List of rulers of the Kingdom of the Isles
The Kingdom of the Isles comprised the Hebrides, the islands of the Firth of Clyde and the Isle of Man from the 9th to the 13th centuries AD. The islands were known to the Norse as the Suðreyjar, or "Southern Isles" as distinct from the Norðreyjar or Northern Isles of Orkney and Shetland. The historical record is incomplete and the kingdom was probably not a continuous entity throughout the entire period. The islands concerned are sometimes referred to as the "Kingdom of Mann and the Isles", although only some of the later rulers claimed that title.[Note 1] At times the rulers were independent of external control, although for much of the period they had overlords in Norway, Ireland, England, Scotland or Orkney. At times there also appear to have been competing claims for all or parts of the territory. The islands involved have a total land area of over 8,300 square kilometres (3,205 sq mi)[Note 2] and extend for more than 500 kilometres (310 mi) from north to south.
Viking influence in the area commenced in the late 8th century, and whilst there is no doubt that the Uí Ímair dynasty played a prominent role in this early period, the records for the dates and details of the rulers are speculative until the mid-10th century. Hostility between the Kings of the Isles and the rulers of Ireland, and intervention by the crown of Norway (either directly or through their vassals the Earls of Orkney) were recurring themes.
Invasion by Magnus Barelegs in the late 11th century resulted in a brief period of direct Norwegian rule over the kingdom, but soon the descendants of Godred Crovan re-asserted a further period of largely independent overlordship. This came to an end with the emergence of Somerled, on whose death in 1164 the kingdom was split in two. Just over a century later the islands became part of the Kingdom of Scotland, following the 1266 Treaty of Perth.
The orthography of the rulers' names is complicated as Old Norse and Gaelic were both spoken throughout the region for much of period under consideration. Thus a single individual might be referred to as Rognvaldr in Icelandic sources, Rag(h)nall in Gaelic, Reginaldus in Latin and perhaps "Rognvald" or "Reginald" in English language sources.[Note 3]
9th and early 10th centuries
During this period the historical record is particularly sparse and these early entries must be considered as somewhat speculative.
|Ruler of the Hebrides||Dates||Title||Notes|
|Unknown father of Thórir||848||King of Viking Scotland||According to the Orkneyinga saga Rognvald Eysteinsson had a number of sons including Ivar and Thorir the Silent, Ivar being killed in battle during Harald Fairhair's expedition to the west. According to Irish sources Thorir was the heir of a king of "Viking Scotland" who took an army to Ireland in 848.|
|Gofraid mac Fergusa||d. 853||Lord of the Hebrides||The Annals of the Four Masters calls him toisech Innsi Gall.[Note 4]|
|Gofraidh||pre 872–873||King of Lochlann||Father of Amlaíb Conung and Ímar|
|Ímar||873||King of the Norwegian Vikings of the whole of Ireland and Britain||May have succeeded his father briefly|
|Amlaíb Conung||873||King of the Northmen/King of the Western Sea[Note 5]||Ímar's brother|
|Ketill Flatnose||c 890–900||King of the Isles||The earliest certain written references to Ketill are from the sagas written 200 years or more after his death. Unlikely to have been ruler of Mann and may have ruled in the mid, rather than late ninth century.[Note 6]|
|Unknown||c 900–941||Possibly ruled by Uí Ímair dynasts Ragnall ua Ímair (d. 920/1) who ruled Mann, Sitric Cáech (d. 927), Gofraid ua Ímair (d. 934) and Amlaíb mac Gofraid (d. 941) as Kings of Dublin.[Note 7]|
It is also possible that Eiríkr, King of York from 947–948 and 952–5, was a ruler in the islands at some stage in the mid-10th century. Eiríkr is believed by some authorities to be synonymous with the saga character Eric Bloodaxe, although the connection is questioned by Downham (2007), who argues that the former was an Uí Ímair dynast rather than a son of Harald Fairhair. A raid on Northumbria in 949, the purpose of which may have been either to support or oppose the kingship of Amlaíb Cuarán is described as predam albidosorum idem nannindisi in the Chronicle of the Kings of Alba. Alfred P. Smyth translated this as "the raid of the men from beyond the spine of Britain, that is, of the islands."

Early rulers of Mann
Various rulers have been identified as ruling Man, but not the Isles as a whole. The Isle of Man may have fallen under Norse rule in the 870s, and paradoxically they may have brought the Gaelic language with them. The island has produced a more densely distributed Viking Age archaeology than anywhere else in the British Isles, but the written records for this time period are poor.
|Rulers of Mann||Period of Reign||Title(s)||Notes|
|Otir||912?–914?||Jarl and "Master of the Isle of Man"||Possibly as a vassal of Ragnall ua Ímair|
|Ragnall ua Ímair||914 to 921?||?||Defeated Bárid son of Otir in a naval battle off Man in 914|
|Gothfrith ua Ímair[Note 12]||pre 927 to?||Father of Amlaíb|
|Amlaíb mac Gofraid[Note 13]||pre 935 to 941||King of Northumbria and possibly King of the Isles[Note 14]||After the death of Athelstan in 939, Edmund ceded Northumbria to Amlaíb. Married a daughter of Constantine II.|
There then follows a period when it is likely that the Western Isles and Mann were jointly held by rulers of the House of Ímar (see above). Downham (2007) suggests Lagmann Godredson may have "wielded power in Man" and possibly even have been king but was expelled sometime after 1005, perhaps by Brian Bóruma. This may indicate that the Earls of Orkney did not control Man itself in the early 11th century. Echmarcach mac Ragnaill and his successors certainly did control Mann, but the extent of their rule over the islands of the Clyde and the Hebrides is not clear. Óláfr mac Lagmann (or Lagmainn) is recorded as having been killed at Clontarf in 1014, fighting with "warriors from the Hebrides".
|Rulers of Mann||Period of Rule||Title||Notes|
|Lagmann mac Gofraid||?–1005||"King of the Swedes"||Possibly a son of Gofraid mac Arailt[Note 15]|
|Ottar||d. 1098||Jarl||Earl of "one half of Man"|
The period 1095–1098 seems to have been politically unsettled, culminating in a Manx civil war between the north and south of the island. A battle at Santwat between the northerners under Jarl Óttar and the southerners under Macmaras (or MacManus) in 1098 resulted in the deaths of both leaders.
Early rulers of the Hebrides
In Irish mythology the Outer Hebrides were the home of the Fomorians, described as "huge and ugly" and "ship men of the sea". They were pirates, extracting tribute from the coasts of Ireland and one of their kings was Indech mac Dé Domnand (i.e. Indech, son of the goddess Domnu, who ruled over the deep seas). Indech is also mentioned in the Cath Maige Tuired along with Balor grandson of Nét, his rival and who may have been the king of the Inner Hebrides. Together they "gathered all the forces from Lochlainn westwards into Ireland to impose their tribute and their rule over them."
Various later rulers such as Gebeachan are also mentioned in early sources as having a role of some kind over unspecified areas of the northern part of the Kingdom of the Isles.

12th and 13th centuries
Kings of Mann and the Isles
|Ruler of the Hebrides & Mann||Period of Reign||Title||Notes|
|Magnus Barelegs||1098–1102||Possibly King of the Isles||Direct Norwegian rule|
|Sigurd Magnusson||1102–1103||Direct Norwegian rule||Nominal control by under-age son of Magnus Barelegs|
|Lagmann Godredsson||1103–1110||Eldest son of Godred Crovan|
|Domnall mac Taidc Uí Briain||1111–1112||Regent during the minority of Olave the Red||Nephew of Muirchertach Ua Briain. Expelled by the Islesmen.|
|Olave the Red||1112–1152||Son of Godred Crovan|
|Godred the Black||1154–1156||King of Man and the Isles||Son of Olave the Red|
|Somerled's sons & Godred the Black||1156–1158||Rulers of the southern islands and of Mann and the North Isles respectively.||Somerled's sons were Dubgall, Ragnall and Aonghas|
|Somerled||1158–1164||Lord of Argyll||Son-in-law of Olave the Red, his origins are otherwise obscure.|
Godred the Black's dictatorial style appears to have made him very unpopular with the Islesmen, and the powerful barons of the isles began plotting with an emerging and forceful figure – Somerled, Lord of Argyll. When Godred heard of this he engaged Somerled's forces in the naval Battle of Epiphany in 1156. There was no clear victor, but it was subsequently agreed that Godred would remain the ruler of Man and the northern Hebrides, whilst Somerled's young sons would nominally control the southern Inner Hebrides, Kintyre and the islands of the Clyde under their father's supervision. Two years later Somerled's invasion of the Isle of Man caused Godred to flee to Norway, leaving the former as undisputed ruler of the entire realm.
Following the death of Somerled in 1164 Godred re-took possession of his pre-1158 territories in Mann and the north and the southern isles were distributed amongst Somerled's sons as had been previously agreed: Dubgall received Mull, Coll, Tiree and Jura; Islay and Kintyre went to Ragnall; Bute to Aonghas, with Arran possibly divided between him and Reginald. The Chronicle of Man and the Sudreys lamented that Somerled's marriage to Ragnhildis, daughter of Olave the Red, had been "the cause of the ruin of the whole kingdom of the Isles".
Kings of Mann and the North Isles
|Kings of Mann||Norse name||Gaelic name||Period of Reign||Title||Notes|
|Reginald||Unknown||Unknown||1164||No record||Half-brother of Godred the Black|
|Godred the Black||Guðrøðr Óláfsson||Gofraid mac Amlaíb||1164–1187||King of the Isles||Re-instated|
|Ragnvald||Rögnvaldr Guðrøðarson||Raghnall mac Gofraidh||1188–1226||King of the Isles||Son of Godred the Black|
|Olaf the Black||Óláfr Guðrøðarson||Amlaíb mac Gofraid||1226–1237||King of Mann and the Isles||Half-brother of Raghnall mac Gofraidh|
|Óspakr-Hákon||Gille Escoib mac Dubgaill||1230||King of the Suðreyjar||Son of Dubgall mac Somairle?|
|Gofraid Donn||Guðrøðr Rögnvaldsson||Gofraid mac Ragnaill||1230||Son of Raghnall mac Gofraidh|
|Harald Olafsson||Haraldr Óláfsson||Aralt mac Amlaíb Duib||1237–1248?||King of Mann and the Isles||Son of Olaf the Black|
|Ragnvald Olafsson||Rögnvaldr Óláfsson||Ragnall mac Amlaíb||1249||King of Mann and the Isles||Son of Olaf the Black, his rule was brief|
|Harald Godredsson||Haraldr Óláfsson||Aralt mac Gofraid Donn||1249–1250||King of Mann||Son of Gofraid Donn and grandson of Raghnall mac Gofraidh|
|Magnus Olafsson||Magnus Óláfsson||Mágnus mac Amlaib||1252–1265?||King of Mann and the Isles||Son of Olaf the Black|
In a precursor to 1263, Norwegian forces invaded in 1230 in response to dynastic struggles amongst Godred the Black's descendants. The Chronicle of Lanercost states that a Norwegian fleet sailed down the west coast of Scotland with Óspakr-Hákon, who had been appointed "King of the Suðreyjar" by the King of Norway (and who may have been a son of Dubgall mac Somairle). His forces took Rothesay Castle, hacking through the walls with their axes. The Eirspennill version of Hákonar saga Hákonarsonar states that the fleet then sailed to Kintyre where Óspakr-Hákon fell ill and died. Olaf the Black then took control of the fleet, and led it to the Isle of Man. He and Gofraid Donn, the son of Raghnall mac Gofraidh, divided the kingdom between themselves, with the latter retaining Mann, and the former controlling the northern islands. A short time later Gofraid Donn was slain, possibly on Lewis.
On 30 May 1249, Ragnvald Olafsson was slain in a meadow near the Church of the Holy Trinity at Rushen by a knight named Ívarr, along with several of the knight's followers. The Chronicle of Lanercost states that he had reigned for only 27 days. Harald Godredsson then seized the kingship, although he was summoned to Norway the following year and effectively dispossessed. Magnus Olafsson was the last of the Norse kings to rule Mann, which was absorbed into the Kingdom of Scotland on his death.
Kings of the South Isles
|Rulers of the Hebrides||Gaelic name||Period of Reign||Title||Notes|
|Dugald||Dubgall mac Somairle||1164–c1175||King of the Isles||Son of Somerled|
|Ranald||Ragnall mac Somairle||1164–1207||King of the Isles||Son of Somerled|
|Duncan||Donnchadh mac Dubgaill||? – c. 1244?||King of the Sudreys||Son of Dubgall mac Somairle|
|Dugald Screech||Dubgall mac Dubgaill||?||King of the Sudreys||Son of Dubgall mac Somairle|
|Somerled||Somairle mac Dubgaill||? – 1230||King of the Sudreys||Probably a son of Dubgall mac Somairle|
|Ruari||Ruaidhri mac Raghnaill||1207?–1247?||King of the Isles||Son of Ragnall mac Somairle|
|Ewen of Argyll||Eóghan||1248–1263||King of the Sudreys||Son of Donnchadh mac Dubhghaill|
|Dugald MacRuairi||Dubhghall mac Ruaidhri||1249–1266?||King of the Sudreys||Son of Ruaidhri mac Raghnaill|
The 1780 Anecdotes of Olave the Black (which are based on Hákonar saga Hákonarsonar) state that there were 3 Sudreyan kings all existing at one time who were "of the family of Somerled" and who were "very untrue to King Haco". It is not entirely clear which three kings are being referred to. They include Dubgall "Screech" mac Dubgaill and his brother Donnchadh and either Eóghan of Argyll who "was king afterwards" or possibly an unknown "relation of theirs, called Somerled, [who] was then also a King in the Sudreys". This Somerled, who died in 1230, may have been a brother or cousin of Dubgall and Donnchadh.
Ragnall mac Somairle's son, Ruaidhri mac Raghnaill may have been the "king of the Isles" who was recorded in the Irish chronicles as having been killed fighting against the English at the Battle of Ballyshannon in 1247. Ruaidhri's direct descendents Dubhghall and Ailean, who ruled Garmoran and the Uists are generally not given titles by Scottish sources. However the Icelandic Annals recorded for the year 1249 that: "Dubhghall took kingship in the Sudreys." Norse sources also refer to kingship being held by Eóghan of Argyll, although this was rescinded by King Haakon when he refused to participate in the latter's expeditions against Scotland.

- Lord of Mann
- King of Mann
- Kings of Jorvik
- Lords of Galloway
- Duke of Argyll
- Ásbjǫrn skerjablesi, ninth-century Hebridean earl
- McDonald (2007) states of Raghnall mac Gofraidh: "Some of his successors were grandly styled Rex Manniae et Insularum, 'King of Man and the Isles' ", implying the title had not been used prior to that time, i.e. the early 13th century.
- This is the combined land area of the Isle of Man the islands of the Clyde, the Inner Hebrides and the Outer Hebrides.
- For consistency the regnal names up to the end of the reign of Somerled are as used by Gregory (1881) and by MacDonald (1997) for the period post 1164 unless otherwise indicated. MacDonald does not use patronymics unless otherwise indicated.
- Innsi Gall or in modern usage Innse Gall, meaning "islands of the foreigners or strangers", is a name originally used by mainland Highlanders when the Hebrides were ruled by the Norse and is still occasionally used by Gaelic speakers today to mean the Hebrides/Outer Hebrides.
- Amlaíb Conung was clearly a significant figure and a "king of the Northmen". The title "the greatest warrior king of the Western Sea" (or "West-over-the-sea") is recorded of Olaf the White in the Eyrbyggja Saga and some sources believe these two individuals are one and the same. Amlaíb may have pre-deceased Ímar.
- Ketill Flatnose appears in the Laxdœla saga, apparently set in the late ninth century. His daughter, Aud the Deep-Minded married Olaf the White, who some scholars believe to have been Amlaíb Conung, but these dates do not match well as Amlaíb is recorded as coming to Ireland in 853, unless a much earlier date for Ketill's excursions is accepted—which is also necessary for the validity of the proposed identification of Ketill with Caittil Find.
- There is no real evidence of Uí Ímair rule in the Isles during this period. For the following century the connection between the Hebrides, Man and Ireland "has been elucidated by Sean Duffy, who has demonstrated that, when control of Dublin passed to the Irish provincial kings in the middle of the eleventh century, these rulers also inherited the old Viking links between Dublin and the Isles".
- Crawford (1987) states that there was a possible "collapse of the earls' control in the west" following the Battle of Clontarf and there is no specific evidence that Einar ever claimed to be a ruler of the Suðreyar. He died c. 1025.
- Thorfinn is often stated as dying c. 1064, although Woolf (2007) states that "there is no reason why a date in the late 1050s is not just as credible."
- He may have "ruled Dublin and the Isles intermittently until 1061". However, if Echmarcach mac Ragnaill was a son of Ragnal mac Gofraid he must either have been very young when his father died in 1005, or very old on his own death in the early 1060s. He may have controlled Mann from 1036 onwards. There appears to be no evidence of his presence in or around the Scottish islands.
- Both possibilities for the timing of Lagmann Godredsson's reign have been advanced by modern scholars. For example, in 1986 Rosemary Power favoured the reigns of Lagmann and Domnall mac Taidc after Magnus's arrival, suggesting that Lagmann may have also ruled for a time under his overlordship. As noted above Duffy (1992) also placed Domnall mac Taidc Ua Briain's rule before Magnus.
- He is described as dominating "Dublin, and probably the Isle of Man and much of the coastline of Galloway and north west England."
- Woolf (2007) states of Amlaíb mac Gofraid: "It seems likely that he controlled or at least had strong influence in Man and Galloway."
- Amlaíb mac Gofraid was identified by the 12th century chronicler John of Worcester as "King of the Isles".
- Referred to by William of Jumièges as a king of the Swedes, Downham (2007) mentions a theory that "Lagmann ruled the Hebrides and Man in the early eleventh century", discussed further in Downham (2003.) .
