This first volume of the Cambridge History of Russia covers the period from early ('Kievan') Rus' to the start of Peter the Great's reign in 1689. It surveys the development of Russia through the Mongol invasions to the expansion of the Muscovite state in the sixteenth and seventeenth centuries and deals with political, social, economic and cultural issues under the Riurikid and early Romanov rulers. The volume is organised on a primarily chronological basis, but a number of general themes are also addressed, including the bases of political legitimacy; law and society; the interactions of Russians and non-Russians; and the relationship of the state with the Orthodox Church. The international team of authors incorporates the latest Russian and Western scholarship and offers an authoritative new account of the formative 'pre-Petrine' period of Russian history, before the process of Europeanisation had made a significant impact on society and culture.
