR
YOU BREATHE
I BURN
THE AIR
YOU BREATHE
I BURN
THE AIR
YOU BREATHE
I burn
I burn
