Why did many Europeans choose to enslave Native Americans instead of capturing and selling them?
It was what the king ordered the conquistadors to do in the new world.
It was the best way to keep an eye on the natives and make sure they weren't escaping.
The Europeans chose to enslave, rather than capture and sell, the Native Americans because the natives could be used to help them hunt and gather enough food for the winter.
It was easier, took less time, and allowed for quicker expansion of the territory.
