The Kanem-Bornu Empire was a large African state which existed from the 9th century through the end of the 19th century and which spanned a region which today includes the modern-day countries of Niger, Chad, Cameroon, and Nigeria. The empire was founded by the Zaghawa nomadic people, who may have been the first in the central Sudan to acquire and make use of iron technology and horses.
Kanem was situated north east of Lake Chad. Its early origins are thought to lie in the 7th century with the settlement of the Zaghawa people. In the early 11th century, the Kanuri-speaking Sefawa dynasty was established, displacing the Zaghawa.
The empire was first mentioned by Arab chroniclers in the 9th century, and by the 10th century the ruler of Kanem had control of the Kawar Oases, a vital economic asset. The political structure of the Kanem empire had most likely grown out of rival states coming under the control of the Zaghawa. In the 11th century the Zaghawa clans were driven out by Humai ibn Salamna, who founded the kingdom of Kanem with a capital at Njimi. The Saifwa dynasty was established, a dynasty which ruled for 771 years—-the longest known reign in history.
Saifwa rulers (known as mais) claimed they were descended from a heroic Arabic figure, and the dynasty greatly expanded the influence of Islam, making it the religion of the court. Wealth came largely through trade, especially in slaves, which was facilitated by the empire’s position near important North-South trade routes.
Kanem converted to Islam under the ruler Hu or Hawwa (1067-71). There is some speculation that this ruler might have been a woman. The faith was not widely embraced until the 13th century. Certainly, Muslim traders would have played a role in bringing Islam to Kanem.
The wealth of Kanem derived from the ability of its rulers to control trade in the region. Their main exports were ostrich feathers, slaves and ivory. Their exports were crucial to their power and ability to dominate their neighbour. They rode horses, which they imported from the north.
Kanem reached the height of its power under the long rule of Mai Dunama Dibalami (1210-1248). His cavalry numbered over 40,000. But over the next hundred years, a combination of overgrazing, dynastic uncertainties and attacks from neighbours led the rulers of Kanem to move to Borno, which had previously paid tribute to Kanem. At this point, the state is sometimes referred to as Kanem-Borno.
Bornu expanded territorially and commercially, but increasing threats from other rival states, drought, trade problems, and rebellious Fulani groups eroded state control. Muhammad al-Amin al-Kanemi, a Muslim cleric, eventually defeated the rebellious Fulani and built a new capital at Kukawa in 1814.
His successors ended the Saifwa dynasty and the Kanem-Bornu Empire when they killed the last mai in 1846. Al-Kanemi’s Shehu dynasty was short-lived, and succeeded by slaver and warlord Rabih Zubayr, who was defeated by the French in 1900.
