Book excerpt: This dissertation describes and analyzes the financial boom that made Russia the largest net international debtor in the world by 1914, as well as the Bolshevik default of 1918 -- one of the biggest in international financial history. For the Bolsheviks the default was a highly significant attack on "finance capital." Yet few historians have paid much attention to the financial history of the Russian Revolution. This study focuses in particular on the decision-making of the small but influential group of financiers and government officials who acted as the "gatekeepers" of international finance, channeling international capital to Russia in the late nineteenth and early twentieth centuries.
