Communist Party of Switzerland

[3] The party drew most of its support from urban areas in German-speaking Switzerland, most notably the cities of Basel, Schaffhausen and Zürich.

[1] A major turning point occurred in 1930, when the expulsion of Walther Bringolf led to the split of nearly the entire Schaffhausen section into the Communist Party Opposition, which merged into the Social Democrats five years later.

[1] The number of party members and voters decreased progressively, though the adoption of popular front tactics in 1935 led to a slight increase in membership.

[1] Nevertheless, anti-communist laws adopted by a number of cantons, as well as party policies such as abandoning anti-fascism (following the Molotov–Ribbentrop Pact) and supporting the Soviet invasion of Finland led to a decline in popularity.

[1] During the Spanish Civil War, the party contributed to the International Brigades by assisting the mobilization of volunteers from Austria and other countries.
