The history of slavery in Colorado began centuries before Colorado achieved statehood when Spanish colonists of Santa Fe de Nuevo México (1598–1848) enslaved Native Americans, called Genízaros. Southern Colorado was part of the Spanish territory until 1848. Comanche and Utes raided villages of other indigenous people and enslaved them. There were some instances of slaves in early 19th century, such as the Green family of Bent's Fort. Former enslaved men and women settled in Colorado, establishing themselves as business people, legislators, and other professions.
