Moscow Armistice in the context of "Finland in World War II"

The Continuation War, also known as the Second Soviet–Finnish War, was a conflict fought by Finland and Nazi Germany against the Soviet Union during World War II. It began with a Finnish declaration of war on 25 June 1941 and ended on 19 September 1944 with the Moscow Armistice. The Soviet Union and Finland had previously fought the Winter War from 1939 to 1940, which ended with the Soviet failure to conquer Finland and the Moscow Peace Treaty. Numerous reasons have been proposed for the Finnish decision to invade, with regaining territory lost during the Winter War regarded as the most common. Other justifications for the conflict include Finnish President Risto Ryti's vision of a Greater Finland and Commander-in-Chief Carl Gustaf Emil Mannerheim's desire to annex East Karelia.

On 22 June 1941, the Axis invaded the Soviet Union. Three days later, the Soviet Union conducted an air raid on Finnish cities which prompted Finland to declare war and allow German troops in Finland to begin offensive warfare. By September 1941, Finland had regained its post–Winter War concessions to the Soviet Union in Karelia. The Finnish Army continued its offensive past the 1939 border during the invasion of East Karelia and halted it only around 30–32 km (19–20 mi) from the centre of Leningrad. It participated in besieging the city by cutting the northern supply routes and by digging in until 1944. In Lapland, joint German–Finnish forces failed to capture Murmansk or cut the Kirov (Murmansk) Railway. The Soviet Vyborg–Petrozavodsk offensive in June and August 1944 drove the Finns from most of the territories that they had gained during the war, but the Finnish Army halted the offensive in August 1944.

The Kymi Province (Finnish: Kymen lääni, Swedish: Kymmene län) was a province of Finland from 1945 to 1997.

The Kymi Province was the remainder of the territory from the Viipuri Province after the main part was left to Russia at the Moscow Armistice in 1944. By the Paris Peace Treaty in 1947, territories on the Karelian Isthmus and around of the Lake Ladoga were formally ceded to the Soviet Union.
