🤔I read the associated published research paper, and there's something that I don't understand.
The Roman army occupied England for a few hundred years. They were famous for having lots of African soldiers. Isn't it more likely that a Black Roman soldier settled, than Kent did trade with Africa?

Illustration of an Orù (pitcher) from c. AD 1456–1661 Orile-Owu, Nigeria.
Orù were mainly used for fetching water and preparing medicinal herbs. Burnt herb residue in the pitcher sheds light on medical practices in historic West Africa.

Just doubling up on this notice. I'd have to say that "adding" East Africa to our definitions of the #GlobalMiddleAges has been one of the biggest transformations in medieval studies of the past decade. Obviously, it was always there. But the work surveyed here shows how much we've been missing!
I see people are now sharing my old post about our very short intro textbook "'Ethiopia' and the World, 330-1500 CE" again, and as the original "free download" link has long since expired, let me recommend ... this one: www.academia.edu/119002798/_E...
