Over 150,000 enslaved Africans died before reaching the New World

Evidence

Curtin, The Atlantic Slave Trade, op. cit., chap. 10. This figure, it must be recalled, is only an “estimate” of the number of deaths associated with the British slave trade in the eighteenth century. For France, during the same century, Robert Stein, who (without attribution) puts the French slave trade at 1,150,000, also claims that “no fewer than 150,000 died before reaching the New World, and many more died within a year or two of arrival.” — Cedric J. Robinson, Black Marxism_ The Making of the Black…, 1876
