Finland during World War II encompasses three major conflicts. The first two of these – the defensive Winter War in 1939–1940, and the Continuation War alongside the Axis Powers in 1941–1944 – were waged against the Soviet Union. The third one, the Lapland War in 1944–1945, followed the signing of an armistice agreement with the Allied Powers, which stipulated expulsion of German forces from Finnish territory.
By the end of hostilities, Finland managed to defend its independence, but had to cede nearly 10% of its territory, including its second largest city, Viipuri, and pay out a large amount of war reparations to the Soviet Union. As a result of this territorial loss, many Finnish Karelians fled or were evacuated from their homes, relocating to areas that remained within the borders of Finland.
