Finland's foreign politics before this deal had been varied: independence from Imperial Russia with support of Imperial Germany in 1917; participation in the Russian Civil War (without official declaration of war) alongside the Triple Entente 1918–1920; a non-ratified alliance with Poland in 1922; association with the neutralist and democratic Scandinavian countries in the 1930s ended by the Winter War (1939) which Finland lost against the Soviet Union; and finally in 1940, a rapprochement with Nazi Germany, the only power able and willing to help Finland against the expansionist Soviet Union, which led to Finland's re-entry into the Second World War in 1941.
