The Iroqois and Algonquins had a long running war. One of the highlights was when the Iroquois massacred the entire Erie tribe. Approximately 1,000 Eries were tied individually to trees and burned alive, all in one day, somewhere near the eastern shore of Lake Erie.
At one point the Iroquois were willing to travel hundreds of miles to the west to massacre a tribe in Illinois.
Ritual cannibalism was common among these tribes. Eating the heart of a brave enemy was believed to confer bravery on the diner. You don't want to know about the tortures they employed . . .
