Flann may have had the intention of abandoning the traditional succession to the kingship of Tara, whereby the northern and southern branches of the Uí Néill held the kingship alternately, but such plans were thwarted when his favoured son Óengus was killed by his son-in-law and eventual successor
Niall Glúndub, son of Áed Findliath, on 7 February 915. Flann's other sons revolted and his authority collapsed.

in the early 7th century, had any king but an Uí Néill one been reckoned King of Tara in any account.
On Niall Caille's death in 846, the kingship of Tara passed to Flann Sinna's father Máel Sechnaill. Feidlimid died in the following year, and Máel Sechnaill proceeded to expand his power by war and diplomacy. What is noteworthy about Máel Sechnaill's expansionism, normal for Irish kings, is not that it happened, but the language used to describe it. The ''Annals of Ulster'' refer to Máel Sechnaill's armies, not as the "men of Mide", or of the Clann Cholmáin, but as the "men of Ireland" (an expedition ''co feraib Érenn'' is recorded in 858). Alongside this innovation, the terms ''goídil'' (
gael), ''gaill'' (foreigners) and ''gallgoídil'' (
Norse-Gaels) become more common, along with phrases such as the ''Gaíll Érenn'' (the foreigners of Ireland, used to refer to the Norse-Gaels of the Irish coasts).
On his death in 862, Máel Sechnaill's obituary titled him "King of all Ireland" ().
Áed Finnliath
On Máel Sechnaill's death, the Uí Néill kingship passed back to the northern branch, represented by
Áed Findliath, son of
Niall Caille. Áed began his reign by marrying Máel Sechnaill's widow, Flann's mother,

(d. 890), daughter of
Dúngal mac Cerbaill,
king of Osraige. Áed had some notable successes against the Vikings, and was active against the Laigin. However, his kingship was not accepted even among the southern Uí Néill. The historical records indicate that six times during his reign, or one year in three, the great Fair of

Tailtiu or Tailltiu (; modern spelling: Tailte) is the name of a presumed goddess from Irish mythology. The goddess's name is linked to Teltown (< OI ''Óenach Tailten'') in Co. Meath, site of the Óenach Tailten. A legendary dindsenchas "lore of ...
was not held, "although there was no just and worthy reason for this". When Áed died in 879, the kingship returned to the southern branch, represented by Flann Sinna.
During the reign of his stepfather, Flann enters the historical record. In 877, the ''Annals of Ulster'' record that "Donnchad son of Aedacán son of Conchobor, was deceitfully killed by Flann son of Máel Sechnaill". Donnchad, the reigning King of Mide and head of the southern Uí Néill, was Flann's second cousin. Flann's marriage to Áed Findliath's daughter Eithne may have taken place before he seized power, or soon afterwards.
Flann over Ireland
Flann's reign began with a demand for hostages from the kings of

. Unlike the later poetic accounts which made the Gaels and the "Foreigners" bitterest enemies, and recast events as a struggle between natives and incomers, Irish kings generally had no qualms about allying themselves with the "Foreigners" when convenient. It is likely that one of Flann's sisters was married to a Norse or Norse-Gael leader. Gerald of Wales offers a typically inventive account of how this marriage came about in his ''Topographia Hibernica''. Gerald claimed that Máel Sechnaill had granted his daughter to the Viking chieftain called ''Turgesius'', and he had sent fifteen beardless young men, disguised as the bride's handmaidens, to kill the chieftain and his closest associates.
The ''Annals of Ulster'' report that Flann was defeated in 887 by the "Foreigners" at the Battle of the Pilgrim. Among the dead on Flann's side were Áed mac Conchobair of the
Uí Briúin Ai,

In that year the Fair of Tailtiu was not held, a sign that Flann's authority was not unchallenged. Flann's defeat at the hands of the "Foreigners" was overshadowed by the signs of dissension among their leaders. That same year, the ''Annals of Ulster'' note that "Sigfrith son of Ímar, king of the Norsemen, was deceitfully killed by his kinsman". For the following year, the ''Annals'' report an "expedition by Domnall son of Áed

This was because Flaithbertach had fallen from his horse at the muster, an event which was taken to be an ill-omen. Flann and his allies subsequently defeated the Munstermen. Cormac, along with Cellach mac Cerbaill of Osraige and many other notables, was killed.
In 910, now without the aid of Cerball, who had died of sickness, Flann defeated the men of Bréifne. In 913 and 914, first Donnchad son of Flann, and then Flann himself, ravaged the lands of south Brega and southern Connaught. In the 914 campaign, the ''Annals of Ulster'' report that "many churches were profaned by

Niall Glúndub also compelled a truce between Flann and Fogartach mac Tolairg, king of Brega. Niall may also have been acknowledged as Flann's heir at this time. Flann did not long survive, dying near

Annals of Clonmacnoise'' have her wandering Ireland after Niall's death, forsaken by her kin, and reduced to begging from door to door, although this is thought to be a later invention rather than a tradition with a basis in fact.
The second of Flann's known marriages was his union with Eithne, daughter of Áed Findliath, dated

Eithne was also married to Flannácan, King of Brega, by whom she had a son named Máel Mithig, although whether this preceded her marriage to Flann is unclear. It is likely that Flann divorced Eithne in order to follow the tradition of marrying his predecessor's widow, Eithne's stepmother. Eithne died as a

The ''Annals of Ulster'' () are annals of History of Ireland, medieval Ireland. The entries span the years from 431 AD to 1540 AD. The entries up to 1489 AD were compiled in the late 15th century by the scribe Ruaidhrí Ó Luin� ...

'', kept at Clonmacnoise, Flann's own monastery, and perhaps compiled in his lifetime.
The description of Máel Ruanaid as "heir designate of Ireland" suggests to some that Flann planned to keep the kingship in his family, excluding the Cenél nEógain as the Cenél Conaill and Síl nÁedo Sláine had previously been excluded. The evident lack of filial loyalty among Flann's sons, Donnchad Donn being twice in rebellion against his father, may have prevented any such plans from coming to fruition. However, Óengus is called "heir designate of Temair
ara in the notice of his death in 915.
Benjamin Hudson suggested that it was only the vigorous campaigning by Niall Glúndub in Ulster and Connacht from 913 to 915, along with Óengus's fortuitous death, that led to Niall being named Flann's heir.
Alex Woolf suggested that Flann had not only attempted to monopolise the succession within his family, but had come close to instituting a national kingship in Ireland comparable to that created by his contemporaries

Later Clann Cholmáin kings were descended from Flann, as was
Congalach Cnogba, whose official pedigree pronounced him to be a member of the Síl nÁedo Sláine, the first of that branch of the Uí Néill to become King of Tara in two centuries, and whose last
agnatic ancestor to have ruled from Tara was the eponymous
Áed Sláine, ten generations before. Congalach was closely tied to Clann Cholmáin. His mother was Flann's daughter Lígach, and his paternal grandmother Eithne had been Flann's wife.

Flann was served by Máel Mura Othna (died 887), "chief poet of Ireland". In 885 Máel Mura composed the praise poem ''Flann for Érinn'' (Flann over Ireland). This linked Flann with the deeds of the legendary Uí Néill ancestor
Túathal Techtmar. As
Máire Herbert notes, Máel Mura depicts Tuathal as a 9th-century ruler, taking hostages from lesser kings, compelling their obedience and founding his kingship over Ireland on force. The high king in ''Flann for Érinn'' has authority over the ''fir Érenn'' (the men of Ireland) and leads them in war. This is very different from the way the kingship of Flann's 6th century ancestor
Diarmait mac Cerbaill is portrayed in early sources.
A concrete testimony to Flann's claims survives in the
