Source-derived summary

The Karelo-Finnish Soviet Socialist Republic (Karelo-Finnish SSR), also called Karelo-Finland, Finno-Karelia and Soviet Karelia or simply known as Karelia, was a republic of the Soviet Union. It existed from 31 March 1940 until it was made part of the Russian SFSR on 16 July 1956 as the Karelian Autonomous Soviet Socialist Republic. The latter became the Republic of Karelia, a federal subject of Russia, on 13 November 1991.

History

The Karelo-Finnish Soviet Socialist Republic was established by the Soviet government on 31 March 1940 by merging the KASSR with the Finnish Democratic Republic. The latter was created in territory ceded by Finland in the Winter War by the Moscow Peace Treaty, namely the Karelian Isthmus and Ladoga Karelia, including the cities of Viipuri and Sortavala.

Virtually the entire Karelian population of the ceded areas, about 422,000 people, was evacuated to Finland, and the territories were settled by peoples from other parts of the Soviet Union.

Creating a new Republic of the Union for an ethnic group that was not large in absolute terms, nor constituted anything close to a majority in its territory, nor had been a separate independent nation before its incorporation into the USSR, was unprecedented in the history of the USSR. Some later historians believe that the elevation of Soviet Karelia from an Autonomous Soviet Socialist Republic (within the RSFSR) to an SSR was a political move as a "convenient means for facilitating the possible incorporation of additional Finnish territory" (or, possibly, the whole of Finland) into the USSR.

In 1941, during the Continuation War, Finland retook the territory that it had lost in 1940 after the Winter War and occupied most of the Karelian lands that had been within the USSR before 1940, including the capital Petrozavodsk (Petroskoi). In 1944, the Soviet Union recaptured the area. Soviet sovereignty was recognized by Finland in the Moscow Armistice and Paris Peace Treaty. The Finnish Karelians were evacuated to Finland again.

Editorial summary

This brief starts where responsible research should: with the source description of “Karelo-Finnish Soviet Socialist Republic” as union republic of the Soviet Union. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1940, 1956, 1991, 1941—that can be checked directly. The linked authority record independently contributes the date 1940-03-31. The account is most persuasive where Karelo-Finnish, Soviet and Socialist can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as union republic of the Soviet Union. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q186888. VIAF identifies the subject as 124341155. The Library of Congress control number is n81022403. Authority coordinates are 61.783, 34.350. 2 of 5 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1940, 1956, 1991 and 1941.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
