This authoritative study examines Russia's four key succession crises: after Stalin's death, throughout Khrushchev's primacy, during the implosion of the USSR, and with Putin's ascent to power. The distinguished authors argue that the common denominator has been the absence of a transparent, non-arbitrary, and lawful mechanism for the transfer of political power. Consequently, contenders for leadership have engaged in vicious power struggles followed by pseudo-legitimation of the victor. As Moscow reemerges as a major international actor, its unpredictability domestically triggers after shocks well beyond Russia's borders. Drawing on newly available primary sources, this book provides essential insights for practitioners and students of policy alike.
