I’m not sure why you talked about the pre-colonial slave trade specifically, but it read like you felt this article neglected the point in favor of a rosier image of the region’s history. The article does mention the perpetuation of colonial structures by East Africans after the British left (and cites an article by Kusimba). There’s no specific mention of the pre-colonial slave trade in this piece, but Kusimba has written about the “ancient practices that can be traced back more than two millennia in Africa.”[1] I find it unlikely he meant to gloss over this, and instead probably just focused on another time period.
Just to say so explicitly, I’m genuinely curious about how you perceived this article and why!

I’m curious which portion of the article you’re referring to? I’m not sure what point from the article your comment is meant to address.
