Communist countries are notably history-minded. Since they see mankind as advancing toward socialism and communism as part of a law-determined historical process, they base their legitimacy in large part on historical antecedents. East Germany, being faced with the opposing claims of West Germany, has been particularly concerned with establishing its historical legitimacy. The German Democratic Republic (GDR) traces its roots back into a distant past, along a road on which medieval peasant risings, socioreligious upheavals, Reformation and Peasants' War, the War of Liberation against Napoleon I, and the revolutions of 1848 and 1918 stand as significant milestones. Perhaps no Communist leadership ever did its homework in history more thoroughly prior to its assumption of power than did the East German leaders. From the mid-1930s on, in their Moscow exile, they devoted considerable attention to the exploration of historical questions from the Marxist perspective; later, Marxist historians and Communist party officials began drawing up plans for historical study programs, textbooks, and monographs in preparation for the day when they would be able to take over power in Germany. They knew it would be important to prepare the way “historically,” too, for the transformation of Germany from a capitalist into a socialist society.
