The beginnings of the province of Uusimaa lie in the
Swedish governance reforms of 1634. At that time, new counties were established also in the territories of Finland. The five counties established in Finland were the counties of Uusimaa and Häme, the counties of
Turku and
Pori, the counties of
Viipuri and
Savonlinna, the province of
Ostrobothnia and the county of
Käkisalmi. == Maps ==
