Andrew Delbanco in The New York Times:
Between the early 16th century and the middle of the 19th, more than 12 million human beings were shipped against their will from Africa to the New World and sold into slavery. An untold number died at different stages of the journey — overland in Africa, during the “middle passage” at sea or soon after arrival. Among those who perished, most died of disease, some by suicide and still others from wounds or execution following failed revolts.
For nearly four centuries, as Greg Grandin writes in his powerful new book, slavery was the “flywheel” that drove the global development of everything from trade and insurance to technology, religion and medicine. To read “The Empire of Necessity” is to get a sort of revolving scan from the center of the wheel. What we see is an endless sequence of human transactions — the production and exchange of meat, sugar, rice, cotton, tobacco, gold, among many other things — all connected, through slavery, by linkages whose full extent cannot be discerned from any point along the way. Slaves, Grandin writes, “were at one and the same time investments (purchased and then rented out as laborers), credit (used to secure loans), property, commodities and capital.”
