Carélie orientale
The Viena expedition (, ) was a military expedition in March 1918 by Finnish volunteer forces to annex White Karelia ("Vienan Karjala") from Bolshevist Russia. It was one of the many "kinship wars" ("Heimosodat") fought near the newly independent Finland during the Russian Civil War. The Russian East Karelia was never a part of the Swedish Empire or the Grand Duchy of Finland and it was at the time mostly inhabited by Karelians. However, many advocates of a Greater Finland considered these Karelians a "kindred" Finnish nation and supported the annexation of Russian East Karelia to Finland.
