The Francs-tireurs et partisans – main-d'œuvre immigrée (FTP-MOI) were a sub-group of the Francs-tireurs et partisans (FTP) organization, a component of the French Resistance. A wing composed mostly of foreigners, the MOI maintained an armed force to oppose the German occupation of France during World War II. The Main-d'œuvre immigrée was the "Immigrant Movement" of the FTP.
The FTP-MOI groups were organized in the Paris region in 1941, at the same time as the Francs-tireurs et partisans. Their ranks were filled with foreign communists living in France who were not part of the French Communist Party. Although integrated with the FTP, these groups depended directly on Jacques Duclos, who passed on orders from the Communist International (Comintern). Members also included other immigrants, especially many young Hungarian writers, artists and intellectuals. Among them were the painter Sándor Józsa; sculptor István Hajdú (Etienne Hajdu); journalists László Kőrösi and Imre Gyomra; photographers Andras (André) Steiner, Lucien Hervé, and Ervin Marton; and printer Ladislas Mandel.
The FTP-MOI were among the most active and determined of the resistance groups; particularly because they were foreigners and mostly Jews, they were under the direct watch of the Vichy regime and the Germans. Without maintaining strict secrecy, they risked internment, deportation and death. Because they depended directly on the Comintern, with Duclos as their intermediary, they were often on the front line when the order to fight came from Moscow. The various French groups were more attentive to the French national political climate.
