The French Communist Party (French: Parti communiste français, PCF ; French pronunciation: [paʁ.ti.kɔ.my.nist.fʁɑ̃.'sɛ]) is a left-wing political party in France which advocates the principles of communism. Founded in 1920 by the majority faction of the socialist French Section of the Workers' International (SFIO), it participated in three governments. It was also once the largest French left-wing party in a number of national elections, from 1945 to 1960, before falling behind Socialist Party in the 1970s.
Although its electoral support has declined in recent decades, the PCF retains a strong influence in French politics, especially at the local level. In 2012, the PCF claimed 138,000 members including 70,000 who have paid their membership fees.This would make it the third largest party in France in terms of membership.
