A simple question for someone knowledgeable in this field. For the people enslaved, which of these two states could be said to have, on average, been the crueler, harsher master?
'Confederate' slavery includes the pre-Confederacy South as well.
Which generally treated their slaves more poorly and inhumanely (by modern standards)? Since Rome survived as a polity for so very much longer, we'll use the Pax Romana period as our chief example.
