Studying Russian history from the West European perspective, one also becomes conscious of the effect that the absence of feudalism had on Russia. Feudalism had created in the West networks of economic and political institutions that served the central state, once it replaced the feudal system, as a source of social support and relative stability. Russia knew no feudalism in the traditional sense of the word, since, after the emergence of the Muscovite monarchy in the fifteenth and sixteenth centuries, all landowners were tenants-in-chief of the Crown, and subinfeudation was unknown. As a result, all power was concentrated in the Crown.
