Rognvald Eysteinsson (fl. 865) was the foundingJarl (or Earl) ofMøre inNorway, and a close relative and ally ofHarald Fairhair, the earliest known King of Norway. In theNorse language he is known asRǫgnvaldr Eysteinsson (Mǿrajarl) and in modernNorwegian asRagnvald Mørejarl. He is sometimes referred to withbynames that may be translated into modern English as "Rognvald the Wise" or "Rognvald the Powerful".

The earliest available sources regarding Rognvald are mutually contradictory and were compiled long after he died. The best known are theNorse Sagas, although modern scholars highlight many inconsistencies and improbable claims regarding Rognvald in the sagas, and believe that they must be treated with caution:^[2] The texts of the sagas were compiled three centuries after the events described and their accuracy in regard to Rognvald's life and historical significance is now questioned. Hence some scholars instead emphasise other accounts, closer to the historical period in question, such as Irish and Scottish sources.

While Rognvald does appear to have had some kind of role in the founding of the NorseEarldom of Orkney, most historians now doubt claims in the Sagas that Rognvald led one particular "great voyage" – a Norwegian expedition that attacked rebelvikings, who had been raiding Norway from bases onOrkney andShetland, before raiding theScottish mainland,Ireland and theIsle of Man. It is now generally believed that any such expedition would have occurred after Rognvald's lifetime. A modern authority onOrcadian history,William P. L. Thomson, comments that the story of the "great voyage is so thoroughly ingrained in popular and scholarly history, both ancient and modern, that it comes as a bit of a shock to realise that it might not be true."^[3]

Modern scholars also highlight inconsistencies and improbable claims in the sagas' claims regarding: the relationship between Rognvald and Harald; the names and biographies of Rognvald's immediate family; and, the founding of the earldom of Møre.

Rognvald was the father ofTorf-Einarr (d. circa 910) an earl of Orkney. Some Norse accounts claimed that another son, Hrólfr, settled in France and, under the nameRollo (d. 930), founded theDuchy of Normandy. However, French sources suggest that Rollo's father was an unnamedDanish or Norwegian nobleman, or a viking named Ketill.

The oldest account that may refer to Rognvald and the Earldom of Orkney appears to be theFragmentary Annals of Ireland. These annals are believed to date from the lifetime of Donnchad mac Gilla Pátraic, who died in 1039,^[4] although they survive only as incomplete copies made byDubhaltach Mac Fhirbhisigh (17th century).

These events are placed after an account of the devastation ofFortriu, dated to around 866,^[5] and the mention of an eclipse confirms a date of 865.^[6]

Dating theOrkneyinga saga has proven to be controversial but a recent analysis has the "majority of scholars in favour of dates between 1170 and 1220"^[7] whilst admitting that "it remains to be established when, why, where, for whom and by whom it was written".^[8] Much of the information it contains is "hard to corroborate".^[2]

Rognvald is also referred to inSnorri Sturluson'sHeimskringla (written c. 1230), written in Iceland.

While theHistoria Norvegiae (written c. 1505) includes an account of the foundation of the Orkney earldom, as well as some questionable details about pre-Viking Orkney, it has relatively little to say about Rognvald.

It is not certain that the Ragnall of the Irish annals is synonymous with Rognvald Eysteinsson. The relevant entry goes on to describe Ragnall's older sons raiding inSpain andNorth Africa, but there is no specific mention of the Earldom of Orkney. There is also a separate piece of circumstantial evidence, suggesting a link between Ragnall and the 9th century figureRagnar Lodbrok:runic inscriptions found insideMaeshowe, dating from the 12th century, state that the mound was "built before Loðbrók".^[6]

There is no agreement in the available sources on Rognvald's parentage. According to the Irish annals, Ragnall was the son of "Halfdan, King ofLochlann". This is generally understood to meanHalfdan the Black, which would make Ragnall the brother of KingHarald Fairhair. This is contradicted by later Norse sagas, which suggest that Halfdan was Rognvald's grandfather.^[9] TheOrkneyinga saga says that Rognvald was the son ofEystein Ivarsson and grandson of Ívarr Upplendingajarl.^[10]

He was married, according to theOrkneyinga saga to Ragnhild, the daughter of a man named Hrólfr Nose,^[11] although in theHeimskringla his wife is named Hild.^[12]

Both sagas refer to six sons. The oldest, "by concubines", were Hallad,Einarr and Hrollaug, who were "grown men when their brothers born in marriage were still children".^[11][12] The latter were Ivar, Hrólfr, andThorir the Silent. Hrólfr, who "was so big that no horse could carry him", hence his byname of "Ganger-Hrólf",^[11] (which means "by foot") is identified by the saga writers withRollo, founder of theDuchy of Normandy (in 911).^[12]

In theOrkneyinga saga Rognvald was made the Earl ofMøre byHarald Fairhair. TheSaga of Harald FairhairinHeimskringla recounts that Rognvald caused Harald Fairhair to be given his byname by cutting and dressing his hair, which had been uncut for ten years on account of his vow never to cut it until he was ruler of all Norway.^[13] Rognvald accompanied the king on a great military expedition. First the islands of Shetland and Orkney were cleared ofVikings who had been raiding Norway and then continued on to Scotland,Ireland and theIsle of Man. During this campaign Rognvald's son Ivarr was killed and in compensation Harald granted Rognvald Orkney and Shetland.

Rognvald thereafter returned toNorway, giving thenorthern isles to his brotherSigurd Eysteinsson.^[14][11] Sigurd had been theforecastleman on Harald's ship and after sailing back east the king "gave Sigurd the title of earl".^[11] However, theHeimskringla states specifically that Sigurd was the first Earl of Orkney.^[15] According to theOrkneyinga Saga, after Sigurd became earl he died in a curious fashion, following a battle withMáel Brigte of Moray. Sigurd's son Gurthorm ruled for a single winter after this and died childless.^[16][17] Rognvald's son Hallad then inherited the title. However, unable to constrain Danish raids on Orkney, he gave up the earldom and returned to Norway, which "everyone thought was a huge joke."^[18] Still, there is a tradition among the folk at Strath Halladale, Sutherland, which is named for Hallad, that he returned and was slain in battle at the beginning of the tenth century and was buried near the battle site in a circular trench ten or twelve feet wide. His sword, it is said, was placed beside him in the grave, and a stone was placed in the center of the circle, part of which was still visible at the beginning of the eighteenth century. The site was near a little town called Dal Halladha, Halladha's field.^[19]

The Danish raids caused Rognvald to fly into a rage and summon his sons Thorir and Hrolluag. He predicted that Thorir's path would keep him in Norway and that Hrolluag was destined seek his fortune inIceland. Turf-Einar, the youngest, then came forward and offered to go to the islands. Rognvald said: "Considering the kind of mother you have, slave-born on each side of her family, you are not likely to make much of a ruler. But I agree, the sooner you leave and the later you return the happier I'll be."^[20] His father's misgivings notwithstanding, Torf-Einarr succeeded in defeating the Danes and founded a dynasty which retained control of the islands for centuries after his death.^[21]

Historia Norvegiae includes some questionable details about pre-Viking Orkney – such as an account of thePicts as a small people who hid in the daytime – as well as the foundation of the Orkney earldom,.

In the days of Harald Fairhair, king of Norway, certain pirates, of the family of the most vigorous prince Ronald [Rognvald], set out with a great fleet, and crossed the Solundic sea..., and subdued the islands to themselves. And being there provided with safe winter seats, they went in summer-time working tyranny upon the English, and the Scots, and sometimes also upon the Irish, so that they took under their rule, from England,Northumbria; from Scotland,Caithness; from Ireland,Dublin, and the other sea-side towns.^[22]

This account does not specifically associate Rognvald with the earldom, attributing the "dominion" of the islands to the anonymous kinfolk of his son Hrólfr.^[23]

Rognvald was killed by King Harald's sonHalfdan Hålegg and Gudrod Gleam, who engineered a sudden attack, surrounding the house in which Rognvald was staying, and burned it to the ground with the earl and 60 of his men inside it. Harald "flew into a rage" when he heard about this and sent out a "great force" against Gudrod who was then banished. Halfdan escaped into the western seas and Rognvald's death was later avenged by Torf-Einarr, who killed him onNorth Ronaldsay and then made peace with Harald. Rognvald's son Thorir was then made Earl of Møre by Harald, who also gave Thorir his daughterAlof in marriage.^[24][25][26]

The sagas thus identify Rognvald as the apical figure of the Norse Earls of Orkney who controlled the islands until the early 13th century, and a forerunner of important Icelandic families. Furthermore, through his son Hrolfr, Rognvald is portrayed as an ancestor of theDukes of Normandy who, following theNorman conquest of England in 1066, became thekings of England.^[11]

Rognvald's life occurs within the first eight short chapters within theOrkneyinga saga and it is clear that in this early period it contains generally less detail and historical accuracy than in the later events it describes.^[28] Recorded in the 13th century, the sagas are informed by Norwegian politics of the day.

Harald Fairhair's supposed expeditions to the west, recounted by Snorri Sturluson inHeimskringla are no longer accepted as historical realities by many modern historians, including Thomson.^[3] Later (mid-13th century) rivalry between the Norwegians and theKings of the Scots over theHebrides and theIsle of Man are seen to have driven Sturluson's account.^[29] At least in part, the sagas aim to legitimise Norwegian claims to both the Northern Isles and theKingdom of the Isles in the west.^[27] The situation faced byEarl Harald Maddadsson of Orkney in 1195, when he was forced to submit himself to royal authority after an ill-judged intervention in Norwegian affairs, would have made legendary material of this nature of considerable interest in Orkney, at the time that the sagas were written.^[30]

It is also clear that elements in the narrative are drawn from the much later expeditions undertaken byMagnus Barefoot.^[27] Nonetheless, the view that the Orkney earldom was created by "members of the Møre family" continues to receive academic support.^{[31][Note 1]}

Harald Fairhair's victory in theBattle of Hafrsfjord, which gave him dominion over parts of Norway, is traditionally dated to 872, but was probably later, perhaps as late as 900.^[34] What little is known of Scottish events in the period from theChronicle of the Kings of Alba would correspond equally well with Harald's attacks on Scotland in the reign ofDomnall mac Causantín (ruled 889–900).^[35] However, this would not correspond with the sequence in the earliest account of the origins of the Orkney earldom, which places this a generation earlier. The entry in theFragmentary Annals at an early date also makes it difficult to reconcile the saga claims that Harald Fairhair was involved in Rognvald's conquest of the northern isles.

Other saga material provides an alternative description. In theEyrbyggja saga the same story of a great expedition to punish unruly Vikings who were raiding Norway is undertaken, but here it isKetilflatnefr (Ketil Flatnose) who leads it. Although this is apparently done at Harald's behest, Ketil then claims the islands as his own. Once again, the chronology is flawed by Harald's inclusion in the tale as other information provided about Ketil gives him afloruit of the mid, rather than late, 9th century.^[3]

Furthermore, contemporary Irish sources have a great deal to say about Viking raids on the coasts of Ireland and southern Scotland and those who led them, but none mention King Harald. The earliest of the large expeditions again belong to a period—the 840s—that pre-dates the time of Harald's kingship.^[36]

Smyth (1984) credits the launching of the great voyage to the west toOlaf the White, whom he provides with a royalVestfold origin along with various military activities in Scotland and for whom, assuming an identification of Olaf withAmlaib "Conung" theKing of Dublin, there is a contemporary Irish reference dating to 853.^[37] Icelandic sources also have Olaf marryingAud the Deep-Minded, Ketilflatnefr's daughter, and the ‘’Annals of Ulster’’ record what may be dynastic in-fighting between Olaf and his father-in-law in 857.^{[38][Note 2]}

By implication theOrkneyinga saga identifies Rognvald as the founder of the earldom, althoughHeimskringla has his brother Sigurd as the first to formally hold the title. Other sources are less specific (see above) and the sagas have been interpreted in various other ways. Smyth (1984), having banished King Harald’s role in the voyage to the west to the realms of myth concludes that the role of the brothers Eysteinsson can be similarly so dispatched and that Torf-Einarr “may be regarded as the first historical earl of Orkney”.^[40]

Drawing onAdam of Bremen's assertion that Orkney was not conquered until the time ofHarald Hardrada, who ruled Norway from 1043 to 1066, Woolf (2007) speculates thatSigurd “the Stout” Hlodvirsson, Torf-Einarr's great-grandson, may have been the first Earl of Orkney^[41]

The notion that Rognvald could hand over his Northern Isles estates to his brother has been interpreted in various ways. For example, it may be that he was aware of ongoing Viking raiding in the area and considered the gift from the king as a mixed blessing.^[42] This is also one of a number of instances in which the writer of theOrkneyinga saga attempts to reconcile the conflicting themes of independence from Norway (Rognvald gifts the islands to Sigurd) and dependence on royal authority (Harald formalises the process by confirming Sigurd as earl).^[43] Beuermann (2011) speculates that Rognvald's transfer of power to his brother may have been an attempt by the saga writers to imply that the Orkney earldom had more independence from Norway than that of Møre^[44] and that Rognvald's holdings in Caithness may have allowed for an even greater degree of freedom of action. Such implications are more likely to be rooted in the writer's interest in emphasising Orcadian independence at the time of writing rather than the 9th/10th century events they purport to describe.^[45]

After Hallad's failure in Orkney there is a dialogue between father and sons that has been interpreted as being about Rognvald's desire to cement his own position as Earl of Møre and an allusion to the early history of Iceland, where the sagas were written. Thorir is a compliant son who Rognvald is happy to keep at home. Hrollaug is portrayed as a man of peace who will go to Iceland. Einarr is aggressive and a threat to his father's position so can be spared for the dangers of Orkney.^[46] In theLandnámabók version the equally aggressive Hrolfr is also present, and his destiny is anticipated to be in conveniently far-awayNormandy.^{[47][Note 3]}

Alex Woolf suggests that saga authors may have synthesised elements of the life ofRagnall ua Ímair, a later figure, into the figure of Rognvald Eysteinsson of Møre. Ragnall ua Ímair, who was active between 914 and 921 in theIrish Sea region, was a grandson ofÍmar, the "king of the Northmen of all Britain and Ireland", whose death is recorded in theAnnals of Ulster in 873.^[48]

There are at least two major similarities between the two figures include: both are grandsons of an Ímar/Ivarr and; like Rognvald, a close relative of Ragnall named Ímar was killed in battle in Scotland (Ímar ua Ímair, d. 904).^[49]

There are several recurring themes in theOrkneyinga saga, including strife between brothers, relationships between the jarls and the Norwegian crown, and raiding in the Hebrides,^[50] all of which are touched on during the saga's coverage of Rognvald's life and times. In part, the saga's purpose was to "explore such social and psychological tensions as these in the history of the people of Orkney, and to help them understand themselves through a knowledge of their origins".^[51]
