Eochaid was a ninth-century Briton who may have ruled as King of Strathclyde and/or King of the Picts. He was a son of Rhun ab Arthgal, King of Strathclyde, and descended from a long line of British kings. Eochaid's mother is recorded to have been a daughter of Cináed mac Ailpín, King of the Picts. This maternal descent from the royal Alpínid dynasty may well account for the record of Eochaid reigning over the Pictish realm after the death of Cináed's son, Áed, in 878. According to various sources, Áed was slain by Giric, a man of uncertain ancestry, who is also accorded kingship after Áed's demise.
Echmarcach mac Ragnaill was a dominant figure in the eleventh-century Irish Sea region. At his height, he reigned as king over Dublin, the Isles, and perhaps the Rhinns of Galloway. The precise identity of Echmarcach's father, Ragnall, is uncertain. One possibility is that this man was one of two eleventh-century rulers of Waterford. Another possibility is that Echmarcach's father was an early eleventh-century ruler of the Isles. If any of these identifications are correct, Echmarcach may have been a member of the Uí Ímair kindred.
The Battle of Corbridge took place on the banks of the River Tyne near the village of Corbridge in Northumberland in the year 918.
Sitric Cáech or Sihtric Cáech or Sigtrygg Gále, was a Hiberno-Scandinavian Viking leader who ruled Dublin and then Viking Northumbria in the early 10th century. He was a grandson of Ímar and a member of the Uí Ímair. Sitric was most probably among those Vikings expelled from Dublin in 902, whereafter he may have ruled territory in the eastern Danelaw in England. In 917, he and his kinsman Ragnall ua Ímair sailed separate fleets to Ireland where they won several battles against local kings. Sitric successfully recaptured Dublin and established himself as king, while Ragnall returned to England to become King of Northumbria. In 919, Sitric won a victory at the Battle of Islandbridge over a coalition of local Irish kings who aimed to expel the Uí Ímair from Ireland. Six Irish kings were killed in the battle, including Niall Glúndub, overking of the Northern Uí Néill and High King of Ireland.
Arthgal ap Dyfnwal was a ninth-century king of Alt Clut. He descended from a long line of rulers of the British Kingdom of Alt Clut. Either he or his father, Dyfnwal ap Rhydderch, King of Alt Clut, may have reigned when the Britons are recorded to have burned the Pictish ecclesiastical site of Dunblane in 849.
Rhun ab Arthgal was a ninth-century King of Strathclyde. He is the only known son of Arthgal ap Dyfnwal, King of Alt Clut. In 870, during the latter's reign, the fortress of Alt Clut was captured by Vikings, after which Arthgal and his family may have been amongst the mass of prisoners taken back to Ireland. Two years later Arthgal is recorded to have been slain at the behest of Causantín mac Cináeda, King of the Picts. The circumstances surrounding this regicide are unknown. The fact that Rhun seems to have been Causantín's brother-in-law could account for Causantín's interference in the kingship of Alt Clut.
Flann mac Máel Sechnaill, better known as Flann Sinna, was the son of Máel Sechnaill mac Máele Ruanaid of Clann Cholmáin, the leading branch of the Southern Uí Néill. He was King of Mide from 877 onwards and a High King of Ireland. His mother Land ingen Dúngaile was a sister of Cerball mac Dúnlainge, King of Osraige.
Cerball mac Dúnlainge was king of Ossory in south-east Ireland. The kingdom of Ossory (Osraige) occupied roughly the area of modern County Kilkenny and western County Laois and lay between the larger provincial kingdoms of Munster and Leinster.
Amlaíb Conung was a Viking leader in Ireland and Scotland in the mid-late ninth century. He was the son of the king of Lochlann, identified in the non-contemporary Fragmentary Annals of Ireland as Gofraid, and brother of Auisle and Ímar, the latter of whom founded the Uí Ímair dynasty, and whose descendants would go on to dominate the Irish Sea region for several centuries. Another Viking leader, Halfdan Ragnarsson, is considered by some scholars to be another brother. The Irish Annals title Amlaíb, Ímar and Auisle "kings of the foreigners". Modern scholars use the title "kings of Dublin" after the Viking settlement which formed the base of their power. The epithet "Conung" is derived from the Old Norse konungr and simply means "king". Some scholars consider Amlaíb to be identical to Olaf the White, a Viking sea-king who features in the Landnámabók and other Icelandic sagas.
Ragnall mac Bárid ua Ímair or Rægnald was a Viking leader who ruled Northumbria and the Isle of Man in the early 10th century. He was a grandson of Ímar and a member of the Uí Ímair. Ragnall was most probably among those Vikings expelled from Dublin in 902, whereafter he may have ruled territory in southern Scotland or the Isle of Man. In 917, he and his kinsman Sitric Cáech sailed separate fleets to Ireland where they won several battles against local kings. Sitric successfully recaptured Dublin and established himself as king, while Ragnall returned to England. He fought against Constantín mac Áeda, King of Scotland, in the Battle of Corbridge in 918, and although the battle was not decisive it did allow Ragnall to establish himself as king at York.
Gofraid ua Ímair or Guthfrith of Ivar was a Hiberno-Scandinavian and Viking leader who ruled Dublin and briefly Viking Northumbria in the early 10th century. He was a grandson of Ímar and a member of the Uí Ímair. Gofraid was most probably among those Vikings expelled from Dublin in 902, whereafter he helped his kinsman Ragnall conquer Northumbria. Another kinsman, Sitric Cáech, became ruler of Dublin around the same time. Ragnall died in 920, and so the following year Sitric left Dublin to rule in Northumbria, and Gofraid succeeded Sitric as ruler of Dublin. Sitric's early reign was marked by raids he conducted against the Gaelic (Native-Irish), including one at Armagh.
Auisle or Óisle was a Viking leader in Ireland and Scotland in the mid-late ninth century. He was the son of the king of Lochlann, identified in the non-contemporary Fragmentary Annals of Ireland as Gofraid, and brother of Amlaíb Conung and Ímar, the latter of whom founded the Uí Ímair dynasty, and whose descendants would go on to dominate the Irish Sea region for several centuries. Another Viking leader, Halfdan Ragnarsson, is sometimes considered a brother. The Irish Annals title Auisle, Ímar and Amlaíb "kings of the foreigners". Modern scholars use the title "kings of Dublin" after the Viking settlement which formed the base of their power.
Maccus mac Arailt, or Maccus Haraldsson, was a tenth-century King of the Isles. Although his parentage is uncertain, surviving evidence suggests that he was the son of Harald Sigtryggson, also known as Aralt mac Sitriuc, the Hiberno-Norse King of Limerick. Maccus' family is known as the Meic Arailt kindred. He and his brother, Gofraid, are first recorded in the 970s. It was during this decade and the next that they conducted military operations against the Welsh of Anglesey, apparently taking advantage of dynastic strife within the Kingdom of Gwynedd.
Ímar, synonymous with Ivar the Boneless, was a powerful Viking leader in Ireland and Scotland in the mid-late ninth century. He was the progenitor of the Uí Ímair dynasty, who would go on to dominate the Irish Sea region for several centuries. He was the son of the king of Lochlann, identified in the non-contemporary Fragmentary Annals of Ireland as Gofraid. The Fragmentary Annals name Auisle and Amlaíb Conung as his brothers. Another Viking leader, Halfdan Ragnarsson, is considered by some scholars to be another brother. The Irish Annals title Amlaíb, Ímar and Auisle "kings of the foreigners". Modern scholars use the title "Kings of Dublin" after the Viking settlement which formed the base of their power. Some scholars consider Ímar to be identical to Ivar the Boneless, a Viking commander of the Great Heathen Army named in contemporary English sources who also appears in the Icelandic sagas as the eldest son of the legendary Viking Ragnar Lodbrok by third wife Aslaug.
Ragnall mac Gofraid was King of the Isles and likely a member of the Uí Ímair kindred. He was a son of Gofraid mac Arailt, King of the Isles. Ragnall and Gofraid flourished at a time when the Kingdom of the Isles seems to have suffered from Orcadian encroachment at the hands of Sigurðr Hlǫðvisson, Earl of Orkney. Gofraid died in 989. Although Ragnall is accorded the kingship upon his own death in 1004 or 1005, the succession after his father's death is uncertain.
Gofraid, King of Lochlann was a key figure in the emergence of Norse influence in Scotland and one of the early Kings of the Isles and of that dominated the Irish Sea and environs in the Early Middle Ages. Very little is known of him, including his origins and the nature of his kingdom, although his descendants are well attested in the Irish annals. Speculative connections between these historical figures and characters from the Norse sagas have also been made.
Ímar mac Arailt was an eleventh-century ruler of the Kingdom of Dublin and perhaps the Kingdom of the Isles. He was the son of a man named Aralt, and appears to have been a grandson of Amlaíb Cuarán, King of Northumbria and Dublin. Such a relationship would have meant that Ímar was a member of the Uí Ímair, and that he was a nephew of Amlaíb Cuarán's son, Sitriuc mac Amlaíb, King of Dublin, a man driven from Dublin by Echmarcach mac Ragnaill in 1036.
Bárid mac Ímar ; Old Norse: Bárðr or Bárǫðr ; d. 881) was a ninth-century King of Dublin. He was a son of Ivar (Ímar) Ragnarsson and a member of the Uí Ímair.
Ímar mac Bárid ; also known as Ivar II, was a Norse-Gaelic King of Dublin. He was a grandson of Ivar Gudrødsson and a member of the powerful Uí Ímair.
Tomrair was a ninth-century Viking active in Ireland. He is one of the first Vikings recorded by Irish sources. Tomrair is reported to have been killed at the Battle of Sciath Nechtain, a conflict in which twelve hundred Vikings were slain, battling the combined forces of Ólchobar mac Cináeda, King of Munster and Lorcán mac Cellaig, King of Leinster, in 848.
