The Dutch share in the Atlantic slave trade has been assessed largely by means of speculation. This article relies extensively on documents of the Dutch West Indian Companies (WIC), which maintained a dozen or more trading stations on the Guinea Coast, and became the principal agents of the Dutch slaving activities. For approximately 16 years (1630–1795), the Dutch played a substantial role in the Atlantic slave trade. Based on the combined criteria of available documentary evidence and fluctuating techniques of the trade, the Dutch slave trade has been outlined in three successive stages, viz. the monopoly of the first WIC (1630–74), the monopoly of the second WIC (1675–1734), and the free trade period (1735–95). Information on the first period is scarce, leaving much to speculation, but for the years after 1675 a reliable assessment is possible.
On the whole, the Dutch share constituted about 10 per cent of the overall Atlantic slave trade. Annual averages (calculated by decades) ranged from less than a thousand to over 6,000 slaves. During selected years in the 1630s and 1640s, the Dutch may have become the single most active slave trading nation, but toward the end of the seventeenth century the Dutch trade stagnated while other nations drastically increased their volume. When the WIC began to relinquish its monopoly of the slave trade (1730), the volume of the Dutch trade increased until it reached its peak during the 1760s and early 1770s. As a result of the American Revolutionary War and the ensuing Anglo-Dutch war, Holland's participation in the slave trade virtually came to a halt. Feeble efforts to revivie the trade in subsequent decades failed as a result of the unstable political situation in Europe following the revolution in France and also due to the movement to suppress the slave trade.

6 The bulk of these minutes were preserved in Elmina until 1872, when the Dutch surrendered their West African trading posts to the English. The documents that had been kept in Africa were then taken to the Netherlands, where they are currently kept in the collection ‘Archief van de Nederlandse Bezittingen ter Kuste van Guinea’ in the Rijksarchief at The Hague.

18 The frequently cited work of Unger (see notes 2 and 25) has thus far been the most authoritative on the slaving activities of the old WIC, whose documents he consulted, although his articles focus on the eighteenth century free trade of Middelburg. Unfortunately, Unger's writings have only been published in Dutch.

25 It appears that the WIC rarely purchased child slaves during the seventeenth century, but that this category of slaves rose to nearly ten per cent during the first half of the eighteenth century. In subsequent years, according to Unger, Dutch free traders averaged as many as 22.5 per cent non-adult slaves in their cargoes.
