Rǫgnvaldr may have also used his journey as a means to safeguard the kingship against the claims of Óláfr. His presence there may explain his absence from Mann during the ravaging of the island by the English. In fact, Rǫgnvaldr's submission to Ingi could have been contributed to the English attack, as it may have given the English an incentive to devastate Rǫgnvaldr's lands because he had bound himself to John only a few years previous. Although John had originally installed Hugh as Earl of Ulster, he proceeded to dismantle the lordship after Hugh gave refuge to the Briouzes. The ravaging of Mann, therefore, may have been a further demonstration of English royal power directed at a disloyal vassal. If this was indeed the case, Rǫgnvaldr's submission to the Norwegian Crown—although apparently undertaken to safeguard his kingdom—clearly resulted in severe repercussions.
