Here is a very good 2009 video lecture (at Emory U.) by a leading scholar of slavery and its economic impact, as well as the resistance to it–Dr. David Brion Davis, of Yale University.
This one is called “American and British Slave Trade Abolition in Perspective.” This would be very good for use in a course on U.S. history, and/or racism/slavery. It is in six parts, and here are the summaries:
The historical contexts of African slavery in the Americas and the relationship with free market forces and the “New World” global economy.
The connections between enslaved African labor, trans-Atlantic trade, and the increasing availability of luxury goods for mass market consumption. How did anti-slavery movements arise in this growing market context?
Three major factors led to the U.S. and British decisions to abolish the trade of enslaved Africans: revolutionary changes in moral perceptions of slavery, Anglo American antipathy towards a growing African American population, and the population growth rate of enslaved African Americans in North America.
The North American “moral luxury” of condemning the trade of enslaved Africans while supporting domestic slavery; the increasing political enthusiasm for white immigration over black enslaved labor; the impacts of the French and Haitian Revolutions on trade abolition developments.
The political and moral debates between delegates from northern states and southern slaveholding states after the Revolutionary War that led to U.S. abolition of the trans-Atlantic slave trade in 1808.
A comparison of the impacts of the U.S. and British decisions to abolish the trans-Atlantic slave trade and the debates over what to do with the “contraband” of enslaved Africans intercepted in the newly illegal trade.
