The Early Modern Period saw the rise of witch hunts, colonization, and slavery.
Witch hunts happened in the medieval period. So did events like Spain casting all the Jews out of their Kingdom, and England doing the same in I believe the 1300s.
Colonization and slavery go as far back as Ancient Egypt if not even earlier than that. I mean, remember, the Jews were Egyptian slaves.
The Roman Empire were colonizers and slavers, as were the Ancient Greeks.
The African Nations and Europeans of the early Modern Period did not create slavery, they just continued it and made it worse and made it even more perverse. And you really only start to see African Americans as going from indentured servants (which were a class that even their fellow whites of lower economic standing could find themselves in) who had a chance of freedom, to becoming true slaves, around the dawning of the Enlightenment era in the later 1600s and early 18th century.
