Tatkreis
The Tatkreis, or "Action Circle", was a Völkisch movement which existed during the era of the Weimar Republic. They followed the beliefs of most Völkisch movements but claimed the current republic "corrupt and sterile beyond repair" and called for "freedom and rebirth" in Germany. The Tatkreis used a combination of nationalism and 'revolutionary' conservatism to generate passion within their ranks in a fashion that pre-dated Nazism and was no doubt an influence.
The Tatkreis called for an end to capitalism and promoted a neomercantilist ideology, a system which encourages exports and discourages imports and called for German self-sufficiency. This idea was easily received by the citizens of Germany, who lived in a time of depression after World War I and leading up to World War II. The middle-class craftsmen and shopkeepers were a majority in Germany and thus a key demographic.
At the end of the 1920s the Tatkreis was formed around the publication Die Tat ("Action"). Die Tat, edited by Hans Zehrer, produced a circulation of over 25,000 in 1933. After the rise to power of the Nazi Party the Tatkreis was dissolved, as were other political parties under Nazi rule. Even before this, the way the Nazi Party truly undermined the Tatkreis was by drawing from their membership, as both parties targeted the same types of followers.
