The list author says: "34 books which, in order, cover world history (with an emphasis on non-Western cultures). I tried to use historical fiction novels as much as possible, but sometimes had to resort to non-fiction."
"9th-16th centuries: Ghana and Mali Empires. It's a children's book and takes some liberty with the facts, but I thought it would be a more engaging read than "The Royal Kingdoms of Ghana, Mali, and Songhay: Life in Medieval Africa.""
"15th-19th centuries: Songhai & Sokoto Empires. While it does not depict either the Songhai or Sokoto Empires, the first third of Roots gives a captivating account of growing up in 18th century Africa."
