Wikipedia says: "The Benin Empire or Edo Empire (1440-1897) was a pre-colonial African state of modern Nigeria. It is not to be confused with the modern-day country called Benin." In Nigeria, Benin City still sits to mark the region, a central part of the slave-trading region of the 17th century.
I want to learn more of the kinds of world history I missed in middle and high school, either because it just wasn't taught (where do kids learn about the Benin Empire in high school history?) or because in all my moving around (five high schools, really and truly) in my youth, I missed out on some curriculum.
This is the sort of thing I've missed.
