On the Claim by Historian, Harold E. Driver, that Just as Many Indians Were Slain by Their Fellow Indians AFTER CONTACT WITH WHITES as Were Killed In Their Battles with These Whites

So yet one more nail in the coffin of the noble savages flourishing in perfect harmony with one another, in other words. Got it.

  More from Driver's book, "Indians of North America"

  "......the European settlers did not bring the first warfare to North America. Indian tribes had fought among themselves for thousands of years. They struggled constantly for the best hunting grounds and village sites, for revenge after the killing of a tribesman, and for personal glory......But not all tribes were equally warlike. Some, including the Iroquois and the Apache, fought almost all the time."
