Answer:
Tribal sovereignty is the power to govern themselves by creating, executing and evaluating their own laws and legislature.
Step-by-step explanation:
Tribal Sovereignty refers to the rights given to the Indian tribes to make their own rules, govern themselves, and also execute their own laws, without the involvement of the federal government. In governing themselves and within their own tribes, they were able to maintain their identity and traditions.
The act of allowing for tribal sovereignty also signifies that the US constitution recognizes these native tribes of their own identity. The act also sends a feeling of trust among the Indians, for in getting their own government, they also felt secure and at ease, like they fully belong.
Thus, the correct answer is the third option.
