The 'Finnish Democratic Republic' (
Finnish: ''Suomen Kansanvaltainen Tasavalta'') was a short-lived
Soviet puppet regime in those minor parts of
Finland that were occupied by the
Soviet Union during the
Winter War. Its government was known under the name of the 'Terijoki Government'. The Soviet Union argued that it was the only rightful government for all of Finland that was capable of ending the Winter War and restoring peace.
It was established on
December 1,
1939, in the then-Finnish border town of
Terijoki (which is now
Zelenogorsk, part of the
Saint Petersburg recreation area in
Russia). During its lifespan
Otto Ville Kuusinen was chairman and
head of government.
On
March 12,
1940, it was merged with the
Karelian ASSR within the
Russian SFSR to form the
Karelo-Finnish SSR, a
Soviet republic in its own right.
