The adoption of the fashions, mannerisms, and ideals of Western Europe by the Russian nobility was a gradual process rooted in the strict guidelines of Peter the Great and the educational reforms of Catherine the Great. While cultural westernization was mostly superficial and restricted to court, it coincided with the efforts of Russian autocrats to link Russia to Western Europe in more fundamental ways – socially, economically and politically. However, Russia's existing economic system, which lacked a sizable middle class and which relied heavily on forced labor, proved an insurmountable obstacle to the development of a free market economy. Furthermore, the lower classes (an overwhelming majority of the Russian population) lived virtually isolated from the upper classes and the imperial court. Thus, most of the nobility's “western” tendencies were largely aesthetic and confined to a tiny proportion of the populace.
