In 1725, King Agaja Trudo of Dahomey sent an emissary to England to express his desire that he wanted to trade with Europeans who were not slavers. The Kingdom of Dahomey under Agaja Trudo pursued an anti-slaving agenda, burning down trading posts at the slave ports of Allada and Whydah, besieging European forts that held slaves, punishing and executing European slavers, and blocking the overland routes by which slaves were brought from the interior to be sold in coastal markets. All of these actions undoubtedly had an adverse impact on commerce, but they were pursued nonetheless in the interest of restricting the slave trade.
From pg. 246 of
The Cambridge History of Africa, Vol. IV, edited by J. D. Fage, Richard Gray, and Roland Anthony Oliver:
King Agaja Trudo was also a rather far-sighted king who understood the importance of developing Dahomey's industrial capacity, and accordingly sent invitations for European artisans and craftsmen to set up shop in Dahomey and disseminate their skills and techniques. According to William Smith in his
A New Voyage to Guinea(London, 1744), Agaja Trudo was a highly enthusiastic patron of European industry, "So that if any Taylor, Carpenter, Smith, or any Sort of White Man that is free be willing to come here he will find very good Encouragement, and be much caress'd, and get Money, if he can be contented with this Life for a Time; his Majesty paying every Body extravagantly that works for him."
