I am supposed to write a paper about Native American Indians. I can choose any tribe and then choose a specific topic (like religion or economic system or political organization) to write. I have been trying to find a topic for a while but can't find an interesting topic for a certain tribe. If you guys know about Native Americans and could recommend me a tribe and a topic that I can find enough information about, it would be highly appreciated.

And the paper is 5-7 pages, doubled spaced.

Thank you very much.
