The indigenous peoples of the Pacific Northwest were likely the most affluent Native Americans. Many distinct cultural groups and political entities developed there, but they all shared certain beliefs, traditions, and practices, such as the centrality of salmon as a resource and spiritual symbol. Permanent villages began to develop in this region as early as 1,000 BCE, and these communities celebrated by the gift-giving feast of the potlatch. These gatherings were usually organized to commemorate special events such as the raising of a Totem pole or the celebration of a new chief.
