Norrland is a historical land of Sweden. To the west it represents the northern half of Sweden bounded to the south by Svealand and to the east it represents the northern half of Finland bounded to the south by Österland.
As the Swedish kingdom expanded north both on the western (Swedish) side and the eastern (Finnish) side of the Gulf of Bothnia the territories uncovered were organised into provinces. At the Treaty of Roskilde (1658) Norway ceded Jemtia and Herdalia to Sweden and which were incorporated as provinces. Upon the separation of Sweden and Finland in 1809 Norrland was split in two parts, leaving all of Ostrobothnia, and the eastern parts of Lapponia and Westrobothnia to the Grand Duchy of Finland, as a part of the Russian Empire.
