Actually as wars go it was pretty civil; brutal, bloody, one of the greatest blood baths in history, but the combatants were civil to each other when they weren't killing each other. More Americans died in that war than Africans were brought to this country as slaves. Only 2% of Africans sold as slaves came to the colonies which would become the US. The majority of slaves died in gold and silver mines in South America or on sugar plantations in the Indies, east and west Indies. The ones who made it to the US were the lucky ones. There is an English college professor with a lot of books about the slave trade on Amazon, one is called 'Black Ivory, a history of the African Slave Trade'. It mentions that slavery outside the US colonies was basically a sentence to death at hard labor but demographics show that that did not happen in the US colonies. According to NPR, Benjamin Franklin decided to support the American Revolution because when he visited Ireland he found that the Irish in Ireland were treated worse under English rule than black slaves were by white slave owners in the US colonies. The slave trade was started to stop the genocide of Native Americans in South America. Catholics would convert them, then Spanish Aristocrats would work them to death in the mines. It was frustrating for Catholic monks so they suggested buying slaves from Africa. England one a monopoly on the trade in a war with Spain and then pushed slaves around the world like it pushed opium in China. When a US colony would pass a law banning the importation of slaves the English Parliament would pass a law requiring the colony to buy slaves. Still for most of the period of the slave trade, the US colonies were too poor to play an important role, and only 2% of the slaves ever made it here.
