In Nazi German terminology, Volksdeutsche () were "people whose language and culture had German origins but who did not hold German citizenship". The term is the nominalised plural of volksdeutsch, with Volksdeutsche denoting a singular female, and Volksdeutsche(r), a singular male. The words Volk and völkisch conveyed the meanings of "folk". The Volksdeutsche (ethnic Germans at the time) shed their identity as Auslandsdeutsche (Germans abroad) and morphed into the Volksdeutsche in a process of self-radicalisation. This process gave the Nazi regime the nucleus around which the new Volksgemeinschaft was established across the German borders. Volksdeutsche were further divided into "racial" groups—minorities within a state minority—based on special cultural, social, and historic criteria elaborated by the Nazis. Origin of the term According to the historian Doris Bergen, Adolf Hitler coined the definition of Volksdeutsche which appeared in a 1938 memorandum of the German Reich Chancellery. That document defined Volksdeutsche as "people whose language and culture had German origins but who did not hold German citizenship". After 1945, the Nazi citizenship laws of 1935 () - and the associated regulations that referred to the National Socialist concepts of blood and race in connection with the concept of volksdeutsch - were rescinded in Germany. For Hitler and the other ethnic Germans of his time, the term "Volksdeutsche" also carried overtones of blood and race not captured in the common English translation "ethnic Germans". According to German estimates in the 1930s, about 30 million Volksdeutsche and Auslandsdeutsche (German citizens residing abroad) lived outside the Reich. A significant proportion of them were in Eastern Europe: Poland, Ukraine, the Baltic states, and Romania, Hungary and Slovakia, where many were located in villages along the Danube; and in Russia. The Nazi goal of expansion assigned the Volksdeutsche a special role in German plans, to bring them back to German citizenship and to elevate them to power over the native populations in those areas. The Nazis detailed such goals in Generalplan Ost. In some areas, such as in Poland, Nazi authorities compiled specific lists and registered people as ethnic Germans in the "Deutsche Volksliste". Historical background In the sixteenth century Vasili III invited small numbers of craftsmen, traders and professionals to settle in Russia from areas that would later become Germany so that Muscovy could exploit their skills. These settlers (many of whom intended to stay only temporarily) were generally confined to the German Quarter in Moscow (which
