Southern and mid-Troms was a petty kingdom in the Viking Age, and considered part of Hålogaland. Ottar from Hålogaland met King Alfred the Great around 890. The Viking leader Tore Hund had his seat at Bjarkøy. According to the sagas, Tore Hund speared King Olav Haraldsson at the Battle of Stiklestad. He also traded and fought in Bjarmaland, today the area of Arkhangelsk in northern Russia . Trondenes (today's Harstad) was also a central Viking power centre, and seems to have been a gathering place.
