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.
Nazi Germany
The official name of the state was "Deutsches Reich" from 1933 to 1943 and "Großdeutsches Reich" from 1943 to 1945, while common English terms are "Nazi Germany" and "Third Reich". The latter, adopted by Nazi propaganda as "Drittes Reich", was first used in a 1923 book by Arthur Moeller van den Bruck. The book counted the Holy Roman Empire (962–1806) as the first Reich and the German Empire (1871–1918) as the second.
