I believe it was late 1991 or 1992 that the National Geographic ran a series on Columbus. One of the stories covered the native tribes pre-columbus. Most of what has been said here is true. So many tribes many different situations: war, etc all the way to peace and developed forms of government. I suggest you check out NG,

National Geographic went touchie-feelie and made a sharp left turn in the seventies.
Nice propaganda but there are better neutral sources today.

Unless your interests happen to be environmental and political correctness.
