Would we have had Slavery in the USA if a Black Man in the 1600’s didn’t WIN the RIGHT to Own Fellow Blacks as Slaves by the Courts???
Yes, we would have. It was going to happen. The historians have perverted the history on this to blame America, but at every and any point in the 1600s these were Courts of the Empire.
Slavery was in every colony of the Empire - at least any in the Western Hemisphere. Pick any one you want.(Antigua, Jamaica, etc. Any one) Slavery is how the Empire made its money. It was going to happen.
