Force PubliqueThe Force Publique (fɔʁs pyblik, "Public Force"; Openbare Weermacht) was a gendarmerie and military force in what is now the Democratic Republic of the Congo from 1885 (when the territory was known as the Congo Free State), through the period of Belgian colonial rule (Belgian Congo – 1908 to 1960). The FP was retitled as the Congolese National Army or ANC in July 1960 after independence.
