Discuss new world slavery. where did the bulk of the world’s slaves come from prior to 1950? Discuss why and how this changed? Discuss the ways in which new world slavery was different from previous forms of slavery. Explain why did Europeans go to Africa for slaves? How did most Africans become enslaved? Describe the conditions of the middle passage. In detail, what was the impact of the slave trade on Africa? Finally, discuss the ways in which enslaved Africans positively impacted American culture.
