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.
