We can say without any doubt, that the Russian Revolution of October 1917 not only changed Russia's government but also inspired a century of working-class radicalism, internationalism and colonial liberation around the world. Under the leadership of the Bolsheviks, an alliance of workers and peasants overthrew the Provisional Government that was established following the Tsar's abdication in February. One of their first moves was to quickly withdraw Russia from the carnage of World War One and went on to establish the world’s first socialist state – the Soviet Union or  U.S.S.R.
