Yesterday, a Declaration of the trafficking of enslaved Africans and Racialized Chattel Enslavement of Africans as the Gravest Crime against Humanity was voted at UNO. As usual, Israel and the USA voted against. How did your country vote? Any thoughts about it?
I think scale is the issue.
Basically, it was legal to rape, murder and/or kidnap Africans. It was so profitable that the main slave dealers were African tribes/nations who would sell their prisoners of war to the slave trade - thus encouraging more war and more slavery.
Estimates of African deaths (on the low side) are double that of the Holocaust.
This went on for 400 years. (Nazi power lasted only about 12 years by comparison.)
And even to this day, the African slave trade is responsible for much of the racism and division we see. So, yeah, slave trade shaped our world in many ways.
