Rǫgnvaldr Óláfsson

Rǫgnvaldr Óláfsson was a mid-thirteenth-century King of Mann and the Isles who was assassinated after a reign of less than a month. As a son of Óláfr Guðrøðarson, King of Mann and the Isles, Rǫgnvaldr Óláfsson was a member of the Crovan dynasty. When his father died in 1237, the kingship was assumed by Haraldr Óláfsson. The latter was lost at sea late in 1248, and the following year Rǫgnvaldr Óláfsson succeeded him as king.
