Sitric Cáech — the Ui Imair King of Dublin in the Early Tenth Century
Sitric Cáech, also known as Sihtric Cáech and Sigtrygg Gále, reigned as King of Dublin between 917 and 921. He restored the authority of the Vikings after his triumphant return to Dublin.
The campaigns waged by Sitric Cáech and his brothers, Ragnall and Godfraid, secured the dominance of the Hiberno-Scandinavian Ui Imair dynasty in Ireland during the Early Middle Ages.
Sitric Cáech — Return to Ireland in 917
The Annals of Ulster recounted Sitric Cáech and his fleet anchored at Cenn Fuait on the coast of Leinster in 917. He was the victor of the battle with Augaire mac Ailella, King of Leinster, and his Gaelic allies.
Scholars believe the most likely location of Cenn Fuait is Leixlip near the River Liffey in County Kildare. The Vikings founded a settlement at Leixlip in the ninth century. Leixlip, meaning “salmon leap” in Norse, was located near the border of Leinster and Brega.
The Chronicon Scotorum lamented the deaths of Augaire mac Ailella, King of Leinster, and fifty Gaelic kings at the Battle of Cenn Fuait. The demise of a multitude of Irish aristocrats on the battlefield left the provinces of Ireland without effective leadership.
Niall Glúndub, the High King of Ireland, was preoccupied with fighting Ragnall ua Imair and his Norse army in Munster. He rallied an army of the Northern and Southern Ui Neill and march south to Munster.
Ragnall ua Imair moored his Viking fleet near the longphort at Waterford in 917. He encountered Niall Glúndub and his army at the Battle of Mag Femen in County Tipperary. The confrontation proved indecisive.
Niall Glúndub besieged the camp of Ragnall ua Imair and the Vikings. He waited in vain for Augaire mac Ailella, King of Leinster, to arrive with reinforcements.
Sitric Cáech killed Augaire mac Ailella and annihilated his army at the Battle of Cenn Fuait. His victory over the Gaels paved the way for the successful invasion of Ireland by the Vikings.
Sitric Cáech attacked the monastery at Kildare to replenish supplies for his Norse army before marching to Dublin.
The Gaels in Leinster were defenceless against the devastation wreaked by Sitric Cáech and his Viking warriors.
The Annals of Ulster announced the return of the Sitric Cáech and the “Ostmen” to the royal stronghold of the Ui Imair dynasty in Dublin during 917.
Sitric Cáech and his brothers, Ragnall and Godfraid, regarded Dublin as their home. Their Scandinavian and Gaelic heritage forged the distinctive and illustrious Hiberno-Norse Ui Imair lineage of Dublin.
Sitric Cáech — Ui Imair King of Dublin
Sitric Cáech was the sole ruler of the Vikings in Dublin between 917 and 921. The Norwegian and Danish colonists accepted Sitric Cáech as their overlord in Ireland. His brothers, Ragnall and Godfraid ua Imair returned to Northern England with their ally, Ottir the Black, in 918.
Niall Glúndub, the High King of Ireland, and the Gaels witnessed the large-scale colonisation of the Vikings in the provinces of Ireland. They continued to resist Sitric Cáech and the Norse in Dublin despite suffering heavy casualties in previous conflicts.
The settlement of the Vikings along the rivers and coasts of Ireland induced the remaining Gaelic kings to ally with Niall Glúndub.
The Scandinavian invaders founded ports and settlements in the eastern parts of County Wicklow during the tenth century.
“Wicklow” means “grassy meadow by the creek” in Norse. The place-name suggested the dominance of the Vikings along the coast of Leinster.
Sitric Cáech sailed along the River Liffey to a settlement founded by the Danes at Leixlip in the ninth century. He killed Augaire mac Ailella, KIng of Leinster, at the Battle of Cenn Fuait in 917.
Leixlip, meaning “Salmon Leap” in Norse, was incorporated into the Viking kingdom of Dublin by Sitric Cáech.
The departure of Ragnall ua Imair and his brother, Godfraid, from Waterford in 918 seemed an opportune time to expel Sitric Cáech and the Norse colonists from Dublin.
The Chronicon Scotorum reported, Sitric Cáech and the Vikings of Dublin plundered Kildare for the second time in 918. Sitric Cáech demonstrated the military superiority of his professional Norse warriors by the ruthless devastation of the monasteries and settlements.
Niall Glúndub and an army of Irish clans fought Sitric Cáech and the Vikings of Dublin at the Battle of Islandbridge in 919.
Sitric Cáech annihilated the Gaelic forces during the conflict. Niall Glúndub died fighting bravely on the battlefield.
The Irish chroniclers lamented the deaths of Niall Glúndub and twelve Gaelic kings at the Battle of Islandbridge. Aed Mac Eochucan, King of Ulster and Mael Mithig mac Flannacán, King of Brega, were among the Irish aristocrats to perish at the hands of the Vikings.
Niall Glúndub was the most powerful Gaelic king in Ireland. He wielded great political influence as the leader of the Cenél nEógain or the Northern Ui Neill.
The death of Niall Glúndub was a watershed event in the history of Ireland. His demise allowed Sitric Cáech and the Hiberno-Scandinavian rulers of the Ui Imair dynasty to secure a permanent hold on Dublin for the next two hundred years.
Sitric Cáech assumed command of the Vikings in Ireland. He used his stronghold in Dublin to launch raids against the neighbouring Gaelic kingdoms in the Midlands. His fleets also plundered the monasteries and communities near the coasts of western Britain.
The Norse warriors stationed at Dublin subdued the Gaelic settlements in the surrounding countryside. They expelled local people from their raths or farmsteads and appropriated their land.
Sitric Cáech and Donnchadh Donn mac Flainn
Donnchadh Donn mac Flainn became King of Mide and the leader of the Clann Cholmáin, or Southern Ui Neill. He assumed authority after the death of his brother, Conchobar, at the Battle of Islandbridge in 919. The title of High King of Ireland also passed to Donnchadh Donn mac Flainn.
Donnchadh Donn mac Flainn and Muirchertach mac Néill of the Northern Ui Neill led the resistance against Sitric Cáech and Vikings of Dublin. Muirchertach mac Néill was known among his contemporaries as “Muirchertach of the Leather Cloaks”.
The Irish chroniclers celebrated the victory of Donnchadh Donn mac Flainn during fierce battles against the Vikings in County Louth in 920.
“Donnchad, grandson of Mael Sechnaill, inflicted a battle-rout on the heathens, in which a very large number were slaughtered.” (Annals of Ulster).
The Irish regarded the massacre of Vikings by Donnchadh Donn mac Flainn as retribution for the deaths of Niall Glúndub and their kings at the Battle of Islandbridge in 919.
Sitric Cáech looted and burned the monastery at Kells in County Meath in 920. Most of the monks “suffered violent death” during the attack.
He also burned down the nearby monastery of Dulane “on the same day”.
The Annals of Ulster reported in 920, “Sitriuc, grandson of Ímar, abandoned Áth Cliath, through the power of God”.
Sitric Cáech left Dublin for the City of York in Northumbria after his brother, Ragnall ua Imair, died in 921. York was the capital of the Viking colonists in the Danelaw of Northern England.
The Irish chroniclers recounted the arrival of Godfraid ua Imair in Dublin in 921. “Gothfrith grandson of Ímar entered Áth Cliath”.
Dublin became a centre of trade in Ireland and the Irish Sea region under the leadership of Sitric Cáech. The port occupied a central position between Britain, Scandinavia and Continental Europe.
Godfraid ua Imair reigned as King of Dublin after Sitric Cáech set sail for Northumbria in 921.
Conclusion
The Hiberno-Norse warlord, Sitric Cáech, dominated the political landscape of Ireland between 917 and 921. He successfully challenged the authority of Niall Glúndub, the High King of Ireland, to become a renowned figure among his contemporaries both at home and abroad.
The many achievements of Sitric Cáech included the restoration of Viking influence in Ireland and the rise of Dublin as a powerful Norse kingdom. His followers in Dublin enjoyed the wealth generated by the Scandinavian dominance of the slave trade in the Early Middle Ages.
Sitric Cáech and his brothers, Ragnall and Godfraid ua Imair, displayed the military genius of their grandfather, Ivar the Boneless. They restored the power of the Ui Imair kings of Viking Dublin for the next two hundred years.
