The true freedom of slaves didn’t happen until almost a hundred years later in 1963 ... and it was a Republican that did it. The Democrats held on to slavery with that “Separate but Equal” nonsense plus that segregation stuff. The black population votes Democrat that kept them in slavery and to a religion that sold them into it.
President Woodrow Wilson (as just one example) was 10 times the racist that President Jefferson Davis or any other high-level Confederate probably ever was.
The actual, amazing untold story here is that WITHOUT government forced redistribution by 1880 blacks owned 10% of the land in the south-—this coming from people who had been in chains a mere 15 years earlier. That is an astounding record.
