"Politiken" was launched in 1916, first issue published on 27 April that year, by the left-wing of the Swedish Social Democratic Party. The left-wing was expelled from the Party in the summer of 1917, and the Social Democratic Left, under the leadership of Zeth Höglund and Ture Nerman, became the Communist Party of Sweden, strongly supporting the Russia October Revolution and the Bolsheviks. "Politiken" also published many texts by international communist leaders.
