The Kanem Empire originated in the ninth century A.D. to the northeast of Lake Chad. It was formed from a confederation of nomadic peoples who spoke languages of the Teda- Daza (Toubou) group. One theory, based on early Arabic sources, suggests that the dominance of the Zaghawa people bound the confederation together. But local oral traditions omit the Zaghawa and refer instead to a legendary Arab, Sayf ibn Dhi Yazan--believed by some to have been a Yemeni-- who assumed leadership of the Magoumi clan and began the Sayfawa dynastic lineage. Historians agree that the leaders of the new state were ancestors of the Kanembu people. The leaders adopted the title mai, or king, and their subjects regarded them as divine.
One factor that influenced the formation of states in Chad was the penetration of Islam during the tenth century. Arabs migrating from the north and east brought the new religion. Toward the end of the eleventh century, the Sayfawa king, Mai Humai, converted to Islam. (Some historians believe that it was Humai rather than Sayf ibn Dhi Yazan who established the Sayfawa lineage as the ruling dynasty of Kanem.) Islam offered the Sayfawa rulers the advantages of new ideas from Arabia and the Mediterranean world, as well as literacy in administration. But many people resisted the new religion in favor of traditional beliefs and practices. When Humai converted, for example, it is believed that the Zaghawa broke from the empire and moved east. This pattern of conflict and compromise with Islam occurs repeatedly in Chadian history.
Prior to the twelfth century, the nomadic Sayfawa confederation expanded southward into Kanem (the word for "south" in the Teda language). By the thirteenth century, Kanem's rule expanded. At the same time, the Kanembu people became more sedentary and established a capital at Njimi, northeast of Lake Chad. Even though the Kanembu were becoming more sedentary, Kanem's rulers continued to travel frequently throughout the kingdom to remind the herders and farmers of the government's power and to allow them to demonstrate their allegiance by paying tribute.
Kanem's expansion peaked during the long and energetic reign of Mai Dunama Dabbalemi (ca. 1221-59). Dabbalemi initiated diplomatic exchanges with sultans in North Africa and apparently arranged for the establishment of a special hostel in Cairo to facilitate pilgrimages to Mecca. During Dabbalemi's reign, the Fezzan region (in present-day Libya) fell under Kanem's authority, and the empire's influence extended westward to Kano, eastward to Wadai, and southward to the Adamawa grasslands (in present-day Cameroon). Portraying these boundaries on maps can be misleading, however, because the degree of control extended in ever-weakening gradations from the core of the empire around Njimi to remote peripheries, from which allegiance and tribute were usually only symbolic. Moreover, cartographic lines are static and misrepresent the mobility inherent in nomadism and migration, which were common. The loyalty of peoples and their leaders was more important in governance than the physical control of territory.
Dabbalemi devised a system to reward military commanders with authority over the people they conquered. This system, however, tempted military officers to pass their positions to their sons, thus transforming the office from one based on achievement and loyalty to the mai into one based on hereditary nobility. Dabbalemi was able to suppress this tendency, but after his death, dissension among his sons weakened the Sayfawa Dynasty. Dynastic feuds degenerated into civil war, and Kanem's outlying peoples soon ceased paying tribute.
By the end of the fourteenth century, internal struggles and external attacks had torn Kanem apart. Between 1376 and 1400, six mais reigned, but Bulala invaders (from the area around Lake Fitri to the east) killed five of them. This proliferation of mais resulted in numerous claimants to the throne and led to a series of internecine wars. Finally, around 1396 the Bulala forced Mai Umar Idrismi to abandon Njimi and move the Kanembu people to Borno on the western edge of Lake Chad. Over time, the intermarriage of the Kanembu and Borno peoples created a new people and language, the Kanuri.
But even in Borno, the Sayfawa Dynasty's troubles persisted. During the first three-quarters of the fifteenth century, for example, fifteen mais occupied the throne. Then, around 1472 Mai Ali Dunamami defeated his rivals and began the consolidation of Borno. He built a fortified capital at Ngazargamu, to the west of Lake Chad (in present-day Niger), the first permanent home a Sayfawa mai had enjoyed in a century. So successful was the Sayfawa rejuvenation that by the early sixteenth century the Bulala were defeated and Njimi retaken. The empire's leaders, however, remained at Ngazargamu because its lands were more productive agriculturally and better suited to the raising of cattle.
Kanem-Borno peaked during the reign of the outstanding statesman Mai Idris Aluma (ca. 1571-1603). Aluma (also spelled Alooma) is remembered for his military skills, administrative reforms, and Islamic piety. His main adversaries were the Hausa to the west, the Tuareg and Toubou to the north, and the Bulala to the east. One epic poem extols his victories in 330 wars and more than 1,000 battles. His innovations included the employment of fixed military camps (with walls); permanent sieges and "scorched earth" tactics, where soliders burned everything in their path; armored horses and riders; and the use of Berber camelry, Kotoko boatmen, and iron-helmeted musketeers trained by Turkish military advisers. His active diplomacy featured relations with Tripoli, Egypt, and the Ottoman Empire, which sent a 200-member ambassadorial party across the desert to Aluma's court at Ngazargamu. Aluma also signed what was probably the first written treaty or cease-fire in Chadian history. (Like many cease-fires negotiated in the 1970s and 1980s, it was promptly broken.)
Aluma introduced a number of legal and administrative reforms based on his religious beliefs and Islamic law (sharia). He sponsored the construction of numerous mosques and made a pilgrimage to Mecca, where he arranged for the establishment of a hostel to be used by pilgrims from his empire. As with other dynamic politicians, Aluma's reformist goals led him to seek loyal and competent advisers and allies, and he frequently relied on slaves who had been educated in noble homes. Aluma regularly sought advice from a council composed of heads of the most important clans. He required major political figures to live at the court, and he reinforced political alliances through appropriate marriages (Aluma himself was the son of a Kanuri father and a Bulala mother).
Kanem-Borno under Aluma was strong and wealthy. Government revenue came from tribute (or booty, if the recalcitrant people had to be conquered), sales of slaves, and duties on and participation in trans-Saharan trade. Unlike West Africa, the Chadian region did not have gold. Still, it was central to one of the most convenient trans-Saharan routes. Between Lake Chad and Fezzan lay a sequence of well-spaced wells and oases, and from Fezzan there were easy connections to North Africa and the Mediterranean Sea. Many products were sent north, including natron (sodium carbonate), cotton, kola nuts, ivory, ostrich feathers, perfume, wax, and hides, but the most important of all were slaves. Imports included salt, horses, silks, glass, muskets, and copper.
Aluma took a keen interest in trade and other economic matters. He is credited with having the roads cleared, designing better boats for Lake Chad, introducing standard units of measure for grain, and moving farmers into new lands. In addition, he improved the ease and security of transit through the empire with the goal of making it so safe that "a lone woman clad in gold might walk with none to fear but God."
The administrative reforms and military brilliance of Aluma sustained the empire until the mid-1600s, when its power began to fade. By the late 1700s, Borno rule extended only westward, into the land of the Hausa. Around that time, Fulani people, invading from the west, were able to make major inroads into Borno. By the early nineteenth century, Kanem-Borno was clearly an empire in decline, and in 1808 Fulani warriors conquered Ngazargamu. Usman dan Fodio led the Fulani thrust and proclaimed a jihad (holy war) on the irreligious Muslims of the area. His campaign eventually affected Kanem-Borno and inspired a trend toward Islamic orthodoxy. But Muhammad al Kanem contested the Fulani advance. Kanem was a Muslim scholar and non-Sayfawa warlord who had put together an alliance of Shuwa Arabs, Kanembu, and other seminomadic peoples. He eventually built a capital at Kukawa (in present-day Nigeria). Sayfawa mais remained titular monarchs until 1846. In that year, the last mai, in league with Wadai tribesmen, precipitated a civil war. It was at that point that Kanem's son, Umar, became king, thus ending one of the longest dynastic reigns in regional history.
Although the dynasty ended, the kingdom of Kanem-Borno survived. But Umar, who eschewed the title mai for the simpler designation shehu (from the Arabic "shaykh"), could not match his father's vitality and gradually allowed the kingdom to be ruled by advisers (wazirs). Borno began to decline, as a result of administrative disorganization, regional particularism, and attacks by the militant Wadai Empire to the east. The decline continued under Umar's sons, and in 1893 Rabih Fadlallah, leading an invading army from eastern Sudan, conquered Borno.
