And of course Roman society was dependent on slavery (of other Europeans they conquered)
It really irks me that people do not include the historical long view of slavery and assume it was just a N. American invention.
The Romans, like just about all human societies, were equal-opportunity enslavers. They enslaved people from Europe, Africa and the Middle East. And they bought slaves from almost anywhere outside the Empire.
There was little or no racial or racist component to slavery in most societies before the 16th century in the Americas.
Your politically-correct dictionary will not tell you this, but where o you think the term “barbarian” came from?
