KANEM-BORNO: This was the largest centralized state in the country and its ruling dynasty, the Sayfawa, ruled for about one thousand (1,000) years. That was then when lizards were in ones and twos when the state emerged in Kanem to the North-east of Lake Chad.
However, the Kanem-Borno Empire collapsed at the end or the 14th century; thus, its rulers migrated to the west of Lake-Chad and then formed another state by name Borno.
Meanwhile, the history of the Kanem-Borno Empire can be divided into two phases -the first and second Kanuri empires.
