A Potlatch can best be described as

a traditional ceremonial and social event practiced by Indigenous peoples of the Pacific Northwest Coast, including the Haida, Nuu-chah-nulth, Kwakwaka'wakw, Nuxalk, Tlingit, Makah, and Coast Salish. It involves the giving away or destruction of wealth as a way to demonstrate prestige, social status, and to build alliances within the community. Potlatches often include feasting, dancing, gift-giving, and other cultural performances.
