Final answer:
The purpose of ceremonies to the 5 southeastern tribes was to maintain their spiritual relationship with nature, acknowledge their social hierarchies, and reinforce alliances and trade within their complex religious and socio-political system.
Step-by-step explanation:
The purpose of the ceremony to the 5 southeastern tribes, which include the Cherokee, Chickasaw, or Seminole among others, was deeply spiritual and socio-political in nature. These ceremonies were integral to the Southeastern Ceremonial Complex, which was the religion of the Mississippians. Their ceremonial practices involved reaffirmation of their connection to nature and the universe, acknowledgement of their social hierarchies, and the strengthening of alliances through political and trade networks.
Key symbols such as the snake, a cross in circle motif, and Birdman emphasized the relationship between cosmology and the socio-political structure of the tribes. Only the elite possessed sacred objects associated with these symbols, which were believed to hold great power. These ceremonies also included practices that aimed at dealing with adversities such as diseases by spiritual means.
In these tribal societies, ceremonies established a spiritual relationship with nature, instilling a sense of stewardship over the natural resources that sustained their people. Some native practices involved ceremonial actions like the first hunt or the first salmon catch, which were methods of acknowledging the responsibilty they had towards the environment.
