Bow and Arrow Wars in Western and Northwestern Alaska?  Conflicts between Athabaskans and Inupiat & Yupik. Chukots raiding Inupiat and Yupik for loot and slaves and vice versa. That doesn't even touch on the slavery and warfare along the Pacific coastline. Of course when the Russians showed up shooting people indiscriminately, there was a move towards getting along, or at least not murdering each other as often...........
