Kanem–Bornu Empire
The Kanem–Bornu Empire existed in areas which are now part of Cameroon, Chad and Nigeria. It was known to the Arabian geographers as the Kanem Empire from the 8th century AD onward and lasted as the independent kingdom of Bornu (the Bornu Empire) until 1900. The Kanem Empire (c. 700–1380) was located in the present countries of Chad, Nigeria and Libya.[2] At its height it encompassed an area covering not only most of Chad, but also parts of southern Libya (Fezzan) and eastern Niger, northeastern Nigeria and northern Cameroon. The Bornu Empire (1380s–1893) was a state in what is now northeastern Nigeria, in time becoming even larger than Kanem, incorporating areas that are today parts of Chad, Niger, Sudan, and Cameroon. The early history of the Empire is mainly known from the Royal Chronicle or Girgam discovered in 1851 by the German traveller Heinrich Barth.

Theories on the origin of Kanem
Kanem was located at the southern end of the trans-Saharan trade route between Tripoli and the region of Lake Chad. Besides its urban elite, it also included a confederation of nomadic peoples who spoke languages of the Teda–Daza (Toubou) group.
In the 8th century, Wahb ibn Munabbih used Zaghawa to describe the Teda-Tubu group, in the earliest use of the ethnic name. Muhammad ibn Musa al-Khwarizmi also mentions the Zaghawa in the 9th century, as did Ibn al-Nadim in his Kitāb al-Fihrist[3] in the 10th-century. Kanem comes from anem, meaning south in the Teda and Kanuri languages, and hence a geographic term. During the first millennium, as the Sahara underwent desiccation, people speaking the Kanembu language migrated to Kanem in the south. This group contributed to the formation of the Kanuri people. Kanuri traditions state the Zaghawa dynasty led a group of nomads called the Magumi.[4]
This desiccation of the Sahara resulted in two settlements, those speaking Teda-Daza northeast of Lake Chad, and those speaking Chadic west of the lake in Bornu and Hausa-land.[5]:164
Founding by local Kanembu (Dugua) c. 700 AD
The origins of Kanem are unclear. The first historical sources tend to show that the kingdom of Kanem began forming around 700 AD under the nomadic Tebu-speaking Kanembu. The Kanembu were supposedly forced southwest towards the fertile lands around Lake Chad by political pressure and desiccation in their former range. The area already possessed independent, walled city-states belonging to the Sao culture. Under the leadership of the Duguwa dynasty, the Kanembu would eventually dominate the Sao, but not before adopting many of their customs.[6] War between the two continued up to the late 16th century.
Diffusionist theories
One scholar, Dierk Lange, has proposed another theory based on a diffusionist ideology. This theory was much criticised by the scientific community, as it seriously lacks of direct and clear evidences. Lange connects the creation of Kanem–Bornu with exodus from the collapsed Assyrian Empire c. 600 BC to the northeast of Lake Chad.[7][8] He also proposes that the lost state of Agisymba (mentioned by Ptolemy in the middle of the 2nd century AD) was the antecedent of the Kanem Empire.[9]
Duguwa or Dougouwa Dynasty (700–1086)
Kanem was connected via a trans-Saharan trade route with Tripoli via Bilma in the Kawar. Slaves were imported from the south along this route.[5]:171[10]
Kanuri tradition states Sayf b. Dhi Yazan established dynastic rule over the nomadic Magumi around the 9th or 10th century, through divine kingship. For the next millennium, the Mais ruled the Kanuri, which included the Ngalaga, Kangu, Kayi, Kuburi, Kaguwa, Tomagra and Tubu.[5]:165–168
Kanem is mentioned as one of three great empires in Bilad el-Sudan, by Al Yaqubi in 872. He describes the kingdom of "the Zaghāwa who live in a place called Kānim," which included several vassal kingdoms, and "Their dwellings are huts made of reeds and they have no towns." Living as nomads, their cavalry gave them military superiority. In the 10th century, al-Muhallabi mentions two towns in the kingdom, one of which was Mānān. Their king was considered divine, believing he could "bring life and death, sickness and health." Wealth was measured in livestock, sheep, cattle, camels and horses. From Al-Bakri in the 11th century onwards, the kingdom is referred to as Kanem. In the 12th century Muhammad al-Idrisi described Mānān as "a small town without industry of any sort and little commerce." Ibn Sa'id al-Maghribi describes Mānān as the capital of the Kanem kings in the 13th century and Kanem as a powerful Muslim kingdom.[11][4][5]
Sayfawa or Sefououwa Dynasty (1085–1846)
The Kanuri-speaking Muslim Saifawas gained control of Kanem from the Zaghawa nomads in the 9th century.[10]:26,109 This included control of the Zaghawa trade links in the central Sahara with Bilma and other salt mines. Yet, the principal trade commodity was slaves. Tribes to the south of Lake Chad were raided as kafirun, and then transported to Zawila in the Fezzan, where the slaves were traded for horses and weapons. The annual number of slaves traded increased from 1,000 in the 7th century to 5,000 in the 15th. Mai Hummay began his reign in 1075, and formed alliances with the Kay, Tubu, Dabir and Magumi. Mai Humai was the first Muslim king of Kanem, and was converted by his Muslim tutor Muhammad b. Mānī. This dynasty replaced the earlier Zaghawa dynasty. They remained nomadic until the 11th century, when they fixed their capital at Nijmi.[12][13][14][4][5]:170–172
According to Richmond Palmer, it was customary to have "the Mai sitting in a curtained cage called fanadir, dagil, or tatatuna...a large cage for a wild animal, with vertical wooden bars."[15]
Humai's successor, Dunama (1098–1151), performed the Hajj three times, before drowning at Aidab. His wealth included 100,000 horsemen and 120,000 soldiers.[5]:172[15]:91,163[10]:35
Mai Dunama Dabbalemi
Kanem's expansion peaked during the long and energetic reign of Mai Dunama Dabbalemi (1210–1259). Dabbalemi initiated diplomatic exchanges with sultans in North Africa, sending a giraffe to the Hafsid monarch, and arranged for the establishment of a madrasa of al-Rashíq in Cairo to facilitate pilgrimages to Mecca. During his reign, he declared jihad against the surrounding tribes and initiated an extended period of conquest with his cavalry of 41,000. He fought the Bulala for 7 years, 7 months, and 7 days. After dominating the Fezzan, he established a governor at Traghan, delegated military command amongst his sons. As the Sefawa extended control beyond Kanuri tribal lands, fiefs were granted to military commanders, as cima, or 'master of the frontier'. Civil discord was said to follow his opening of the sacred Mune.[10]:52–58[15]:92,179–186[5]:173–177[13]:190

By the end of the 14th century, internal struggles and external attacks had torn Kanem apart. War with the So brought the death of four Mai: Selemma, Kure Gana, Kure Kura, and Muhammad, all sons of 'Abdullāh b. Kadai. Then, war with the Bulala resulted in the death of four Mai in succession between 1377 and 1387: Dawūd, Uthmān b. Dawūd, Uthmān b. Idris, and Bukar Liyāu. Finally, around 1387 the Bulala forced Mai Umar b. Idris to abandon Njimi and move the Kanembu people to Bornu on the western edge of Lake Chad.[5]:179[15]:92–93,195–217[19][13]:190–191
But even in Bornu, the Sayfawa Dynasty's troubles persisted. During the first three-quarters of the 15th century, for example, fifteen Mais occupied the throne. Then, around 1460 Ali Gazi (1473–1507) defeated his rivals and began the consolidation of Bornu. He built a fortified capital at Ngazargamu, to the west of Lake Chad (in present-day Nigeria), the first permanent home a Sayfawa mai had enjoyed in a century. So successful was the Sayfawa rejuvenation that by the early 16th century Mai Idris Katakarmabe (1507–1529) was able to defeat the Bulala and retake Njimi, the former capital. The empire's leaders, however, remained at Ngazargamu because its lands were more productive agriculturally and better suited to the raising of cattle. Ali Gaji was the first ruler of the empire to assume the title of Caliph.[20][12]:159[10]:73[5]:180–182,205[15]:94,222–228
Mai Idris Alooma
Bornu peaked during the reign of Mai Idris Alooma (c. 1564–1596), reaching the limits of its greatest territorial expansion, gaining control over Hausaland, and the people of Ahir and Tuareg. Peace was made with Bulala, when a demarcation of boundaries was agreed, upon with a non-aggression pact.[21] Military innovations included the use of mounted Turkish musketeers, slave musketeers, mailed cavalrymen, and footmen. This army was organized into an advance guard and a rear reserve, transported via camel or large boats and fed by free and slave women cooks. Military tactics were honed by drill and organization, supplemented with a scorched earth policy. Ribāts were built on frontiers, and trade routes to the north were secure, allowing relations to be established with the Pasha of Tripoli and the Turkish empire. Between 1574 and 1583, the Borno sultan had diplomatic relations with the Ottoman sultan Murad III, as well as with the Moroccan sultan Ahmad al-Mansur, in the context of political tensions in the Sahara. The Borno sultan allied with the Moroccan sultan against the Ottoman imperialism in the Sahara.[22] Ibn Furtu called Alooma Amir al-Mu'minin, after he implemented Sharia, and relied upon large fiefholders to ensure justice.[5]:207–212,497–500[13]:190–191[12]:159[15]:94,234–243[10]:75
The Lake Chad to Tripoli route became an active highway in the 17th century, with horses traded for slaves. An intense diplomatic activity has been reported between Borno and the Pachalik of Tripoli at that time.[23] About two million slaves traveled this route to be traded in Tripoli, the largest slave market in the Mediterranean. As Martin Meredith states, "Wells along the way were surrounded by the skeletons of thousands of slaves, mostly young women and girls, making a last desperate effort to reach water before dying of exhaustion once there."[12]:159–160
Successors
Most of the successors of Idris Alooma are only known from the meagre information provided by the Diwan. Some of them are noted for having undertaken the pilgrimage to Mecca others for their piety. In the eighteenth century Bornu was affected by several long-lasting famines.[24][5]:500–508[15]:94–95,244–258 Aïr was independently operating the Bilma salt mines by 1750, having been a tributary since 1532.[4]:292[13]:190–191
The administrative reforms and military brilliance of Aluma sustained the empire until the mid-17th century when its power began to fade. By the late 18th century, Bornu rule extended only westward, into the land of the Hausa of modern Nigeria. The empire was still ruled by the Mai who was advised by his councilors (kokenawa) in the state council or "nokena".[25] The members of his Nokena council included his sons and daughters and other royalty (the Maina) and non-royalty (the Kokenawa, "new men"). The Kokenawa included free men and slave eunuchs known as kachela. The latter "had come to play a very important part in Bornu politics, as eunuchs did in many Muslim courts."[26]
During the 17th century and 18th century, Bornu became a centre for Islamic learning. Borno sultans developed a political legitimacy based on their religious charisma, in the context of the rise of Sufism in Sahel.[27] Islam and the Kanuri language was widely adopted, while slave raiding propelled the economy.[13]:190–191
Fulani Jihad
Around this time, Fulani people invading from the west were able to make major inroads into Bornu during the Fulani War. By the early 19th century, Kanem–Bornu 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–Bornu and inspired a trend toward Islamic orthodoxy.[15]:259–267[28]
Muhammad al-Kanemi
Muhammad al-Amin al-Kanemi 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 in 1814 a capital at Kukawa (in present-day Nigeria). Sayfawa mais remained titular monarchs until 1846. In that year, the last mai, in league with the Ouaddai Empire, precipitated a civil war, resulting in the death of Mai Ibrahim, the last mai. It was at that point that Kanemi's son, Umar, became Shehu, thus ending one of the longest dynastic reigns in international history. By then, Hausaland in the west, was lost to the Sokoto Caliphate, while the east and north were lost to the Wadai Empire.[29][13]:233[12]:194–195[15]:268
Shehu of Borno
Although the dynasty ended, the kingdom of Kanem–Bornu survived. Umar 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). Bornu began a further decline as a result of administrative disorganization, regional particularism, and attacks by the militant Ouaddai Empire to the east. The decline continued under Umar's sons. In 1893, Rabih az-Zubayr led an invading army from eastern Sudan and conquered Bornu. Following his expulsion shortly thereafter, the state was absorbed by the new Northern Nigeria Protectorate, in the sphere of the British Empire, and eventually became part of the independent state of Nigeria. From the arrival of the British, a remnant of the old kingdom was (and still is) allowed to continue to exist in subjection to the various Governments of the country as the Borno Emirate.[30][13]:307,318–319[28]:51
Rabih's invasion meant the death of Shehu Ashimi, Shehu Kyari and Shehu Sanda Wuduroma between 1893 and 1894. The British recognized Rabih as the 'Sultan of Borno', until the French killed Rabih on 22 April 1900 during the Battle of Kousséri. The French then occupied Dikwa, Rabih's capital, in April 1902, after the British had occupied Borno in March. Yet, based on their 1893 treaty, most of Borno remained under British control, while the Germans occupied eastern Borno, including Dikwa, as 'Deutsch Bornu'. The French did name Abubakar, the Shehu of Dikwa Emirate, until the British convinced him to be the Shehu of the Borno Emirate. The French then named his brother, Sanda, Shehu of Dikwa. Shehu Garbai formed a new capital, Yerwa, on 9 Jan. 1907. After WWI, Deutsch Bornu became the British Northern Cameroons. Upon Sheha Abubakar's death in 1922, Sanda Kura became Shehu of Borno. Then upon his death in 1937, his cousin, Shehu of Dikwa Sanda Kyarimi, became Shehu of Borno. As Vincent Hiribarren points out, "By becoming Shehu of the whole of Borno, Sanda Kyarimi reunited under his personal rule a territory which had been divided since 1902. For 35 years two Shehus had co-existed." In 1961, the Northern Cameroons voted to join Nigeria, effectively joining the frontiers of the kingdom of Bornu.[28]:51,63,71,87,106,133,137,144–145,157,164[15]:268–269
