▪ tradeexchange system among the people of the Trobriand Islands of southeast Melanesia, in which permanent contractual partners trade traditional valuables following an established ceremonial pattern and trade route. In this system, described by the Polish-born British anthropologist Bronisław Malinowski (Malinowski, Bronisław), only two kinds of articles, traveling in opposite directions around a rough geographic ring several hundred miles in circumference, were exchanged. These were red shell necklaces and white shell bracelets, which were not producers' capital, being neither consumable nor media of exchange outside the ceremonial system. Kula objects, which sometimes had names and histories attached, were not owned in order to be used but rather to acquire prestige and rank.Every detail of the transaction was regulated by traditional rules and conventions, and some acts were accompanied by rituals and ceremonies. A limited number of men could take part in the kula, each man keeping an article for a relatively short period before passing it on to one of his partners from whom he received the opposite item in exchange. The partnerships between men, involving mutual duties and obligations, were permanent and lifelong. Thus the network of relationships around the kula served to link many tribes by providing allies and communication of material and nonmaterial cultural elements to distant areas.
