The American revolution was the 10th European slave revolt since 1638.
Nearly all the slaves, mostly African, who came into the Union beyond the original 13 colonies were already slaves and were emancipated, with massive european bloodshed, within 2 generations of statehood. Conversely, all the white slaves were slaughtered by freed black slaves throughout the south and Carribean.
