History
After the Ice Age the land was left as a mosaic of lakes and ridges, and it was settled by Finnic hunters and then by slash-and-burn farmers from Savo and Karelia, who pushed north and west through the forests from the Middle Ages. Karelia faced east: Orthodox missionaries and Novgorod's traders reached it early, and the Treaty of Nöteborg of 1323 drew a border between Swedish and Novgorodian spheres that shaped its religion for centuries.
Sweden fortified the frontier. Olavinlinna was begun at Savonlinna in 1475 to defend Savo against Russia, and Kuopio and Joensuu grew later as market towns. The border moved west and east in repeated wars, and much of Savo and Karelia changed hands between Sweden and Russia in the 18th century before the whole region came under the Grand Duchy of Finland in 1809.
Industry arrived in Tampere, where the Scottish engineer James Finlayson founded a cotton mill on the Tammerkoski rapids in 1820; the city became Finland's leading manufacturing centre, and in 1918 it saw the largest military operation of the civil war, won by the Whites. Jyväskylä became a centre of Finnish-language education, opening the first Finnish-language teacher-training college in 1863. After the Second World War, North Karelia and Savo absorbed many of the evacuees from territory ceded to the USSR, and the region later shifted from farming and forestry towards universities, services and technology.
