Because some african weren't christians
There was no slavery in Africa before the Europeans got involved!
the europeans supported slavery because of the change from tobacco to sugar,this required a vast amount of unskilled labour.
It was much worse than slavery in the America's.
The indians
Arabs did enslave africans long before the europeans, however the europeans did bring chattell slavery to north America, where it evolved and became the peculiar institution that later begat Jim crow....
The religious and intellectual developments that led some Europeans and some American to question and criticize the institution of slavery were the crusades and the Enlightenment and Revolution. The eighteenth century crusade against slavery originated from the changes in religious and intellectual outlooks on slavery among small but influential groups in both America and Europe. The Enlightenment questioned the wisdom of having existing institutions that it chewed away at older defenses of slavery (mostly the unchanging social hierarchy). The general Enlightenment rhetoric of equality stood in sharp contrast to the radical inequality of slavery.
slavery in the Americas started when the Europeans came over and they started to enslave the native people
Slavery existed in African trade long before europeans arrived

I sure hope they don't offer Europeans. New York banned slavery in 1799. Leave the poor Europeans alone.
The aboriginal people practised slavery for perhaps thousands of years before the arrival of Europeans.
Slavery in pre-colonial Africa was diverse and varied across different regions. In some societies, slaves were assimilated into the community and could rise to positions of power, while in others they were used for manual labor. Slavery was often a result of warfare, debt, or punishment, and slaves could be traded both within Africa and with neighboring regions.
