When it was originally published in 1987, this book provided the first comprehensive analysis of the ways in which changes in the international environment affected both the domestic politics, economies and the foreign policies of communist countries. Ronald Linden's comparative study examines the impact of such factors as détente, East-West trade, and fluctuations in the international capitalist economy on Romania and the former Yugoslavia to develop a broader theory of the ways in which Eastern European states adapted to external changes. The book will be of interest to Soviet and East European historians and to scholars of international relations, comparative politics and political economy.
