The "Gorbachev phenomenon" is seen as the product of complex developments during the last seventy years—developments that changed the Soviet Union from a primarily agrarian society into an urban, industrial one.

Moshe Lewin is Professor of History at the University of Pennsylvania and the author of several books on Soviet history.
