History
Oulu County (Oulun lääni, Swedish: Swedish: Uleåborgs län) was first created in 1642 from Korsholm castle fief or castle county (Korsholman linnalääni, Swedish: Korsholms slottslän) as part of Axel Oxenstierna's 1634 Instrument of Government. In 1648 Oulu County was combined with Vaasa County to create Ostrobothnia County (Pohjanmaan lääni, Swedish:Österbottens län). In 1775 the county was divided back into Oulu and Vaasa counties. In 1938 the northern part of the county was separated to form Lappi County (Lapin lääni, Swedish: Lapplands län). In 2010 it was replaced by the Northern Finland Regional Administrative Office (Pohjois-Suomen aluehallintovirasto) as part of the Regional Administrative Agency (Aluehallintovirasto, Swedish: Regionförvaltningsverk)
