The "Peaceful" Indian myth is relatively new and its amazing how widespread and accepted it has become. Absolutely brutal people. The only tribes with any sense (if you could call it that) were the ones being led by 1/4 and 1/8, 1/16 and 1/32 Indians such as William Weatherford of The Creeks (Muscogee) who was only 1/8th Indian and was bested by the great Andrew Jackson in the Creek War.
Many other tribes were led by Multi-racial chiefs some with 1/16 to 1/32 heritage. Another being Alexander McGillivray, who created an alliance between the Creek and the British during the American Revolution and was commissioned as a British Colonel and later commissioned as a Brigadier General for the United States after the war which allowed him to amass three plantations and 60 slaves.
