The paper money of the Soviet Republic supported the Soviet Government in its most difficult moments, when there was no possibility of paying for the civil war out of direct tax receipts. Glory to the printing press! To be sure, its days are numbered now but it has accomplished three-quarters of the task. In the archives of the great proletarian revolution, alongside the modern guns, rifles, and machine guns which mowed down the enemies of the proletariat, an honorary place will be occupied by that machine gun of the People’s Commissariat of Finance which attacked the bourgeois regime in its rear – its monetary system – by converting the bourgeois economic law of money circulation into a means of destruction of that same regime and into a source of financing the revolution.
– Bolshevik economist Evgeny A. Preobrazhensky, in his booklet entitled Paper Money during the Proletarian Dictatorship, published in 1920.
