Christopher Columbus
When he was trying to make Spanish settlers happy, Columbus started the Encomienda system in Hispaniola.  Under this system, Columbus would give a piece of land in Hispaniola to an individual Spanish settler.  Sometimes, he would give away a whole native village.  Any natives that lived in that area had to work for that Spanish settler.  Natives had lived on this land for centuries. Columbus was giving their land away, and then forcing them to work on that land.
