title: History of socialism
context: After three years, the First World War, at first greeted with enthusiastic patriotism, produced an upsurge of radicalism in most of Europe and also as far afield as the United States  (see Socialism in the United States) and Australia. In the Russian revolution of February 1917, workers' councils (in Russian, soviets) had been formed, and Lenin and the Bolsheviks called for "All power to the Soviets". After the October 1917 Russian revolution, led by Lenin and Trotsky, consolidated power in the Soviets, Lenin declared "Long live the world socialist revolution!".[86] Briefly in Soviet Russia socialism was not just a vision of a future society, but a description of an existing one. The Soviet regime began to bring all the means of production (except agricultural production) under state control, and implemented a system of government through the workers' councils or soviets.
