 Lenin and his wife returned to Bern, before relocating to Zürich in February 1916.Lenin was angry that the German Social-Democratic Party was supporting the German war effort—a direct contravention of the Second International's Stuttgart resolution that socialist parties would oppose the conflict—and thus saw the Second International as defunct.He attended the Zimmerwald Conference in September 1915 and the Kienthal Conference in April 1916, urging socialists across the continent to convert the "imperialist war" into a continent-wide "civil war" with the proletariat pitted against the bourgeoisie and aristocracy.
