cargo cult, native religious movement found in Melanesia and New Guinea, holding that at the millennium the spirits of the dead will return and bring with them cargoes of modern goods for distribution among its adherents. The cult had its beginnings in the 19th cent. and received great impetus from World War II, when the Western armed forces littered the islands with surplus cargo. The cult aims to restore a past time and to regain the goodwill of ancestors who are being lured into giving cargo to the white foreigners, cargo originally intended for the native Melanesians. Cargo cults are revivalistic, in that the adherents expect the restoration of a golden age in which they will be reunited with their ancestors, and nativistic (see nativism nativism, in anthropology, social movement that proclaims the return to power of the natives of a colonized area and the resurgence of native culture, along with the decline of the colonizers.

However, as the cargo is composed principally of European goods, and native goods and rituals are abandoned, both the nativistic and revivalistic aspects of cargo cults are qualified by a strong motive toward acculturation acculturation, culture changes resulting from contact among various societies over time. Contact may have distinct results, such as the borrowing of certain traits by one culture from another, or the relative fusion of separate cultures.

cargo cult

Any religious movement based on the observation by local residents of the delivery of supplies by ship and aircraft to colonial officials. Cargo cults were observed chiefly in Melanesia in the late 19th and early 20th centuries. They were characterized by the expectation of a new age of blessing and prosperity to be initiated by the arrival of a special “cargo” of goods from supernatural sources. Such beliefs may have expressed traditional millennial ideas, often revived by the teaching of Christian missions.
