Konstantin Dmitrievich Kavelin has long been regarded as both a leader and archetype of nineteenth-century Russian liberalism. It is not clear, however, what “liberal” and “liberalism” mean with reference to nineteenth-century Russia. Russian liberals of the early twentieth century, seeking to create a tradition for their movement, put the most diverse figures from the past in the liberal pantheon. Soviet historians, with somewhat more justice but the same kind of zeal, have sharply demarcated mid-century radicals, with, whom they sympathize, from the liberals. American historians of Russia tend to characterize as “liberal” almost anyone who tried to achieve social and political improvements by nonrevolutionary means. And almost all historians have resorted to the tautology whereby “liberalism” denotes the activities and doctrines of those public figures whom we know to be “liberals.”
