An attempt of comparative outline of the development in Finland and Czechoslovakia in the years 1945-48 is made in the study. There were a number of substantial differences in the position of the two countries due to their different historical development and to the incomparable geopolitical situation. On the one hand, the Soviet-controlled Allied Control Commission interfered in the events taking place of the defeated Finland, while most of the Finnish population, on the other hand, regarded 'the Russians' as the greatest threat to their country, which also found its reflection in its attitude to the local Communists. Although the Finnish Communist Party tried hard to strengthen its position through the wider Democratic League of the Finnish People, the political base of the Party - unlike that of the Communist Party of Czechoslovakia - remained limited. A great difference can also be observed in the policy of the Finnish Social Democratic Party, which failed to closely cooperate with the Communists. Nevertheless, the Finnish democratic representation was aware of the USSR's supremacy in the region, and was therefore ready to accept the Defense Alliance Agreement proposed by the Soviets. Its signing on April 5th, 1948 provided a framework for the follow-up 'finlandization' policy that made it possible for the Finns to retain their internal democratic order.
