Heimosodat

The Finnish term Heimosodat (singular heimosota) refers to a series of armed conflicts and private military expeditions in 1918–1922 into areas of the former Russian Empire that bordered on Finland and were inhabited in large part by other Finnic peoples.

The term has been translated into English as "Kindred Nations Wars", "Wars for kindred peoples", "Kinfolk wars", or "Kinship Wars," specifically referring to Finnic kinship. Finnish volunteers took part in these conflicts, either to assert Finnish control over areas inhabited by related Finnic peoples, or to help them gain independence from Soviet Russia. Many of the volunteers were inspired by the idea of "Greater Finland". Some of the conflicts were incursions from Finland, and some were local uprisings in which volunteers wanted either to help people fight for independence or to annex areas to Finland. According to Aapo Roselius, about 10,000 volunteers from Finland took part in the armed conflicts mentioned below.


 * Viena expedition (1918)
 * Murmansk Legion
 * Petsamo expeditions (1918 and 1920)
 * Estonian War of Independence (1918–1920)
 * Pohjan Pojat (lit. 'Sons of the North') and 1st Finnish Volunteer Corps helped Estonian troops.
 * Revolt of the Ingrian Finns (1918–1920)
 * Aunus expedition (1919)
 * Advance on Petrograd (1919)


 * East Karelian Uprising (1921–1922)

The phenomenon is closely linked to nationalism and irredentism, as Finland had just formally gained its national independence in 1917, and a part of the population felt that they had obligations to help other Finnic peoples to attain the same. Estonia, the closest and numerically largest "kindred nation", had gained its independence at the same time, but had fewer resources, fewer institutions ready to support its attained position, and more Bolshevik Russian troops within its borders. Other Finnic peoples were at a less organized level of cultural, economic and political capability. The Finnish Civil War had awakened strong nationalistic feelings in Finnish citizens and other Finnic peoples, and they sought tangible ways to put these feelings into action. For the two next decades, Finns participated at a relatively high rate in nationalistic activities (e.g. Karelianism and Finnicization of the country and its institutions). This development was related to the trauma and divisiveness of the Finnish Civil War. Many White sympathizers in the Civil War became radically nationalistic as a result of the war. The strenuous five-year period 1939–45 of total war — which also mostly unified the nation — reduced this enthusiasm.

Viena expedition
The Viena expedition was a military campaign conducted by Finnish forces against the local Bolsheviks and British troops in North Russia, who were there as part of the Allied intervention against Soviet power. The campaign took place in White Karelia and was part of Finland's efforts to establish a Greater Finland following their victory in the Finnish Civil War. The expedition involved two Finnish armed groups, the Northern and Southern groups.

Northern Group

The Northern Group was led by Kurt Martti Wallenius. Initially, it achieved some successes but faced strong resistance from the Finnish Red Guards. These challenges, coupled with military stalemates and internal mutinies within the Finnish forces, eventually forced the Northern Group to withdraw from White Karelia and retreat back into Finland.

Southern Group

Glossary

 * Sota : "War", in this context, a low-intensity one, consisting of actions such as border skirmishes, expeditions by volunteer corps, expulsion of remnant occupational forces or attempts to foment rebellion in the local populace.


 * Heimo : "Tribe" or "clan", but in this context, also the ethnic and language kinship between Baltic Finns; "kindred peoples". Somewhat comparable to the German concept of Völkisch.


 * Sukukansa : People who are linguistically and/or ethnically akin to one another; "suku" means "family" and "kansa" means "people" (singular).
