Not nations, but only 13 of the US states allowed slavery. Alabama, Arkansas, Delaware, Florida, Georgia, Kentucky, Louisiana, Maryland, Mississippi, Missouri, North Carolina, South Carolina, Tennessee, Texas, and Virginia. So roughly 26% of the total states of the US, however since there were only 36 states at the time of the Civil War, that would bring the percentage of slavery supporting states to a whopping 36.111R% of the existing states at the time.
It seems very strange that Oklahoma isn’t on that list. I know why, but still.
