Secondly, the economic perspective of keeping these people as prisoners.
It is costly enough for the Ashanti to take heed of their own people, so for them to add these group of people who the Ashanti don’t even like to the equation, it is just bizarre. The Fante already caused the Ashanti lost, why waste more resources. Your own people would never put into effect a war in which the tribe (Ashanti) would lose assets. It could be argue that the captive tribe can be inserted into the Ashanti, but the yet again the Ashanti will need to have special surveillance, train guards, be on the lookout for revolutionary movements, this could be a very painful and draining journey for them. The answer to their problem is pretty practical and simple, “Get rid of the problem” the Ashanti obtain weapons among other goods, and I ship my problem away, end of story. Additionally, Ashanti didn’t trade their cousins and woman, they sold people who according to the Ashanti weren’t adding anything to their community. Thus these people, or rival tribes in their eyes weren’t “their
own”.
What narrative/ story of history does the movie main argument challenge? “Money is the motive”, the main argument of the story is plain and simple. The repercussion of the slave trade economically wise in tribes as the Ashanti, the social pyramided, the law of the jungle, the strongest survive and so forth are some of the cliché that apply to these circumstances. Likewise, the Ashanti were the ones on top of the pyramid as a result they got to do what they thought it was convenient for the economics of their community, resulting in the trading of prisoners in exchange of guns and goods.
