why do you think certain indians scalped their enemies?

White folk wanting the land cleared of Native Americans would often hire bounty hunters to clear the land. As proof of their working it's thought they started collecting the scalps of those they killed.
The Native Americans retaliated by doing the same.

They just copied what the white folks did. Somebody put a bounty on Indian scalps.

They didn't like being kicked off their own land?

To get a "HEAD" in the game XD lmfao but nah they did it to syoblize a kill it was a trophy
