By the twelfth century, most of the Lake Chad region lay under the authority of Kanem, a kingdom already known to Arab travellers and geographers from the ninth century onward. It was described as the only political entity of international renown between the Nuba of the Nile valley and Kaukau on the Niger Bend. The kingdom nevertheless contained a varied population living in separate clans and ethnic groups, and knowledge of polities beyond Kanem remained limited because chroniclers rarely recorded them.

Kanem’s dynastic history is preserved especially in the Dïwân of the sultans of Kanem-Bornu. The origins of this internal record probably reach the first half of the thirteenth century, when court chroniclers began writing down traditions that had previously circulated orally. They incorporated material reaching back to the end of the tenth century and continued updating the work until the end of the Sefuwa dynasty in the nineteenth century. Arab geographical accounts by al-Idrïsï, Ibn Sa'ïd and al-Makrïzï complement the Dïwân by providing descriptions of the region’s spatial organization.

The kingdom appears to have possessed a durable territorial and political structure before and after the transition from the Zaghawa to the Sefuwa dynasty. Manan served as the residence of the Dugawa kings for at least a century, while Djimi was the capital of the Sefuwa for three centuries. The later movement of the capital southward may reflect the growing influence of sedentary populations over the semi-nomadic peoples of the Sahel. When the Sefuwa were forced to leave Kanem at the end of the fourteenth century, Djimi lost its exceptional political status.

The surviving dynastic record gives little direct information about Kanem’s political institutions. During the earlier phase, members of the royal family probably occupied the most important offices, but conflicts between the sultan and his sons appear to have encouraged the later appointment of unrelated officials and local chiefs. By the end of the fifteenth century, the Sefuwa ruled twelve vassal kingdoms, although direct administration covered a smaller area and was probably exercised by dependants of the royal household. The king maintained both troops summoned for campaigns and professional soldiers.

Royal authority also shaped judicial practice. Justice was dispensed by the king despite the conversion of the rulers to Islam, although some reigns saw attempts to apply the sharīʿa, notably under Idrīs Alawoma. Kanem-Bornu’s political organization influenced neighbouring states, including Hausa polities, Kotoso and Bagirmi. This influence made Kanem more than a regional kingdom: it served as an institutional model within the central Sudan.

The population supporting the Kanem kings changed over time. Early Sefuwa rulers relied heavily on nomadic Tubu and Kay groups; later, sedentary Dabir and Kunkuna groups gained influence, while the Magomi royal lineage became increasingly dominant. The extract presents the Kanuri people as gradually emerging from this dynastic stock, while emphasizing that the state of Kanem-Bornu probably predated the formation of the people who later constituted its principal social base.

Kanem’s development was closely connected to trans-Saharan trade. Its position at the southern terminus of the caravan route through Fezzan and the oases of Kawar linked the Lake Chad region directly with the Mediterranean. The route may have existed since Roman times, while alternative corridors passed through the Kufra oases to the east and Takedda, later Agades, to the west. Control of these routes was therefore a central objective of Kanem’s rulers.

Kawar was especially valuable because Bilma and Agram, identified with Fachi, possessed exceptionally rich salt mines. Their owners earned substantial income from exporting salt to the Sahel, although the date of the mines’ first exploitation is unknown. In the first half of the twelfth century, Kawar contained small communities of traders and salt-miners led by Berbers or Tuareg wearing the lithām. Al-Idrïsī emphasized alum mining and marketing, but the extract suggests that regional salt commerce may already have been at least as significant by volume.

Fezzan was even more important for long-distance commerce because it stood at the intersection of major West African routes. Whoever dominated it could influence the north-south corridor between Ifriqiya, Tripoli and Kanem-Bornu, as well as east-west routes connecting Egypt with Ghana, Mali and Songhay. Kanem therefore occupied a strategic position within a wider commercial system, although its access to Mediterranean trade depended on controlling or securing distant intermediary zones.

Kanem-Bornu occupied a strategic position between the central Sudan, the Sahara, and North Africa. Control of Fezzan and the staging posts of the north-south caravan route connected Ifrikiya and Tripoli with Kanem-Bornu, while east-west routes linked Egypt with Ghana, Mali, and Songhay. The kingdom’s rulers therefore treated caravan security and control of passage as central political objectives, although the exact nature of their authority over some northern regions remains uncertain.

Trade with the north included slaves, elephant tusks, ostrich feathers, live animals, embroidered garments, and other specialized products. Imports included horses, textiles, fabrics, iron weapons, and probably copper and tin. Yet the kingdom’s prosperity did not depend solely on slave trading: agriculture, stock-raising, salt mining, and craftsmanship formed a broader productive base, while local weaving was sufficiently developed for cotton strips to function as a measure of value.

In the thirteenth century, Kanem’s rulers were reported to control Kawar and Fezzan, while other accounts described an empire stretching from Zella near Egypt to Kaka in the Lake Chad region. The kingdom also claimed authority over Takedda, the Tadjuwa, the Zaghawa, Djadja, and southern Berber groups. These reports indicate considerable influence, but they do not establish a uniformly organized territorial empire; the status of Fezzan and the eastern frontier remained variable and difficult to define.

The Sefuwa dynasty’s political expansion accompanied the spread of Islam. Earlier rulers and members of the dynasty were associated with pilgrimage, and Muslim royal wives appear in the dynastic record from the twelfth century. During the reign of Dunama Dibalami, Islam acquired a deeper institutional and social influence: the king was portrayed as a Muslim reformer, surrounded by jurists, associated with the destruction of the sacred object called mune, and possibly responsible for founding a madrasa in Cairo for Kanem’s subjects.

Dunama Dibalami’s reign, dated in the excerpt to approximately 1210–1248, combined religious reform with territorial ambition. He was credited with forcing certain central Sudanese peoples, including Berbers, to accept Islam, and he was buried at Zamtam after his death. Later evidence presents Kanem as religiously devout but politically weak, suggesting that the kingdom’s authority and military resources fluctuated even while adherence to the Maliki rite remained prominent.

From at least the twelfth century, groups associated with Kanem began moving westward into Bornu, west of Lake Chad. Earlier migrants included the Tomaghra, Tura, Kay or Koyam, Ngalma Dukko, and early Magomi groups. After the victorious expeditions of Idris Alawoma in the second half of the sixteenth century, many Tubu and Arabs also left Kanem for the more fertile and protected lands west of the lake.

The relationship between Kanem and Bornu before the late fourteenth century was complex. Bornu may initially have been an independent kingdom, but from the thirteenth century both regions appear to have come under the authority of the Sefuwa dynasty. Contemporary and later accounts nevertheless suggest that Bornu retained a degree of autonomy and that local rulers continued to matter, especially when Sefuwa power weakened.

At the end of the fourteenth century, the pastoral Bulala, already associated with the region of Lake Fitri, conquered Kanem and broke the Sefuwa monopoly over trade with North Africa. Dynastic conflict within the Sefuwa house intensified the crisis: several rulers were killed in fighting against the Bulala, while Umar b. Idris was forced to leave Djimi. The Sefuwa eventually established themselves permanently in Bornu, where their political tradition continued.
