Kanem-Bornu Wars of ExpansionChad / Nigeria / Niger · c. 900–1800"Turn from the Niger bend to Lake Chad, where kings called mai kept an empire alive longer than many dynasties keep a house."Kanem rose where desert and savanna traded breath, drawing strength from Lake Chad, caravan routes, Islam, cavalry and the Sayfawa court at Njimi.The lesson the elders kept: Some states endure because they are not built like stone, but like a caravan that knows when to shift camp. Kanem-Bornu's power was not only expansion; it was recovery.
