A cargo cult is a type of religious practice that may appear in tribal societies in the wake of interaction with technologically advanced, non-native cultures. The cults are focused on obtaining the material wealth of the advanced culture through magical thinking, religious rituals and practices, believing that the wealth was intended for them by their deities and ancestors. Following contact with people from more technically advanced societies through exploration, colonization, missionary efforts, and international warfare, cargo cults were initially documented in New Guinea and other Micronesian and Melanesian countries in the southwest Pacific Ocean.
Members, leaders, and prophets of cargo cults maintain that the manufactured goods ("cargo") of the non-native culture have been created by spiritual means, such as through their deities and ancestors, and are intended for the local indigenous people, but that, unfairly, the foreigners have gained control of these objects through attraction of these material goods to themselves by malice or mistake[citation needed]. Cargo cults thus focus on efforts to overcome what they perceive as the undue influence of the others attracting the goods, by conducting rituals imitating behavior they have observed among the holders of the desired wealth and presuming that their deities and ancestors will, at last, recognize their own people and send the cargo to them instead. Thus, a characteristic feature of cargo cults is the belief that spiritual agents will, at some future time, give much valuable cargo and desirable manufactured products to the cult members[citation needed].
