The history of German research and writing about migration has been heavily influenced by politics. The assumptions and methods of successive generations of migration researchers demonstrate the interplay of social science and politics across very different political regimes. Soon after serious research began in the late nineteenth century, migration researchers divided into two camps. Urban statisticians with liberal political ideas used city migration registration data to analyze the circulatory movement of migrants within Germany. Conservative writers used census data to argue that migration was essentially movement from countryside to city, and was politically and morally injurious to the German people. These two sides hardened after World War I, as the conservative side increasingly incorporated racist ideas into their critique of migration. This debate continued even after the Nazis took power in 1933 with the competing publications of Rudolf Heberle and Wilhelm Brepohl. Heberle was forced to leave Germany and Brepohl became the Nazis’ favorite analyst of migration. After 1945, Brepohl retained his standing as a leading migration researcher in the German Federal Republic. The dominance of this conservative interpretation of migration continued into the 1970s. In recent decades, the writings of the liberal statisticians from the late nineteenth and early twentieth centuries have been rediscovered, and German migration research has shifted again toward a more empirically based understanding of migration.

Demographic research is rapidly rewriting the history of the preindustrial European population. Numerous recent local studies contradict the common stereotype of geographical stability; European communities before 1800 housed highly mobile populations. Much of this new research concerns England and France, but significant migratory movement has also been found in early modern Sweden, Scotland, and Japan. This paper surveys the evidence on mobility in Germany since the later Middle Ages, and places it within a broad socioeconomic context.

The rapid expansion of historical demography as a discipline has meant a growing number of studies of past migration (excellent examples are Tugault, 1973; Chatelain, 1976; Piore, 1979), although migration still receives considerably less attention than does fertility or mortality. The study of industrializing cities during the nineteenth century has focused interest on those patterns of migration that caused rapid urban population growth (Anderson, 1971; Anderson, 1980; Crew, 1979; Thernstrom, 1970). Most of these recent studies of internal migration are based on localized information over relatively short periods of time. They provide us with demographic data of unprecedented precision, but the local nature of such studies accentuates their dependence on currently accepted generalizations as guides in the search for and interpretation of evidence.
