"The rise of Benin...is closely connected with the European demand for slaves...The profits from the trade with the Europeans gave the rulers and merchants of Benin an incentive and also, in the form of firearms, the means, to extend their rule...By the end of the seventeenth century, however, the continual warfare was destroying the prosperity and even the structure of the state...Large parts of the city were deserted and left to crumble into ruins. Trade, even the trade in slaves, declined, and, as European traders came ever less frequently to the city, so the purpose of slave-raids became increasingly to provide victims for human sacrifices. Eventually, of all the greatness of Benin, all that survived was the unchecked and self-destructive lust of its rulers for power and human booty."
