Potlatch

A potlatch is a gift-giving feast practiced by Indigenous peoples of the Pacific Northwest Coast of Canada and the United States,[1] among whom it is traditionally the primary governmental institution, legislative body, and economic system... A potlatch involves giving away or destroying wealth or valuable items in order to demonstrate a leader's wealth and power. Potlatches are also focused on the reaffirmation of family, clan, and international connections, and the human connection with the supernatural world. Potlatch also serves as a strict resource management regime, where coastal peoples discuss, negotiate, and affirm rights to and uses of specific territories and resources. https://en.wikipedia.org/wiki/Potlatch
