King Eric Edmundson of Sweden ruled over Finland, Carelia, Esthonia, Courland and "wide over all Austria." These countries belonged to Sweden until King Olof Skoetkonung "let all his scatlands get away from him." The chronicler Rimbert says that Courland, by which he means the Baltic provinces, in 850 belonged to Sweden. Shortly after this date fall, according to Nestor, those of the first Swedish contact with interior Russia (859) and of the founding of the Russian empire by Rurik (862). The Swedish dominion in the Baltic provinces, as well as the early Russian empire, must consequently have held a position similar to the one of Normandie to France and England.
