CHALLENGES OF HISTORICAL RECORD
According to Ihediwa Nkemjika Chimee, the collected documents on history of Africa tended to focus on the activities Arabs and the Europeans in Africa (Chimee).
They focused on the coasts and trading routes, and some periods of some regions are not as recorded. According to Chimee, it will be the job of historians to recreate the timeline using instead:
languages
religions
philosophies
cosmology
arts & aesthetics,
music & dance,
warfare,
architectures,
farming,
astrology,
rituals,
navigation,
crafts & industries.
