Bridei son of Beli
Bridei son of Beli, died 692 was king of Fortriu and of the Picts from 671 until 692. His reign marks the start of the period known to historians as the Verturian hegemony, a turning point in the history of Scotland, when the uniting of Pictish provinces under the over-kingship of the kings of Fortriu saw the development of a strong Pictish state and identity encompassing most of the peoples north of the Forth.
Bridei was probably brought up at the court of the Anglian kingdom of Northumbria, whose expansion had established it as the dominant power in northern Britain over the mid-7th century. His father was Beli, king of the British kingdom of Altclut, and his mother probably a daughter of Edwin of Northumbria, though his grandfather may have been the earlier Pictish king Nechtan nepos Uerb.
Bridei's rise to power in Fortriu probably took place under the patronage of his kinsman King Ecgfrith of Northumbria, after Bridei's predecessor Drest son of Donuel was expelled from the kingship after leading a rebellion against Northumbrian domination in 671. Bridei established an expansionary policy however, and in a series of campaigns between 679 and 683 built a confederation of Pictish territories owing allegiance to him through alliance and conquest. This brought him into conflict with Ecgfrith, who led an army north into Pictish territory in 685, culminating in the Battle of Dun Nechtain, when Ecgfrith was killed and the Northumbrian army destroyed by Bridei's forces.
Bridei's victory at Dun Nechtain marked the end of Northumbrian overlordship over the Picts, the Gaels and many of the Britons; and saw him consolidate his extensive territorial control. The following period saw the conscious development of the idea of the Picts as a single people under a single ruler; this process continued under the later kingships of Bridei son of Der-Ilei and Naiton son of Der-Ilei, who were probably his grandchildren.
Background
Political background
Before the Viking incursions that started in the late 8th century, the area of modern Scotland was divided between four main cultural and linguistic groupings: the Gaels of Dál Riata, the Britons, the Angles and the Picts, though identities and political groupings were in a constant state of flux and could often change among and between them. The Gaels occupied the west of modern Scotland north of the Firth of Clyde and were part of a Gaelic linguistic and cultural zone that included Ireland, from which it was separated only by the short sea crossing of the North Channel.To the south a number of British kingdoms had developed in the aftermath of the withdrawal of the Roman Empire, including Altclut in the basin of the River Clyde, Rheged to the south around the Solway Firth, and the Gododdin to the east around Edinburgh. In the south east Bernicia had been established as a Germanic-speaking Anglian kingdom based around Bamburgh in modern North East England in the mid 6th century, and by 638 had captured Edinburgh and gained much of the territory of the Goddodin around Lothian. The Picts largely occupied the lands in the east of modern Scotland north of the Forth and were originally a diverse group of peoples defined at least in part by never having been Romano-British.
The territory of the Picts was divided into two parts by the Mounth – the chain of high mountains that runs almost to the North Sea near Dunottar – and the northern and southern parts of the Pictish territory were further divided into smaller territories referred to by the Northumbrian writer Bede as prouinciae, at least some of which are recorded as kingdoms. Most significant of these was Fortriu, which was located north of the Mounth around the Moray Firth, encompassing the areas around Forres and Inverness, and whose primary centre of royal power probably lay at Burghead, which was three times larger than any other enclosed site in Early Medieval Scotland.
Between 653 and 685 the Picts were under Anglian overlordship through a series of puppet kings, as the expansionary kingdom of Northumbria came to dominate much of northern Britain. The southern Pictish lands south of the Mounth may have formed an Anglo-Pictish province controlled from Fife, whose ruling family may have included the Northumbrian noble Beornhæth. A document written in Rome between 678 and 681 records the claim of the Northumbrian bishop Wilfrid to primacy over "all the northern part of Britain and of Ireland and the Isles which are inhabited by the races of Angles, Britons, Gaels and Picts". In 681 the Northumbrian bishop Trumwine was appointed "Bishop of the Picts", though the location of his see at Abercorn, in Northumbrian territory south of the Forth, suggests that Northumbrian control of Pictish territory north of the Forth might still have been seen as insecure.
Family background
Bridei is described in a verse attributed to the broadly contemporary Adomnán as "son of the king of Dumbarton", indicating that he was the son of Beli, king of the British kingdom of Altclut; making Bridei also the grandson of Beli's predecessor Neithon son of Guipno; and the brother or half-brother of Beli's successor Eugein. The conflict between Bridei and Ecgfrith of Northumbria for Pictish supremacy is described in the poem Iniu feras Bruide cath as being over the legacy of Neithon, providing evidence that this Neithon son of Guipno, Bridei's grandfather, may have been the same person as the earlier Pictish king recorded as Nechtan grandson of Uerb, and that the Alt Clut dynasty into which Bridei was born may have had Pictish origins.Nennius' Historia Brittonum tells us that Bridei was King Ecgfrith's fratruelis or maternal first cousin, suggesting Bridei's mother was probably a daughter of King Edwin of Deira, and half-sister of the Northumbrian princess Eanflæd. The marriage of Bridei's parents would have marked an accommodation between Edwin and Neithon, extending Northumbrian influence into the lands of the Picts and of the Britons of the Clyde.
Life and reign
Early life
Bridei must have been born no later than 628, as the death of his father Beli of Alt Clut is recorded in the Annales Cambriae as taking place in 627. Bridei was probably brought up within the Northumbrian court, having possibly been taken there as a hostage by the Northumbrian king Oswiu after the killing of the Dal Riatan king Domnall Brecc by Bridei's half-brother Eugein of Alt Clut in 643.Rise to power
Accession of Bridei to the Pictish kingship seems to have been due at least in part to the influence of the Northumbrian kings Oswiu and Ecgfrith. Bridei was passed over several times for the succession to both the Pictish and Alt Clut kingships, probably as the fall of his grandfather Edwin of Northumbria in 633 diminished political connectedness of Bridei, but the marriage of his aunt Eanflæd to the newly crowned King of Bernicia Oswiu in 642 would have seen him once again become well-connected to the centres of Northumbrian power.Bridei became king after the expulsion in 671 of his predecessor Drest son of Donuel from his kingdom, which was probably centred around the northern Pictish district of Fortriu. This event is normally connected to the "Pictish rebellion" that culminated in the Battle of Two Rivers, suggesting Drest was leading an attempt to overthrow Northumbrian overlordship in the early years of the reign of Ecgfrith, after the death of Ecgfrith's powerful predecessor Oswiu. Stephen of Ripon records in his Life of St Wilfrid how the "bestial peoples of the Picts despised their subjection to the Saxons with a fierce disdain and threatened to throw off from themselves the yoke of servitude", before describing a Northumbrian victory so comprehensive it was "filling two rivers with corpses so that, amazing to say, the killers pursued the crowd of those fleeing, walking over the rivers dry foot". Stephen also records that Drest had "gathered together innumerable nations from every nook and corner in the north", suggesting that the Pictish forces were not otherwise politically united.
The expulsion of Drest and his replacement by Bridei was probably engineered by the combined power of Ecgfrith and Pictish supporters of Bridei. Bridei would have seen himself as a subject of Ecgfrith in 671 and may have been initially subject to an overlord from a southern Pictish territory such as Beornhaeth, a possibility supported by the description in the Annals of Inisfallen of the later Battle of Dun Nechtain between Bridei and Ecgfrith as "a great battle between Picts".
Expansion
Bridei seems have been actively intervening in the politics of Dál Riata in the early years of his reign. He may have been involved in the killing of Domangart mac Domnaill the king of Dál Riata in 673, and may also have entered into a three-way alliance with his nephew Dumnagual of Alt Clut and Finguine Fota of the Cenél Comgaill, king of Cowal and the grandfather of the later king of Fortriu Bridei son of Der-Ilei. The Annals of Ulster record that in 676 many Picts were drowned in Loch Awe, also suggesting an aggressive regime under Bridei attacking northern Dál Riata.In the 680s Bridei seems to have turned his attention away from Argyll, with a campaign that started less than a year after the Northumbrian king Ecgfrith was weakened by his defeat by Æthelred of Mercia at the Battle of the Trent in 679. A series of conflicts recorded in Irish annals as taking place in northern Britain from 679 are likely to represent Bridei expanding his power base. The Annals of Ulster describe a siege of Dunnottar in 680. Bridei attacked first Dunbeath in Caithness and then Orkney in 682, a campaign so violent that the Annals of Ulster said that the Orkney Islands were "destroyed" by Bridei. With opposition removed from the north, sieges of Dundurn in Strathearn and Dunadd in mid Argyll are reported the following year. As with the earlier siege of Dunnottar, Bridei, though not explicitly named, was probably the assailant.
Together Dunnottar and Dundurn mark the northern and southern limits of the southern Pictish territory south of the Mounth, and their sieges indicate a period of sustained pressure by Bridei across the area. The pattern of high-status sites attacked in Bridei's campaigns suggests they were the centres of independent provinces that resisted his rule, as he built a confederation of territories by alliance or conquest that owed allegiance and tribute to him as king. Bridei's model of over-kingship seems closely modelled on the system of tribute employed by the Picts' own Northumbrian over-lords.
