Between 20 January and 10 May 1942, the Partisans took control of Foča and the surrounding area, proclaiming the so-called Republic of Foča.
The Partisans established a postal service primarily for patriotic and promotional purposes rather than addressing practical postal needs. They used old Yugoslav stamps overprinted by the Ustasha with its coat of arms and the inscription "NEZAVISNA DRŽAVA HRVATSKA" ("INDEPENDENT STATE OF CROATIA"). These stamps were marked with a rubber cachet featuring a five-pointed star and the inscriptions "SMRT FAŠIZMU - SLOBODA NARODU" ("DEATH TO FASCISM - FREEDOM TO THE PEOPLE") and "Partizanska POŠTA" ("Partisan POST").
This is an interesting excerpt from Vladimir Dedijer's diary. It features two affixed stamps (Mi. 12 and 41), overprinted with a five-pointed star and cancelled with the "Foča 1.V.42" postmark, along with the mentioned inscriptions using provisional rubber cachets.
The 1942 Foča Partisan provisional issue includes two NDH stationery items: one with Mi. 12 and the other with Mi. P1, both bearing provisional rubber cachet overprints. Notably, the five-pointed star was deliberately overprinted to obscure the Ustasha symbols.
