I don't know if anybody nows about them but they were a ethnic group of Ghana who migrated to the actual tertitory of Burkina Faso and created a group of small but powerfull kingdoms. They had a very differenced social classes and a powerful cavalry. They controlled west african trade before French arrived at late XVIII century.
I want to proposse them as an new civilization.
