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.
