Racism and slavery have been going on for 1000's of years going back as far as the Carthaginian Empire, 650 BC, Achaemenid Empire, 550 BC, then the ancient Egyptians, Romans, ancient Persians, the Mughals of India/Pakistan/Afghanistan, many counties of native Africa long before it was prevalent in Western Europe and the Americas.

Unfortunately, it will continue as long as man is on the planet.
