I often view college students (and even professors) in some video dialog where they want to talk about the great evil where Europeans settling America.....did a something terrible, and owe the land back to 'THE' Indians.
There's a historical problem when you go and discuss 'THE' Indians....because they split off into not just dozens of tribes but literally hundreds of tribes (if you consider Canada, Mexico, the US, and Central America). At various times.....x-tribes had control of x-land, and later, a y-tribe came along to conquer that group, and then later, a z-tribe came along to conquer that group.
Does it sound somewhat like African tribal warfare? Yes, it's identical.
Does it sound somewhat like Asian tribal warfare? Yes, it's identical.
Does it sound like European tribal warfare? Yes, it's identical.
You can go over to the Creek Indians and find that they had various wars with other tribes, and killed a fair sum of non-Creek Indians over the past couple hundred years.
