St. Petersburg was devastated by Lenin's Red Terror[18] then by Stalin's Great Purge[19] in addition to crime and vandalism in the series of revolutions and wars. Between 1917 and 1930s, about two million people fled the city, including hundreds of thousands of educated intellectuals and aristocracy, who emigrated to Europe and America. At the same time many political, social and paramilitary groups had followed the communist government in their move to Moscow, as the benefits of capital status had left the city.
