During World War II, the secret protocol in Molotov–Ribbentrop pact enabled the Winter War (1939–40), a Soviet attack on Finland. Finland and Nazi Germany were "co-belligerents" against Soviet Union during the Continuation War (1941–44), but a separate peace with Soviet Union led to the Finnish-German Lapland War (1944–45).
Finland recognised both the Federal Republic of Germany and the German Democratic Republic (West and East Germany) in 1972 and it established diplomatic relations with East Germany in July 1972 and with West Germany in January 1973.[4]
In July 2022, Germany fully approved Finland's application for NATO membership.[5]
