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 Communist Party of Germany (KPD) was the largest Communist Party in the world outside of the Soviet Union, until it was destroyed by the Nazis in 1933. In the 1920s and early 30s, Communists and Nazis often fought each other directly in street violence, with the Nazi paramilitary organizations being opposed by the Communist Red Front and Anti-Fascist Action. After the beginning of the Great Depression, both Communists and Nazis saw their share of the vote increase. However, while the Nazis were willing to form alliances with other parties of the right, the Communists refused to form an alliance with the Social Democratic Party of Germany, the largest party of the left. After the Nazis came to power, they quickly banned the Communist Party under the allegation that it was preparing for revolution and that it had caused the Reichstag fire. Four thousand KPD officials were arrested in February 1933, and by the end of the year 130,000 communists had been sent to concentration camps.
