Finally in the year 1809, the treaty of Hamina made Sweden hand over Finland to Russia. Finland became Grand Duchy of Finland under the Russian control. The Finland Russia collaboration in almost all administrative matters was carried out all throughout the 19th century. But the tension began to emerge between the two countries from the 20th century, when the Russian government tried to involve Finnish armed forces into the Russian army. This angered the Finnish nationals and they broke out into a revolt.
With the beginning of the First World War, the situation deteriorated tremendously. Finland turned to Germany for help and Russia became one of its biggest enemies. The Russian Revolution of 1917, created a new element in the form of rightist and leftist parties. Finland gained complete independence from the Russian rule on 6th December, 1917.
