In 997, Olaf founded his seat of government in [[Trondheim]], where he had first held a ''thing'' with the revolters against Haakon. It was a suitable site because the [[Nidelva|River Nid]] twisted itself before going into the fjord, creating a peninsula that could be easily defended against terrestrial attacks by only one short wall.

Both his Wendish and his Irish wife had brought Olaf wealth and good fortune, but, according to the Sagas, his last wife, [[Tyra of Denmark|Tyra]], was his undoing, for it was on an expedition undertaken in 1000 to wrest her lands from Burislav that he was waylaid off the island Svolder by the combined Swedish, Danish, and Wendish fleets, together with the ships of Earl Haakon's sons.<ref name="EB1911">{{EB1911|inline=y|wstitle=Olaf (kings of Norway)|display=Olaf ''s.v.''
