Nazi legal theory divided all Germans into two categories, namely the "Volksgenossen" ("National Comrades") who belonged to the "Volksgemeinschaft" and the "Gemeinschaftsfremde" ("Community Aliens") who did not. In addition to the duties and responsibilities shared by those in the community, the National Comrades were expected to build and create a "Volksgeist" that would encompass the best aspects of the German people. As such, community aliens could not belong, since they were deemed an undermining element in the very foundations of the "Volksgemeinschaft".
