This month, it is important to remember again the history and scope of the Slave Trade through and out of Africa; and the materials below can be of help to any of us. Note that the maps below illustrate the various trade routes, their movement over land and water, and their destinations within Africa, the Americas, Asia, and Europe.
For an additional interactive map illustrating the movement of slave ships across space and time, with emphasis on the TransAtlantic routes during the primary trade period, please see this article at Slate.
Much of the data for the map above is culled from two well-known and frequently referenced sources, both a product of decades of collaborative scholarly research: The Trans-Atlantic Slave Trade Database and African Origins. A synopsis of the history and recommended uses of both databases can be found at the Hutchins Center for African & African American Research.
More recently, the National Geographic Society has presented an interactive History of Slavery in the United States, in the form of a timeline allowing one to peruse "America's 'peculiar institution.'"
And perhaps most importantly, one can get a sense of the growing scholarship connecting the slave trade and plantation slavery with modern economic systems in this Public Seminar entry titled, "Slaves: The Capital that made Capitalism."
