The French, British, and Dutch were all major players, and much of the most lucrative trade was based on the trans-Atlantic slave trade. European ships established a ‘triangular’ trading route, bringing goods for trade from Europe to the West coast of Africa, then taking slaves across to the New World, and returning to Europe with agricultural commodities from there.
