Finland - Historical Flags (1920-1978)

Editorial Note: The shade of blue differs from that of the current flag. although the proportions and other graphical information is the same

White flag with blue cross and the Finnish coat of arms in the middle of the cross. Because Finland decided to be a republic instead of a monarchy, the government thought that the crown should be removed. The shield became almost a square. Lion's armoured arm and the blades of the weapons are coloured light grey but the roses are white. The shade of the blue became darker.

Adopted: 1944
Abolished: 1946

Marshall of Finland, Baron Carl Gustaf Emil Mannerheim used this flag to symbolize his position as the High Commander of the army and the President of the Republic. When Juho Kusti Paasikivi was elected president by the parliament after the war, he re-adopted the former version of the flag.

I don't know the exact dates when this flag was adopted and abolished, but because C. G. E. Mannerheim was president from 4 August 1944 to 9 March 1946 these are quite good guesses.

The Karelian-Finnish Soviet Socialist Republic was established 31 March 1940 and combined the territory of the former Karelian ASSR with areas taken from Finland in the Winter War.

At the beginning of the Winter War (Nov./Dec. 1939) Kuusinen (leader of Finnish communist emigrants in the USSR) formed a communist government in Terijoki near the border with the USSR. This was (off course) recognized by the USSR as the legal Finnish government, although later the peace-treaty was signed with the government in Helsinki.
