Kuinka kauan Suomen sisällissota jatkui?
The Finnish Civil War was a conflict from 27 January to 15 May 1918 for the leadership and control of Finland during the country's transition from a Grand Duchy of the Russian Empire to an independent state. The clashes took place in the context of the national, political, and social turmoil caused by World War I. The civil war was fought between the "Reds", led by a section of the Social Democratic Party, and the "Whites", controlled by the conservative-based Senate. The paramilitary Red Guards, were largely made up of industrial and agrarian workers and controlled the cities and industrial centres of southern Finland. The paramilitary White Guards consisted of farmers, along with middle-class and upper-class social strata, and controlled rural central and northern Finland.
