Slave Exports from West and West-Central Africa, 1700–1810: new estimates of volume and distribution

Abstract

Using new evidence on the British, French and North American slave-carrying trades, this article seeks to revise Lovejoy's recently published estimates of the levels of slave exports from West and West-Central Africa in the eighteenth century. The figures suggest that Lovejoy's estimate of the total volume of slave exports from the west coast of Africa to America between 1700 and 1810 was probably reasonably accurate, being only 8 per cent lower than the total indicated here. However, the new data reveal temporal and coastal distributions of slave exports that differ substantially from those proposed by Lovejoy. In particular, they suggest that previous work significantly understated levels of slave exports between 1713 and 1740, and again in the 1760s and 1770s. Contrary to earlier findings, in fact, it appears that slave exports from the west coast of Africa to America in the decade prior to the War of American Independence were very similar to levels attained after 1783. Furthermore, in terms of coastal distributions, it seems that the Bight of Biafra and West-Central Africa, particularly the Loango coast, contributed much more substantially to the slave traffic to America during the early decades of the century than was previously assumed. These revisions of Lovejoy's figures have important implications for movements in slave prices in Africa and for assessing the demographic effects of the trade on the slave-supplying regions. In addition, they help to improve our understanding of the relationship between the slave trade and changes in sugar and other commodity production in America during the eighteenth century.
