“I don’t think they “relocated”, I think their stuff “relocated”.”
American Indians in general were big slave raiders preying on each other.
Isn’t there a tribe near there that has blue eyes?
No, only some tribes were, not all by any means. Some were notorious like the traditional slavers of the Northwest who had been slaving long before whites came, or the newer ones like the Chickasaw, who when deerskins were becoming harder to obtain for trade, turned to preying on their brethren the Choctaw, capturing and selling Choctaws to white traders on the coast who shipped them to the Caribbean islands.
Slavery sprang up all over the world whenever there was warfare for territory or for women, and enough revulsion to killing captives to justify it... primitive cultures had no prisons and not enough resources to support and guard prisoners of war, so they had to choose between killing those who surrendered or selling most of them to protect themselves from their captives. That meant only keeping a few they thought they could adopt, or could control, like the very young … a few older prisoners might also be kept because they had some skill or use that made it worth the risk of keeping them, but the rest would have to be killed before white buyers were on the scene to create a market for them.
for savages living in the stone age, a “tenterhook” probably had the coveting allure that an iphone might have today.
