TRUE.
Communism appeared on the political scene of France in 1920 thanks to the French Communist Party (PCF) and began strenghtening towards the end of World War II. But the party that brought Communism to the French Government was the Popular Front, an anti-fascist alliance that combined the PCF, the socialist French Section of the Workers' International (SFIO) and the Radical Party, by winning the 1936 elections and gaining 386 seats as a whole (72 of them were for the PCF).
