Life

Sigtrygg was of
Norse and Irish ancestry.
He was a son of
Olaf Cuarán (also called Kváran),
King of York and of Dublin, and
Gormlaith ingen Murchada.
Gormlaith was the daughter of the
King of Leinster, Murchad mac Finn,
and the sister of his successor, King
Máel Mórda of Leinster.
She went on to marry the

Sigtrygg then attacked
Kells and
Clonard in 997.
In 998, Máel Sechnaill and the King of Munster, Brian Boru, forced Sigtrygg to recognise their lordship by giving
hostages.
Sigtrygg realised that Dublin's wealth made him a target, and that his city needed powerful allies and walls.
The
Dublin countryside did not provide sufficient resources for competition against powerful Irish princes.
Sigtrygg first allied with his maternal uncle,
Máel Mórda mac Murchada, King of the Uí Fáeláin of north Leinster.
In 999, they defeated their cousin, the King of Leinster,
Donnchad mac Domhnaill, and imprisoned him in Dublin.

This provided the opportunity for Sigtrygg's second alliance with

Battle of Glenmama, and followed the victory with an attack on the city of Dublin.
The 12th-century ''Cogadh Gaedhil re Gallaibh'' gives two accounts of the occupation: Brian remained in Dublin from

Archaeological excavations of ships, gold, clothing, and pieces for games from around this time seem to confirm the description.
According to the prose, Sigtrygg considered rewarding the poet with ships and gold, but instead granted him a new suit of clothes.
Second Leinster revolt against Brian Boru

Sometime during the 1010s, Brian Boru divorced Queen Gormflaith, and she began to engineer opposition to the High King. Around 1012, relations between Brian and Leinster had become so strained that revolt broke out among the Leinstermen.
Sigtrygg aligned himself with the forces of Máel Mórda, leader of the revolt, and the chiefs Ua Ruairc,

Sigtrygg sent his son Oleif to lead a fleet south to Munster to burn the Viking settlement of
Cork.
The fleet also attacked
Cape Clear, crippling Brian's naval power, which was concentrated in Cork.
According to ''Njál's saga'', Gormflaith "egged on her son Sigtrygg very much to kill King Brian",
sending him to win the support of
Earl Sigurd of Orkney, and
Bróðir and Óspak of Man at any price.

[Hudson, p. 103] ''Njal's Saga'' records that Sigtrygg was on the wing opposite Óspak of Man for the whole battle, and that Óspak eventually put the king to flight.
Reign after Clontarf
Immediately after Clontarf, Sigtrygg's fortunes appear to have declined, even though he emerged with his kingdom intact.
[Hudson, p. 104] Máel Sechnaill, now again recognised as high king, was undoubtedly the battle's main beneficiary.
In 1015, plague struck Dublin and Leinster, and Máel Sechnaill seized the opportunity to march south to burn Dublin's suburbs.
While Sigtrygg was able to ally with Leinster for another attack on Meath in 1017, the alliance was dissolved when Sigtrygg blinded his cousin Bróen, Máel Morda's son and heir, in Dublin.
In 1018, Sigtrygg plundered

In 1022, the Dublin fleet sailed north against the Ulaid, only to be destroyed in a naval battle against
Niall mac Eochaid, after which the Norse crews and ships were taken prisoner.
According to the American medievalist historian
Benjamin Hudson, "matters went from bad to worse" for Sigtrygg after the death of Máel Sechnaill in 1022.
[Hudson, p. 109] The great Irish princes began to compete for the High Kingship, and the political situation in Ireland became chaotic as there was no clear choice for supremacy.
Accordingly, "Dublin became a prize for those who would rule Ireland and wanted the town's wealth to finance their ambitions."

Hostages were taken from Sigtrygg by
Flaithbertach Ua Néill, King of Cenél nEógain and the Uí Néill, and
Donnchad mac Briain
Donnchadh mac Briain (old spelling: Donnchad mac Briain) (died 1064), son of Brian Boru, Brian Bóruma and Gormflaith ingen Murchada, was King of Munster.
Background
Brian Bóruma was the first man to establish himself as High King of Ireland by ...
of Munster in 1025 and 1026 respectively, in support of their bids for the high kingship.
These hostages brought no security, and Dublin was raided in 1026 by Niall mac Eocada of the Ulaid in revenge for the naval attack of 1022. Sigtrygg formed a new alliance with the men of

[Hudson, p. 111] The incident illustrates the importance of ransoming noble captives, as a means of political manipulation, increasing one's own revenues and exhausting the resources of one's foes.

In 1032, without allies, Sigtrygg won a victory on the
Boyne estuary of a type previously unseen by his dynasty for two decades, against a coalition of three kingdoms:
over 300 members of the
Conailli, the
Ui Tortain, and the
Ui Meith were captured or killed at the Battle of Inbher Boinne.
In 1035, he plundered the celebrated stone church of
Ardbraccan in Meath, burned 200 men inside, and carried another 200 off into captivity.
In revenge, the church at Swords was plundered and burned by Conchobhar Ua Maeleachlainn,
who took away cattle and captives.
Meanwhile, in a renewal of ancient feuds that same year, Sigtrygg executed Ragnall
King of Waterford, in Dublin.
Ragnall was the grandson of the Ivar, Sigtrygg's earliest rival, who had contested for Dublin decades before.

Separately from Sláine, Sigtrygg had five children: Artalach (d. 999), Oleif (d. 1013), Godfrey (d. 1036), Glúniairn (d. 1031) and Cellach (d. 1042).
The annals record the death of Oleif—"son of the lord of the foreigners"—who was killed in revenge for the burning of

Church Reform, to Sigtrygg.
[Richter, p. 125] He went on to found
Christ Church Cathedral in Dublin, which today is the oldest building in Dublin, but relatively young in comparison to the many monastic cathedrals in the rest of Ireland. Like many of the other coastal cathedrals in Ireland, it is of Hiberno-Norse origin. The cathedral, initially a wooden building, was rebuilt in stone in the 1180s following the
