Brian Boru
Brian Boru (modern ;
c. 94123 April 1014), was an Irish king who ended the domination of the High Kingship of Ireland by the Uí Néill.
Bestowed the title of "Imperator Scottorum" or "Emperor of the Gaels" (commonly translated as "Emperor of the Irish"), he built on the achievements of his father, Cennétig mac Lorcain, and especially his elder brother, Mathgamain, Brian first made himself King of Munster, then subjugated Leinster, eventually becoming High King of Ireland.
He was the founder of the O'Brien dynasty, and is widely regarded as one of the most successful and unifying monarchs in medieval Ireland.
With a population of under 500,000 people, Ireland had over 150 kings, with greater or lesser domains.
The Uí Néill king Máel Sechnaill mac Domnaill, abandoned by his northern kinsmen of the Cenél nEógain and Cenél Conaill, acknowledged Brian as High King at Athlone in 1002.
In the decade that followed, Brian campaigned against the northern Uí Néill, who refused to accept his claims, against Leinster, where resistance was frequent, and against the Norse-Gaelic Kingdom of Dublin.
Brian's hard-won authority was seriously challenged in 1013 when his ally Máel Sechnaill was attacked by the Cenél nEógain king Flaithbertach Ua Néill, with the Ulstermen as his allies.
This was followed by further attacks on Máel Sechnaill by the Dubliners under their king Sihtric Silkbeard and the Leinstermen led by Máel Mórda mac Murchada.
Brian campaigned against these enemies in 1013.
In 1014, Brian's armies confronted the armies of Leinster and Dublin.
The resulting Battle of Clontarf saw Brian killed, his army nonetheless victorious against the Leinstermen and Norsemen.
The battle is widely lauded as an instrumental moment in Irish history, and is well known in popular memory.
Brian was well regarded by contemporary chroniclers.
The Norse-Gaels and Scandinavians also produced works mentioning Brian, including "Njal's Saga", the "Orkneyinga Saga", and the now-lost "Brian's Saga".
Brian's war against Máel Mórda and Sihtric was to be inextricably connected with his complicated marital relations, in particular his marriage to Gormlaith, Máel Mórda's sister and Sihtric's mother, who had been in turn the wife of Amlaíb Cuarán, king of Dublin and York, then of Máel Sechnaill, and finally of Brian.
Where Was I
" Where Was I?" may refer to:
Cacht ingen Ragnaill
Cacht ingen Ragnaill was the queen of Donnchad mac Briain, from their marriage in 1032 to her death in 1054, when she is styled Queen of Ireland in the Irish annals of the Clonmacnoise group: the Annals of Tigernach and Chronicon Scotorum.
Her husband himself, though King of Munster, is not widely regarded as having been High King of Ireland and so the extent of Cacht's influence is uncertain.
That her style is superior to his presents an obviously strange situation in medieval Gaelic Ireland's male- dominated politics.
Of Norse- Irish descent, Cacht almost certainly belonged to the dynasty of the Uí Ímair, and is usually assumed to have been a sister of Donnchad's ally Echmarcach mac Ragnaill, whose precise parentage is uncertain.
He is regarded by scholars either as a descendant of Ivar of Waterford, or of Gofraid mac Arailt, but since both had children named Ragnall and both dynasties were in alliance with the Dál Cais, Cacht's father need not be identical with his.
Domhnall mac Briain
Domhnall Mac Briain was the son of Brian Boru, the High king of Ireland and Eacraidh whose father was a Rí of a tuath in Mide.
He had two known siblings, one brother( Tadc) and a sister.
The Annals of Inisfallen record that he raided Cenél Conaill.
Half of the army was led by Domhnall, while the other half by his half brother Murchad mac Briain.
He died in 1012 due to natural causes.
He had no children.
Toirdelbach Ua Briain
Toirdhealbhach Ua Briain( old spelling: Toirdelbach Ua Briain), anglicised" Turlough O'Brien"( 100914 July 1086), was King of Munster and effectively High King of Ireland.
A grandson of Brian Bóruma, Toirdelbach was the son of Tadc mac Briain who was killed in 1023 by his half- brother Donnchad mac Briain.
For the first forty years of his life nothing is known of Toirdelbach.
It was not until the 1050s that he found allies in Connacht and in Leinster, particularly the powerful King of Leinster Diarmait mac Maíl na mB ó, who would aid his claims to be ruler of Munster.
It took perhaps ten years of sustained attack to remove his uncle Donnchad from power, and send him into exile, and to place Toirdelbach in power in Munster as Diarmait's faithful ally.
On Diarmait's death Toirdelbach took over the reins of power, establishing himself as ruler of more than half of Ireland.
While not a great military leader, he was a capable politician whose influence extended as far north as Ulaid and who made and unmade Kings of Connacht.
He died after more than two decades in power, following a lengthy illness, still in control of events.
His son Muirchertach Ua Briain would be the leading king of his day, and his grandson Toirdelbach Ua Conchobair would be greater yet.
