Finnish War

from 21 February 1808 to 17 September 1809

The Finnish War was fought between Russia and Sweden, after Russia, now allied with Napoleon following the Treaty of Tilsit, sought to pressure Sweden into joining the Continental System. Russian forces invaded Finland, then the eastern part of the Swedish realm, and the Swedish fortress of Sveaborg, near Helsinki, surrendered in 1808. In Sweden, King Gustav IV Adolf was deposed in a coup and replaced by his uncle, who became Charles XIII. By the Treaty of Fredrikshamn, Sweden ceded Finland to Russia, and Finland became the autonomous Grand Duchy of Finland within the Russian Empire under Alexander I. The loss ended centuries in which Finland had been part of the Swedish kingdom.
