The kin-strife largely took place on Skye and Lewis and Harris, islands that were clearly important within the kingdom. In fact, there is evidence to suggest that the kingdom's northern territories were granted by reigning kings to heir-apparents or disaffected dynasts. For example, during the eleventh-century reign of the dynasty's founder, Guðrøðr Crovan, the northern portion of the realm may have been governed by Guðrøðr Crovan's succeeding son, Lǫgmaðr. The fact that Rǫgnvaldr was residing in the Hebrides when his father died in 1187 may indicate that, despite the chronicle's claims to the contrary, Rǫgnvaldr was indeed the rightful heir to the kingship. Furthermore, since Rǫgnvaldr's son is recorded on Skye, the possibility exists that he resided there as his father's heir-apparent. Rǫgnvaldr's grant of Lewis and Harris to Óláfr may, therefore, indicate that Óláfr was at least temporarily regarded as Rǫgnvaldr's rightful successor. On the other hand, it is also possible that Rǫgnvaldr's grant was given in the context of appeasing a disgruntled dynast passed over for the kingship. In any event, it is apparent that such territorial fragmentation would have severely weakened the realm.
