Arvo "Poika" Tuominen (1894-1981) was a FinnishCommunist revolutionary and later a social democratic journalist and politician. Tuominen was given his nickname Poika in 1920 because of his boyish looks—poika means "boy" in Finnish. Tuominen was born in 1894 in Kuotila near Hämeenkyrö to the family of a rural carpenter. In 1912 he moved to Tampere to become a carpenter's apprentice and soon joined the Social Democratic Party of Finland. During the Finnish Civil War in early 1918, Tuominen sided with the Finnish Red Guards and edited Kansan lehti, a radical social democratic newspaper in Tampere. After the Red Guards were defeated in May 1918, Tuominen and several other radical social democratic leaders fled to Russia, where they split from the mainstream of Finnish Social Democratic Party and founded the Communist Party of Finland in Petrograd in August-September 1918.
