Sources The oldest account that may refer to Rognvald and the Earldom of Orkney appears to be the
Fragmentary Annals of Ireland. These annals are believed to date from the lifetime of Donnchad mac Gilla Pátraic, who died in 1039, although they survive only as incomplete copies made by
Dubhaltach Mac Fhirbhisigh (17th century). These events are placed after an account of the devastation of
Fortriu, dated to around 866, and the mention of an eclipse confirms a date of 865. Dating the
Orkneyinga saga has proven to be controversial but a recent analysis has the "majority of scholars in favour of dates between 1170 and 1220" whilst admitting that "it remains to be established when, why, where, for whom and by whom it was written". Much of the information it contains is "hard to corroborate". Rognvald is also referred to in
Snorri Sturluson's
Heimskringla (written c. 1230), written in Iceland. 's portrait of
Snorri Sturluson, 13th century compiler of the
Heimskringla. While the
Historia 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.
Family 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 in
Spain and
North 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 figure
Ragnar Lodbrok:
runic inscriptions found inside
Maeshowe, dating from the 12th century, state that the mound was "built before Loðbrók". The
Orkneyinga saga says that Rognvald was the son of
Eystein Ivarsson and grandson of Ívarr Upplendingajarl. He was married, according to the
Orkneyinga saga to Ragnhild, the daughter of a man named Hrólfr Nose, 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". Rognvald accompanied the king on a great military expedition. First the islands of Shetland and Orkney were cleared of
Vikings who had been raiding Norway and then continued on to Scotland,
Ireland and the
Isle of Man. During this campaign Rognvald's son Ivarr was killed and in compensation Harald granted Rognvald Orkney and Shetland. Rognvald thereafter returned to
Norway, giving the
northern isles to his brother
Sigurd Eysteinsson. Sigurd had been the
forecastleman on Harald's ship and after sailing back east the king "gave Sigurd the title of earl". According to the
Orkneyinga Saga, after Sigurd became earl he died in a curious fashion, following a battle with
Máel Brigte of Moray. Sigurd's son Gurthorm ruled for a single winter after this and died childless. 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." 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.
, as it appears in the 14th century Flateyjarbók''. 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 in
Iceland. 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." 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.
Historia Norvegiae includes some questionable details about pre-Viking Orkney – such as an account of the
Picts 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. This account does not specifically associate Rognvald with the earldom, attributing the "dominion" of the islands to the anonymous kinfolk of his son Hrólfr.
Death and legacy Rognvald was killed by King Harald's son
Halfdan 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 on
North Ronaldsay and then made peace with Harald. Rognvald's son Thorir was then made Earl of Møre by Harald, who also gave Thorir his daughter
Alof in marriage. 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 the
Dukes of Normandy who, following the
Norman conquest of England in 1066, became the
kings of England. ==Modern interpretations==
