When reading Ekaterina Pravilova’s original, fascinating and meticulously researched “The Ruble” it is a good idea to keep in mind its subtitle: “A Political History.” For Ms. Pravilova’s multi-layered account of the evolution of the paper ruble from its inception in the mid-18th century until the post-revolutionary reforms in the early 1920s goes beyond the merely monetary. “The biography of the ruble,” explains Ms. Pravilova, “is a history of the Russian state, written in the language of money.” Regardless of the type of political system in place, she writes, “money does not simply reflect an existing (or imagined) social and political order but creates it; it is not a consequence or an attribute but an integral and constitutive part of any regime.” Ms. Pravilova, a professor of history at Princeton, shows that the ruble has been, above all, a symbol and an instrument of centralized, autocratic and imperial power.
