| | Nigeria (09/06) |
 | | Before the colonial period, the area which comprises modern Nigeria had an eventful history. |
 | | In the northern cities of Kano and Katsina, recorded history dates back to about 1000 AD. |
 | | In the centuries that followed, these Hausa kingdoms and the Bornu empire near Lake Chad prospered as important terminals of north-south trade between North African Berbers and forest people who exchanged slaves, ivory, and kola nuts for salt, glass beads, coral, cloth, weapons, brass rods, and cowrie shells used as currency. |
