as he appears on folio 9r of British Library Royal 14 C VII. Numerous sources reveal that, in the years following the ravaging of Mann and plundering of the Isles, Rǫgnvaldr bound himself closer to the English Crown. Whilst at
Lambeth on 16 May 1212, for instance, during what was likely his second visit to England in six years, Rǫgnvaldr formally swore that he was John's liegeman. Further corroboration is provided by the record, dated 16 May, concerning the release of some of Rǫgnvaldr's men who had been held in custody at
Porchester and
Dover. In another record, also dated 16 May, John authorised his
seneschals, governors, and
bailiffs in Ireland to come to Rǫgnvaldr's aid in the event that his territory was threatened by "'''' or others", since Rǫgnvaldr had bound himself to do the same against John's own enemies. The record of "''''" or
Vikings in this order may refer to the Norwegian raiders, like those who plundered the Isles in 1210. This particular source reveals that, not only was Rǫgnvaldr protected by John, but that he was also obligated to defend John's interests in the Irish Sea region. As such, Rǫgnvaldr's security was enhanced by English assistance, and John's influence was extended over the Isles at the expense of the Scots. , where Rǫgnvaldr was granted lands from the English Crown for the service of a knight. At the time, Carlingford was part of
Ulster, however today it located in
County Louth. Yet another transaction dated 16 May, in return for the homage and service that he rendered to the English Crown, Rǫgnvaldr and his heirs received a grant consisting of one knight's fee of land at
Carlingford, and one hundred measures of corn to be paid yearly at
Drogheda for the service of a
knight. The grant gave Rǫgnvaldr a valuable foothold in Ireland, and provided his powerful galley-fleet with an additional safe haven. The precise location of the territory granted to Rǫgnvaldr is unrecorded and unknown. Carlingford had until recently been a power centre of Hugh, and Rǫgnvaldr's grant may fit into the context of filling the power vacuum following the destruction of the Lacy lordship. Rǫgnvaldr's gifts from the English Crown may fit into the context of John attempting to offset interference from the
Philip Augustus, King of France. At about this time, the French Crown had orchestrated a Franco-Welsh alliance in an attempt to divert the English to deal with a Welsh uprising rather than focus their forces upon the Continent and
France in particular. In fact, there is evidence that
Norman ships were active off Wales in 1210. Although John had come to terms with Llywelyn ap Iorwerth in 1211, the following year the latter formed a concord with Philip. By May 1212, John succeeded in gaining the support of several foreign lords, such as the counts of
Bar,
Boulogne, and
Flanders, the dukes of
Brabant and
Limburg, the
Holy Roman Emperor, and Rǫgnvaldr himself. Despite these overtures, however, the Welsh uprisings of 1211 and 1212, as well as an English revolt in 1212, all succeeded in keeping English forces from invading France. At about the same time, several south-western Scottish magnates received grants in the north of Ireland. These included three of Rǫgnvaldr's Meic Fergusa kinsmen:
Alan fitz Roland, Lord of Galloway, Alan's brother
Thomas fitz Roland, Earl of Atholl, and Donnchad. Such grants appear to have been part of a coordinated campaign of the English and Scottish kings to gain authority over outlying territories where royal influence was limited. A record dated 3 January 1214 appears to confirm the English Crown's intentions of protecting the Islesmen, as it prohibits certain "mariners of Ireland" from entering Rǫgnvaldr's territories at his loss. The English pledges of protection of Rǫgnvaldr and his Irish holdings suggest that he was under immediate pressure at this period. It is possible, therefore, that the 1211/1212 seaborne devastation of
Derry by Thomas fitz Roland, and the unidentified sons of Ragnall—apparently
Ruaidrí and
Domnall—was undertaken in support of Rǫgnvaldr's interests in Ireland. In fact, Thomas fitz Roland and Ruaidrí ransacked Derry again in 1213/1214, and it is also possible that the raids were conducted in the interests of both the Scottish and English Crowns, and specifically aimed at limiting Irish support of the Meic Uilleim dissidents. If these attacks were indeed directed against political enemies of the Scottish and English Crowns, it is not improbable that Rǫgnvaldr and his forces were also involved. John died in October 1216, and was succeeded by his young son, Henry III. On one hand, the English summons of Rǫgnvaldr, dated 16 January 1218, in which he was ordered to amend certain "excesses" committed upon Henry III's men in Ireland and England, could be evidence that Islesmen took advantage of the somewhat fractured English realm by plundering the coasts of England and Ireland. If this was indeed the case, there is no further evidence of any such depredations. On the other hand, the "excesses" could specifically relate to an instance reported by the
Annals of Loch Cé, in which Irish
herring-fishermen are stated to have committed violence on Mann, and were slain as a consequence of their actions. Later in May, the English Crown commanded that Rǫgnvaldr was to be given safe passage to England in order account for the misconduct of his men. Whether Rǫgnvaldr actually travelled there that year is unknown, although various records reveal that he certainly did so the following year. Evidence of Rǫgnvaldr's activity in England survives in references of homage rendered to Henry III. One such record shows that, in late September, Rǫgnvaldr rendered homage to Henry III, and received the same fief that John had given him. In another record of his homage the English Crown added the qualification: "But if our enemies, or his, shall rebel against us, and him, to the loss of our or his land, then you are to be earnest in your help, for the defence of our land and of his, to our safety and convenience, so long as he shall keep himself faithful towards us". Therefore, whatever "excesses" Rǫgnvaldr's men had committed in the past, the surviving evidence reveals that by 1219 he was again amicably allied to the English king. ==Under the protection of the Pope==
