‘Slavery was not started by Confederates, no, the wonderful Middle Eastern Muslims take that honor.’
Never heard of the Roman Empire the Alexandrian Empire, the Persian, Assyrian, Chinese, Japanese, or Egyptian Empires, all of which had slaves, along with most other countries in history. The Muslims had a lot to do with the rise of Black African slavery of course.
I am unaware of any group organized at the state level prior to the 19th century that did not have slavery as one of its institutions. Some, such as Rome and Sparta, were economically based on slavery, as was the American South.
If nothing else, in the vast majority of human societies the status of women has differed little from slavery.
