 The campaign is regarded to have been the gravest threat to the Scottish kingdom since John, King of England's (d. 1216) northern campaigning and invasion in 1216. Although Óláfr's restoration on Mann was claimed as a success by the Norwegians, it was probably accepted gladly by the Scots as well; considering Óláfr's familial relationship with Alexander's protégé Ferchar and the consolidation of the Crovan dynasty after years of chaos. Óláfr consequently ruled the Kingdom of Mann and the Isles peacefully until his death, seven years later. The chronicle states that he died on St Patrick's Isle on 21 May 1237 and was buried at St Mary's Abbey, Rushen. There is a possibility that a coffin-lid or grave-slab found at Rushen may be associated with Óláfr, or of two of his sons who are known to have been buried there (Rögnvaldr and Magnús).
