Olaf the Black

Uncertain inheritance

Óláfr was a member of the Crovan dynasty, and a son of Guðrøðr Óláfsson, King of Dublin and the Isles. Óláfr's mother was Fionnghuala Nic Lochlainn. Guðrøðr had several other children: Affrica, Rǫgnvaldr, and Ívarr. Other possible children include Ruaidhrí, and a daughter whose name is unknown. According to the thirteenth-century Chronicle of Mann, Óláfr's mother was Fionnghuala Nic Lochlainn, granddaughter of Muirchertach Mac Lochlainn, High King of Ireland. She was probably a daughter of Muirchertach's son, Niall Mac Lochlainn, King of Cineál Eoghain. Although Óláfr's parentage is known, the maternal ancestry of Rǫgnvaldr is less certain. She may have been Sadbh, an Irishwoman identified as his mother by a contemporary Gaelic praise poem. The likelihood that Rǫgnvaldr and Óláfr had different mothers may well explain the intense conflict between the two men in the years that followed.

The chronicle reveals that the marriage between Guðrøðr and Fionnghuala was formalised in 1176/1177, under the auspices of a visiting papal legate. Before Guðrøðr's death in 1187, the chronicle claims that he left instructions for Óláfr to succeed to the kingship since the latter had been born "in lawful wedlock". This statement could indicate that Óláfr was born just before or immediately after his parents' marriage. The chronicle certainly states that Óláfr was born before the legate formalised his parents' marriage, suggesting that the union existed for some time prior. This source, however, gives conflicting dates for Óláfr's birth: 1173 and 1177. Specifically, in its account of his parents marriage, the chronicle states that Óláfr was three years old; and in its account of his father's death, Óláfr is said to have been only ten.

If the chronicle's account of Óláfr's stake in the kingship is to be believed, it could indicate that Guðrøðr attempted to legitimise the royal succession through his canonical marriage to Fionnghuala. However, this source appears to date to the reign of Óláfr's son, Magnús, and there is reason to suspect that it source was compiled in the context of an attempt to legitimise Óláfr's branch of the Crovan dynasty over that of Rǫgnvaldr. As such, the chronicle appears to be biased towards Óláfr's line, and its account of Guðrøðr's succession may not objective. Whether the chronicle is accurate in its account of the succession is uncertain, as the Islesmen are stated to have chosen Rǫgnvaldr to rule instead, because unlike Óláfr, who was only a child at the time, Rǫgnvaldr was a hardy young man fully capable to reign as king. Furthermore, the fact that Rǫgnvaldr appears to have held power in the Hebrides at the time of Guðrøðr's death could indicate that it was Rǫgnvaldr who had been the acknowledged heir. Another possibility, suggested by the chronicle and latter correspondence between Óláfr and the English Crown, is that Rǫgnvaldr's tenure had been originally intended as temporary wardship until Óláfr was able to reign himself.

Hebridean magnate

Rǫgnvaldr succeeded Guðrøðr as king in 1188. At some point after assuming control of the kingdom, the chronicle reports that Rǫgnvaldr gave Óláfr possession of a certain island called "Lodhus". The chronicle disparagingly describes the island as being mountainous and rocky, completely unsuitable for cultivation, and declares that its small population lived mostly by hunting and fishing. Although Lodhus is an early Latin form of the place name of Lewis—the rather flat and boggy northerly half of the Outer Hebridean island of Lewis and Harris—the chronicle's text seems to instead refer to Harris—the somewhat mountainous southerly half. The chronicle claims that, because of the impoverishment of his lands, Óláfr was unable to support himself and his followers, and that in consequence he led "a poor sort of life". There is reason to suspect that the chronicle's otherwise perceptible prejudice against Rǫgnvaldr's branch of the Crovan dynasty, and its apparent bias in favour of Mann over the northernmost reaches of the realm, may also account for its denigrating depiction of Óláfr's allotted lands.

In consequence of this supposed poverty, the chronicle claims that Óláfr went to Rǫgnvaldr, who was also living in the Hebrides, and confronted him for more land. Rǫgnvaldr's stated response was to have Óláfr seized and sent to William I, King of Scotland, who kept him imprisoned for almost seven years. It is possible that, at this stage of his career, Óláfr acted as an under-king to Rǫgnvaldr, and sought to increase his share of power. There is reason to suspect that, following Óláfr's inability to make a deal with Rǫgnvaldr, Óláfr approached Ingi Bárðarson, King of Norway, and offered himself as a more palatable vassal-king in return for Norwegian support in deposing Rǫgnvaldr. In 1210, Rǫgnvaldr himself appears to have travelled to Norway, as evinced by a version of the thirteenth-century Bǫglunga sǫgur, in a journey that could well have been an attempt to further cement his position in the Isles, and counter Óláfr's claims to the throne, by formally submitting to the Norwegian king. In any case, the chronicle states that William died during the seventh year of Óláfr's captivity, and that William had ordered the release of all his political prisoners before his passing. Since William died in December 1214, Óláfr's incarceration appears to have spanned between about 1207/1208 and 1214/1215. Upon his release, the chronicle reveals that the half-brothers met on Mann, after which Óláfr set off on a pilgrimage with his followers to Santiago de Compostela.

Óláfr's time in the Isles is confirmed by several Icelandic sources—the sagas of Hrafn Sveinbjarnarson (an Icelandic chieftain) and Guðmundr Arason (an Icelandic ecclesiast)—which recount how, in 1202, Guðmundr attempted to sail from Iceland to Norway to become consecrated as the Bishop of Hólar. For example, the thirteenth-century Hrafns saga Sveinbjarnarsonar relates that the wayfaring Icelanders encountered a severe storm and were blown far off course before being forced to make landfall in the Hebrides. The saga identifies the island they landed upon as Sandey, which may well refer to Sanday, a tiny tidal island linked to its larger neighbour Canna, the westernmost island of the Small Isles. The sandy flat that joins the islands together forms one of the best natural harbours in the Hebrides.

Marriage to Lauon

Upon Óláfr's return from his pilgrimage, the chronicle records that Rǫgnvaldr had Óláfr marry "Lauon", the sister of his own wife. Rǫgnvaldr then granted Lodhus back to Óláfr, where the newly-weds proceeded to live until the arrival of Reginald, Bishop of the Isles. The chronicle claims that the bishop disapproved of the marriage on the grounds that Óláfr had formerly had a concubine who was a cousin of Lauon. A synod was then assembled, after which the marriage is stated to have been nullified.

Although the identity of the half-brother's father-in-law is uncertain, the chronicle describes him as a nobleman from Kintyre, which suggests that he was a member of Clann Somhairle, since sources concerning this kindred associate it with Kintyre more than any other region. As such, the father could have been either Raghnall mac Somhairle, or Raghnall's son, Ruaidhrí—both of whom appear to have been styled "Lord of Kintyre" in contemporary sources—or possibly even Raghnall's younger son, Domhnall.

It is conceivable that Rǫgnvaldr's marriage was undertaken before 1210, perhaps not long after 1200 considering the fact that Guðrøðr Dond—a product of this union—was an adult by 1223 and had fathered at least one son by this date. Óláfr's marriage to Lauon may have taken place in 1216. The binding of Rǫgnvaldr and Óláfr to Clann Somhairle wives could well have been orchestrated in an effort to patch up relations between the Crovan dynasty and Clann Somhairle, neighbouring kindreds that had bitterly contested the kingship of the Isles for about sixty years.

After the death of Aonghus mac Somhairle in 1210, the leading dynast of Clann Somhairle appears to have been Ruaidhrí. It is possible that, as a result of the marriage alliance between his family and the Crovan dynasty, Ruaidhrí acknowledged Rǫgnvaldr's kingship, and thereby established himself as a leading magnate within a reunified Kingdom of the Isles. Since the majority of Ruaidhrí's territories appear to have been mainland possessions, it is very likely that the Scottish Crown regarded this alliance and apparent reunification of the Isles as a threat to its own claims of overlordship of Argyll. In fact, it is possible that the Scots' release of Óláfr in 1214 was intended to cause dynastic discord in the Isles. If this was indeed the case, the reconciliation between the half-brothers ensured that the Scottish Crown's machinations came to nought—at least temporarily.

Marriage to Cairistíona

Once freed from his arranged marriage to Lauon, the chronicle reports that Óláfr proceeded to marry Cairistíona, daughter of Fearchar mac an tSagairt. The union appears to have taken place in about 1222/1223. The father of Cairistíona emerges from historical obscurity in 1215. Seemingly by the mid 1220s—at about the time of Cairistíona and Óláfr's marriage—Alexander II, King of Scotland rewarded Fearchar with the Earldom of Ross for meritorious service to the Scottish Crown. Although it is unknown if Fearchar received the earldom before his daughter's marriage, his comital elevation—or foreknowledge of it—could well have precipitated the match.

There is certainly reason to suspect that the collapse of Óláfr's marriage to Lauon, and his subsequent marriage to Cairistíona, was a politically motivated maneuver. In 1221/1222, Alexander seems to have overseen a series of invasions into Argyll. This royal campaign appears to have resulted in a local regime change, with Ruaidhrí being replaced by Domhnall in Kintyre. One of several factors that could account for Ruaidhrí's expulsion is Scottish apprehension of a rejuvenated Kingdom of the Isles.

Immediately after its account of Óláfr's marriage to Cairistíona, the chronicle details outright conflict between Óláfr and Rǫgnvaldr's family. The fact that this outbreak of violence is specifically dated to 1223 could indicate that it was Ruaidhrí's apparent downfall in Kintyre that led Óláfr to realign himself with Fearchar. By linking himself with Fearchar, Alexander's leading lieutenant in the north, it would appear that Óláfr recognised a regional shift in power, and therefore attempted to bind himself to a rising star in Scotland, and extract himself from any liability connected to Lauon's kin. Another apparent aftereffect of the Scots' invasion of Kintyre was the creation of the Clann Dubhghaill Lordship of Argyll, first evinced in 1225. If members of the Clann Dubhghaill branch of Clann Somhairle indeed began operating as agents of the Scottish Crown at about this time, it is possible that Óláfr—as a rival to the ruler of a reformed Kingdom of the Isles—acted as an agent of Scottish interests as well. As such, Óláfr's marriage to Cairistíona may have ultimately stemmed from a Scottish desire to destabilise the Isles. If Lauon's father was indeed Ruaidhrí, it is possible that Óláfr compensated the latter for his marriage by granting him lands or protection in the Isles. It is also possible that Ruaidhrí's descendants—Clann Ruaidhrí—owed their later power in Garmoran and the Hebrides to Óláfr's patronage.

Conflict with Guðrøðr Dond

If the chronicle is to be believed, Óláfr's separation from Lauon enraged her sister—the wife of Rǫgnvaldr and mother of Guðrøðr Dond—who surreptitiously tricked Guðrøðr Dond into attacking Óláfr in 1223. Following what he thought were his father's orders, Guðrøðr Dond gathered a force on Skye—where he was evidently based—and proceeded to Lodhus, where he is reported to have laid waste to most of the island. Óláfr is said to have only narrowly escaped with a few men, and to have fled to the protection of his father-in-law on the mainland in Ross. Óláfr is stated to have been followed into exile by Páll Bálkason, a vicecomes on Skye who refused to take up arms against him. At a later date, Óláfr and Páll are reported to have returned to Skye and defeated Guðrøðr Dond in battle.

The chronicle specifies that Guðrøðr Dond was overcome on "a certain island called the isle of St Columba". This location may be identical to Skeabost Island in the mouth of the river Snizort (NG41824850). Another possibility is that the isle in question is the now-landlocked island of Eilean Chaluim Chille in the Kilmuir district (NG37706879). This island once sat in Loch Chaluim Chille before the loch was drained of water and turned into a meadow. There is archaeological evidence to suggest that a fortified site sat on another island in the loch, and that this islet was connected to the monastic island by a causeway. If correct, the fortification could account for Guðrøðr Dond's presence near an ecclesiastical site. According to the chronicle, Óláfr's forces consisted of five boats, and encircled the island after having launched from the opposite shore two stadia from it. This distance, about 2 furlongs (400 metres), suggests that the island is more likely Eilean Chaluim Chille than Skeabost Island, as the former appears to have sat between 285 metres (935 feet) and 450 metres (1,480 feet) from the surrounding shores of Loch Chaluim Chille. In any case, following the clash, the chronicle reports that Guðrøðr Dond's captured followers were put to death, and Guðrøðr Dond was blinded and castrated. It is possible that Óláfr was aided by Fearchar in the strike against Guðrøðr Dond. Certainly, the chronicle's account seems to suggest that Óláfr accumulated his forces whilst sheltering in Ross. Although the chronicle maintains that Óláfr was unable to prevent this torture, and specifically identifies Páll as the instigator of the act, the Icelandic annals record that Óláfr was indeed responsible for his nephew's plight, and make no mention of Páll.

The mutilation and killing of high-status kinsmen during power-struggles was not an unknown phenomenon in the peripheral-regions of the British Isles during the High Middle Ages. For instance, in only the century-and-a-half of its existence, at least nine members of the Crovan dynasty perished from mutilation or assassination. As such, there is reason to regard this vicious internecine violence as the Crovan dynasty's greatest weakness. To contemporaries, the tortures of blinding and emasculation were a means of depriving power from a political opponent. Not only would the punishment deny a man the ability to sire descendants, it would divest him of personal power, limiting his ability to attract supporters, and further offset the threat of future vengeance. The maiming inflicted upon Guðrøðr Dond seems to exemplify Óláfr's intent to wrest his perceived birthright from Rǫgnvaldr's bloodline. It is unknown why Rǫgnvaldr did not similarly neutralise Óláfr when he had the chance years before, although it may have had something to do with the preservation of international relations. For example, it is possible that his act of showing leniency to Óláfr had garnered Scottish support against the threat of Norwegian overlordship. In any case, the neutralisation of Guðrøðr Dond appears to mark a turning point in the struggle between Óláfr and Rǫgnvaldr.

Opposition from Alan fitz Roland

In 1224, the year following the defeat of Rǫgnvaldr's son, the chronicle reveals that Óláfr took hostages from the leading men of the Hebridean portion of the realm, and with a fleet of thirty-two ships, landed on Mann at Ronaldsway, where he confronted Rǫgnvaldr directly. It was then agreed that the kingdom would be split between the two: with Rǫgnvaldr keeping Mann itself along with the title of king, and Óláfr retaining a share in the Hebrides. With Óláfr's rise at Rǫgnvaldr expense, the latter turned to Alan, one of Scotland's most powerful magnates. Alan and Rǫgnvaldr were certainly closely connected. Both were great-grandsons of Fergus, Lord of Galloway; both had received Ulster lands from the English at about the same time; and it is possible that connections between the Isles and Galloway had led to Rǫgnvaldr's involvement with the Scottish Crown in Caithness in about 1200.

In a letter from Alan to Henry, dated the year of the partitioning between the half-brothers, Alan mentioned that he was preoccupied with his army and fleet, travelling from island to island. This statement could well evince the beginning of joint military operations, conducted by Alan and Rǫgnvaldr against Óláfr, assigned by the chronicle to the following year. According to the latter source, however, the campaigning came to nought because the Manx were unwilling to battle against Óláfr and the Hebrideans. This record appears to show that Alan portrayed his actions in the Isles as related to his conflict with the Lacys in Ireland. As such, the correspondence could be evidence that the Ulster ambitions of Hugh de Lacy were aligned with Óláfr in the Isles. Not only did Óláfr clash with Rǫgnvaldr's son in 1223, but Hugh launched a bid to recover his forfeited Earldom of Ulster in the same year, a reclamation that seriously threatened recent Gallovidian expansion in Ireland. Whilst Rǫgnvaldr clearly had the support of Alan and his family, there is reason to suspect that Óláfr was allied to Hugh. In the correspondence between Alan and Henry, Alan stated that he had been on the verge of launching an invasion of Ireland when he learned of an agreement reached between Hugh and the Justiciar of Ireland, and therefore sought the king's confirmation of his family's lands in Ulster. Alan's letter appears to show that his campaigning in the Isles was understood to have been a detriment to Hugh in Ireland. As such, Hugh seems to have been expected to make use of military assistance from Isles in his restoration attempt. Óláfr's move against Rǫgnvaldr in 1223 and 1224—the very time the Lacys campaigned against Gallovidian interests in Ireland—is unlikely to have been a coincidence. It may have been the window of opportunity that Óláfr seized upon. Alternately, it may have been Hugh himself who capitalised upon the Gallovidian's campaigning against Óláfr.

Rǫgnvaldr's final fall

In what was likely early January 1229, the chronicle records that Rǫgnvaldr caught the forces of Óláfr unaware, as Rǫgnvaldr sailed from Galloway with five ships, and launched a nocturnal raid upon the harbour at St Patrick's Isle, near what is today the town of Peel. During this assault, the chronicle records that Rǫgnvaldr had all of the ships of Óláfr and his chieftains destroyed. Although the chronicle's description of the attack alludes to Gallovidian involvement, as it states that the expedition originated from Galloway, the fact that Rǫgnvaldr commanded only five ships suggests that this support may have been waning.

Rǫgnvaldr followed up on his assault by establishing himself in the southern part of Mann, as the chronicle records that he won over the support of the southerners. Meanwhile, Óláfr is stated to have assembled his forces in the north of Mann, indicating that the island was divided between the two men for much of January and February, before what would be their final confrontation. According to the chronicle, Rǫgnvaldr and Óláfr led their armies to Tynwald. The derivation of this place name—from the Old Norse elements þing ("assembly") and vǫllr ("field", "meadow")—reveals that it was an assembly site, which in turn suggests that negotiations may have been intended.

On 14 February, the festival of St Valentine, the chronicle records that Óláfr's forces launched an attack upon Rǫgnvaldr at Tynwald, where Rǫgnvaldr's troops were routed and he himself was slain. Tynwald may well have been the place where the Islesmen publicly inaugurated their kings, proclaimed new laws, and resolved disputes. As such, Óláfr's victory over Rǫgnvaldr at this site could have enhanced his royal status. Whilst Rǫgnvaldr's fall is laconically corroborated by the Icelandic annals, other sources appear to suggest that his death was due to treachery. The fourteenth-century Chronicle of Lanercost, for example, states that Rǫgnvaldr "fell a victim to the arms of the wicked"; whilst the Chronicle of Mann states that, although Óláfr grieved at his half-brother's death, he never exacted vengeance upon his killers. Although the latter's account of Guðrøðr Dond's maiming and Rǫgnvaldr's death could be evidence that Óláfr was unable to control his supporters during these historical episodes, it is also possible that the compilers of this source sought to disassociate Óláfr from these acts of violence against his kin.

Norwegian intervention

Óspakr's appointed kingship

The death of Alan's ally did not deter Gallovidian interests in the Isles. In fact, it is apparent that Alan and members of the Clann Dubhghaill branch of Clann Somhairle upheld pressure upon Óláfr. Reports of open warfare in the Isles reached Hákon's royal court in the summer of 1229. The thirteenth-century Hákonar saga Hákonarsonar specifically singles out Alan as one of the principal perpetrators of unrest, describing him as "the greatest warrior", possessing a large force of men and ships with which he plundered throughout the Hebrides. Several members of Clann Somhairle are also associated with this unrest: Dubhghall mac Dubhghaill, Donnchadh mac Dubhghaill, and a certain Somhairle. Whilst these members of Clann Somhairle are depicted as being disloyal to Hákon, the saga contrasts them with Óláfr, who is said to have been a steadfast supporter of Hákon, and to have manfully held his kingdom against Alan.

Although Óláfr arrived at the Norwegian court early in 1230, having been forced from the Isles by Alan and his allies, it is evident that Hákon had already decided upon a course of action. Upon his arrival, the saga relates that Óláfr gave a report of Alan's actions in the Isles. According to the Flateyjarbók and Skálholtsbók versions of the saga, Óláfr repeated a boast of Alan, suggesting that Alan thought himself capable of even invading Norway. Rather than being an accurate reflection of Alan's intentions, however, there is reason to suspect that Óláfr's recounted bluster was instead an invention designed to direct further Norwegian animosity at Alan.

In any case, the Icelandic annals, saga, Chronicle of Mann, and Chronicle of Lanercost all reveal that Hákon handed over the kingship of the Isles to Óspakr, an apparent member of Clann Dubhghaill who had long served outside the Isles in Norway. Other Islesmen in Norway before Óláfr's arrival were Páll and Guðrøðr Dond, the latter who seems to have been one of Óspakr's principal supporters. According to saga, Hákon not only granted Óspakr the kingship, but also gave him command of the Norwegian fleet tasked with restoring peace in the Isles.

Within days of Óláfr's arrival in Norway, the saga reveals that Óspakr's fleet set sail for the Isles, and swelled in number after reaching Orkney. Whilst the Eirspennill version of the saga numbers the fleet in Norway at twelve ships, the Flateyjarbók, Frísbók, and Skálholtsbók versions give the number eleven; and whilst the former version relates that the fleet gained twenty ships from Orkney, the latter three versions state that the fleet numbered twenty when it left Orkney. The saga recounts that Óláfr and Páll journeyed on the same ship, and states that, after they reached Orkney, Jón Haraldsson, Earl of Orkney gave Óláfr a ship called the Ox. Once in the Isles, the fleet linked up with three leading members of Clann Somhairle on Islay.

Óláfr and Guðrøðr Dond's shared kingship

In consequence of Óspakr's fall, the saga reveals that command of the fleet was assumed by Óláfr, who successfully eluded Alan's forces by leading the force to the Kaupmannaeyjar ("Merchant Islands"), a group of islands which appear to refer to the Copeland Islands. There is reason to suspect that this destination, just off the Ards Peninsula, was chosen in an effort to acquire both protection and provisioning. Specifically, the islands may have provided the fleet with the ability to prevent Alan—who was married to a daughter of Hugh—from drawing assistance from Ireland. It is also conceivable that the fleet procured logistical support from nearby Grey Abbey, a monastery founded by Óláfr's sister, Affrica. Another nearby religious house, Inch Abbey, founded by Affrica's husband, (Hugh's predecessor in Ulster) John de Courcy, could have also provided the fleet with provisions. After the fleet's stay at the Kaupmannaeyjar, the saga relates that it set sail for Mann, where a force of Manxmen led by a certain Þórkell Njálsson—an apparent Islesman who may have been allied to the Gallovidians—briefly resisted the incomers before being dispersed. According to the Chronicle of Lanercost and Chronicle of Mann, after having reached Mann, Óláfr and Guðrøðr Dond divided the kingdom between themselves, with Óláfr controlling Mann and Guðrøðr Dond the islands.

Despite Óspakr's elevation as king, it is uncertain how Hákon envisioned the governance of the Kingdom of the Isles. On one hand, it is possible that Hákon intended for Óspakr and Guðrøðr Dond to divide the kingdom at Óláfr's expense. On the other hand, the fact that Óláfr's struggle against Alan and Clann Somhairle is acclaimed by the saga could be evidence that Hákon did not intend to replace Óláfr with Óspakr. Instead, Hákon may have planned for Óspakr to reign over the sprawling domain of Clann Somhairle as a way to ensure the kindred's obedience. Óspakr's prospective realm, therefore, seems to have comprised Argyll, Kintyre, and the Inner Hebrides. If correct, the fleet's primary design would appear to have been the procurement of Óspakr's domain, whilst a secondary objective—adopted very late in the campaign—seems to have been the restoration of Óláfr on Mann.

It is also possible that Hákon originally ordered a division of power between Óláfr and Guðrøðr Dond, and that Hákon originally promised to lend support to Óláfr's cause on the condition of a concession of authority to Guðrøðr Dond, who—like Óspakr—could have been recognised as king by the Norwegian Crown. An accommodation between Óláfr and Guðrøðr Dond could well have benefited both men, as it would have safeguarded their kindred against the dynastic ambitions of Alan, offsetting the royal marriage between this man's son and Guðrøðr Dond's sister. There is certainly no further record of Alan pursuing military actions against Óláfr, which could be evidence that Alan came to terms with an arrangement between the two competing branches of the Crovan dynasty.

Later reign

After the campaign of 1230/1231, Alan ceased his policy of aggression against Óláfr, probably on account of Alexander, who afterwards pursued a more measured strategy dealing with the Norse-Gaelic magnates on the northwestern periphery of his realm. There is no evidence that Óláfr ever threatened the Scots after finally regaining authority. It is possible that he actually owed his release in about 1214 to Alexander himself. It may have been that, after his resumption of power in 1230/1231, the Scots failed to disturb him and he did not disturb them. In the context of the campaign of 1230/1231, the Norwegians appear to have regarded Alan as their main opponent, not Alexander. It is possible that the latter regarded Alan's ambitions in the Isles, and his warring against Óláfr, as a root cause of the crisis faced by the Scots that year. In any case, Alexander afterwards appears to have relied upon Walter fitz Alan II, Steward of Scotland, and the latter's kin, to extend Scottish royal authority into Argyll and the Isles. It was not until the 1240s that the Scots resumed aggressive actions in the west.

At some point during his reign, he is known to have granted certain commercial rights and protections to the monks of Holm Cultram Abbey. At one point he granted rights to the priory of Whithorn concerning two churches on Mann (St Ninian at Ballacgniba and St Ronan), and at another point granted the priory of St Bees sixty head of cattle or the equivalent value in sheep or swine. Óláfr's 1228 letter to Henry reveals that Óláfr involved himself with mercantile activity.

In 1235, Óláfr journeyed to the court of Henry, as evidenced by an English letter of safe passage issued in April 1235. That July, Óláfr is recorded to have rendered homage to Henry, and to have received payment for his services in safeguarding the English and Irish coasts for the English Crown. As a result, Óláfr pledged to secure the English and Irish coasts faithfully, and to supply the English with fifty galleys when needed: all for the annual allowance of forty marks, one hundred crannocks of wheat, and five hogsheads of wine.

Near the end of his reign, Óláfr appears to have commenced another visit to Norway, as evidenced by directives of Henry instructing his subjects to protect Óláfr and his kingdom during his absence (issued in May 1236, and April 1237).

Óláfr may have been a patron of St German's Cathedral on St Patrick's Isle, as the chronicle reports that this religious house was constructed by Simon, Bishop of the Isles. The site itself appears to have been established in the twelfth- or thirteenth century. Early diocesan bishops, during the eleventh and twelfth centuries, may well have circulated from region to region in the Isles, and it is possible that the cathedral's foundation represents the final settling of the diocesan see. The site has undergone several phases of construction over the centuries, and it is uncertain what part can be credited to Simon. Óláfr's actions in the northern Hebrides could indicate that he was also a patron of the Snizort Cathedral on Skeabost Island, a religious house that first appears on record in the fourteenth century.

Death

Óláfr's reign spanned from 1226 to 1237. Although a significant portion of the Chronicle of Mann is devoted to the strife between him and Rǫgnvaldr, the span of Óláfr's reign is covered in only a few lines. According to this source Óláfr died on 21 May 1237, on St Patrick's Isle, and was buried at Rushen Abbey. This monastic house, the foremost ecclesiastical site on Mann, had originally been founded by his paternal grandfather in 1134. By the thirteenth century, it served as a royal mausoleum of the Crovan dynasty, being the burial place of three of the family's four kings that ruled between 1226 and 1265. Óláfr was the first royal to be laid to rest at Rushen. The others were his sons Rǫgnvaldr, and Magnús. There is a possibility that a thirteenth-century stone coffin-lid or grave-slab found at Rushen may be associated with one of the three kings buried there. The fact that Óláfr and his father died on St Patrick's Isle suggests that it was a royal residence. It is possible that the seat of Manx royal power was located at Peel Castle, on St Patrick's Isle, before the seat moved to Castle Rushen in the thirteenth century.

Descendants

Óláfr was survived by three children: Haraldr, Rǫgnvaldr, and Magnús—all of whom eventually ruled as kings. Óláfr was succeeded by his son, Haraldr, who was in turn succeeded by Óláfr's son, Rǫgnvaldr. This monarch was slain in 1249, seemingly by an associate of Guðrøðr Dond's son, Haraldr, whereupon the latter assumed the kingship. This abrupt seizure of royal power by Guðrøðr Dond's son—almost twenty years after Guðrøðr Dond's death—exposes the fact that the inter-dynastic strife between lines of (Guðrøðr Dond's father) Rǫgnvaldr and Óláfr carried on for yet another generation. The infighting only came to an end in the reign of the dynasty's final monarch, Óláfr's son, Magnús.

The mother of Óláfr's children is uncertain. Although no source names the mother of his son, Haraldr, the chronicle asserts that the latter was only fourteen years old at the time of Óláfr's death. This would place Haraldr's birth in 1222 or 1223, at about the time that Óláfr married Cairistíona, which indicates that either Cairistíona or Lauon could have been Haraldr's mother. As for Haraldr's two succeeding brothers, it is conceivable that Cairistíona was their mother. If Lauon was indeed the mother of Haraldr and a descendant of Raghnall, this relationship could explain why Ruaidhrí and Domhnall—apparently close adherents of Óláfr's half-brother, Rǫgnvaldr—are not recorded to have opposed Óláfr after Rǫgnvaldr's death. Certainly, the recorded history of the Isles between the 1230s and 1240s is remarkably peaceful in comparison to other eras.

There is evidence to suggest that Óláfr had a fourth son, Guðrøðr. For example, the chronicle relates that, not long after Haraldr's succession, Haraldr visited the Hebrides and left control of Mann to Lochlann, his kinsman who governed the island in his place. In the following autumn, Lochlann and his supporters are said to have come into conflict with Hebridean supporters of Haraldr, and when the latter returned to Mann in the spring, the chronicle reports that Lochlann fled to Wales with all his men and his foster son, a youth identified as Guðrøðr, the son of a man named Óláfr. The ship they were travelling on is stated to have been wrecked upon the Welsh coast, and although Lochlann was able to make it ashore safely, he returned to the scene in an attempt to save Guðrøðr. According to the chronicle, Lochlann, Guðrøðr, and about forty others lost their lives in the shipwreck.

It is possible that Lochlann's foster son is identical to a similarly named individual, a certain "Godredo filio regis Mannie", who attested a quitclaim between Llywelyn ap Gruffudd and Ralph de Mortimer, in about 1241. It is uncertain what compelled Lochlann to flee his sovereign, and it is uncertain why he chose Wales as his destination. The Crovan dynasty certainly had diplomatic and familial connections with the Welsh. One possibility is that the account of Lochlann's flight reveals that he attempted to replace Óláfr's son, Haraldr, with another son. If the chronicle is incorrect in its account of the foster-son's maritime demise, and he is indeed identical to the like-named Manx prince attested in Wales, this individual's activities outside the realm of his ancestors may have been a consequence of strife following Óláfr's death and Haraldr's accession. Haraldr's young age at the time, and the fact that he had a potential rival in the person of his like-named cousin, Haraldr Guðrøðarson, could indicate that Haraldr had been designated as successor during his father's lifetime.
