Torf-Einarr

Einarr Rognvaldarson (fl. early 890s–c. 910), often referred to by his bynameTorf-Einarr (sometimes anglicised as Turf-Einar), was one of the Norseearls of Orkney. The son of the Norse jarlRognvald Eysteinsson and a concubine, his rise to power is related in sagas which apparently draw on verses of Einarr's own composition for inspiration. After battling for control of the Northern Isles of Scotland and a struggle with Norwegian royalty, Einarr founded a dynasty which retained control of the islands for centuries after his death.

He is portrayed as a successful warrior and has various characteristics in common with the Norse god Odin but his is not in doubt. The reasons for his nickname of "Turf" are not certain.
