History
The plains south of Lake Chad were home to the Sao, a people known from walled mounds, bronze work and terracotta figures along the lower Chari and Logone; the Kotoko fishing communities of the rivers trace their descent from them. From the 16th century the Baguirmi sultanate, with its capital at Massenya, rose on the lands east of the Chari, adopting Islam and raiding southwards for captives while paying tribute in turn to its stronger neighbours, Bornu and Ouaddaï.
In the 1890s the Sudanese warlord Rabih az-Zubayr overran the region and devastated Baguirmi, whose sultan, Gaourang, turned to France for help. Rabih was killed at the Battle of Kousséri in April 1900, fought just across the Logone, and the French commander Amédée-François Lamy also died there. A post founded that year on the east bank was named Fort-Lamy in his memory; it grew into the colonial capital, and in 1973 President Tombalbaye renamed it N'Djamena, after a nearby Arab village.
Since independence the capital has been the prize in Chad's power struggles. Fighting between rival northern factions in 1979 and 1980 wrecked much of the city and emptied it of residents, and rebel columns reached its streets in 2006 and 2008. Mayo-Kebbi, meanwhile, developed as part of the cotton-growing south, with a strong Christian and traditional-religion population and its own long-standing opposition politics.
