Nazi Party
"Deutsche Gemeinschaft" was a branch of the Nazi Party founded in 1919, created for Germans with "Volksdeutsche" status. It is not to be confused with the post-war right-wing "", which was founded in 1949.
Nazism
The first party that attempted to combine nationalism and socialism was the (Austria-Hungary) German Workers' Party, which predominantly aimed to solve the conflict between the Austrian Germans and the Czechs in the multi-ethnic Austrian Empire, then part of Austria-Hungary. In 1896 the German politician Friedrich Naumann formed the National-Social Association which aimed to combine German nationalism and a non-Marxist form of socialism together; the attempt turned out to be futile and the idea of linking nationalism with socialism quickly became equated with antisemites, extreme German nationalists and the "Völkisch" movement in general.
