Medieval period (c. 700–1472) Origin and early history (c. 700–1000) warriors and a chief, by
Élisée Reclus (1892)|left The early history of Kanem is poorly known and subject to debate. The empire is believed to have originated in the lands between
Lake Chad and the
Bahr el Ghazal River, with a core territory in the region of Kanem (northeast of Lake Chad). Lake Chad was positioned along key trade routes, ideally situated between Egypt and Sudan in the east, various West African states in the west, and the
Sahara Desert in the north. Humans lived in the inner
Chad Basin at least as far back as the 6th millennium BCE. The region is known to have acquired iron-smelting technology by the 5th century BCE and experienced increased agricultural activity around that time as well as the formation of permanent villages. By the 5th century CE, the people in Kanem had acquired the
camel, either from
North Africa or the
Nile Valley. The appearance of the camel is believed to have facilitated the rich
trans-Saharan trade, though archaeological evidence of this trade in pre-Islamic times is next to non-existent. Control of this trade led to the rise of stratified societies which eventually coalesced into kingdoms. One scholar, Dierk Lange, has proposed that Kanem's establishment was connected to refugees from the fall of the
Neo-Assyrian Empire in the 7th century BCE, though this hypothesis has been criticised for lack of evidence and has found no acceptance among other researchers. The process of state formation in Kanem is in large part unknown. The history of the Kanem Empire may go back as far as the 8th century and perhaps even earlier. The empire's foundation is typically dated to 700, though some place it as late as c. 900 or as early as c. 600. The earliest known written record of Kanem comes from the Arab geographer
Al-Ya'qubi in 872. The empire's first capital was probably
Njimi, east of Lake Chad, and its rulers assumed the title
mai. The site of Njimi has never been satisfactorily located, despite attempts to find it since the mid-19th century. Although only limited surveys of the original core of the empire have been conducted, the capital may have been built of impermanent materials. Some later Arab sources suggest that it was a "city of tents" in its original incarnation. Archaeological evidence from
Koro Toro suggests that the region surrounding Kanem saw a considerable development of iron production between c. 500 and c. 1000, the formative centuries of Kanem. The empire was probably founded by the
Zaghawa people, pastoralists from the
Ennedi Plateau, but grew to encompass several other ethnic groups, such as the
Toubou people in the north. The empire consisted of various groups, including nomadic pastoralists, agriculturalists, and people accustomed to iron-working and horsemanship. The different groups eventually gave rise to the
Kanembu people, who speak the
Nilo-Saharan Kanembu language. The early empire grew wealthy and powerful through the export of slaves in exchange for horses, and the raiding of its neighbors. The early Kanem Empire was ruled by the
Duguwa dynasty, an aristocratic group who may have chosen
mais among themselves. Arab sources connect the Duguwa to the Zaghawa. It has also been suggested that they were Kanembu. The modern-day
Haddad people in Chad may also have some historical connection to the Duguwa dynasty. Later legend, reflecting a desire to connect Kanem to the greater
Islamic world, claimed that the Duguwa were descendants of migrants from the Arabian peninsula, who intermarried with the indigenous people around Lake Chad. Later tradition identifies
mai Susam as the first ruler of the empire. The Duguwa dynasty gets its name from the empire's third ruler, Dugu (or Duku). The political history of the Kanem–Bornu Empire is largely reconstructed through the
girgam, the empire's royal chronicle. The
girgam was preserved through oral tradition before transcriptions by European scholars in the mid-19th century. The
girgam is not entirely reliable since it was preserved orally, incorporates some Biblical figures in its early sections, and contains some contradictions between different versions. There is however a large degree of agreement across different versions of the
girgam as to the names of rulers and the lengths of their reigns.
Conversion to Islam (c. 1000–1380) Islam reached modern-day
Chad already in the time of the
Umayyad Caliphate (661–750), when Arab raiders reached
Fezzan and the
Tibesti Mountains. The religion was probably introduced to Kanem from the north by either the Toubou people or trans-Saharan traders. Islam was probably an important influence within the empire from as early as the mid-8th or 9th century. Portions of the population may have early on converted to
Ibadi Islam, as happened in
Gao to the northwest. The early rulers of Kanem approached Islam carefully since they perceived the religion to contain some dangerous ideas, such as the equality of all believers before God. In traditional local religions, the ruler was often accorded superhuman powers and unlimited authority. The first Muslim ruler of Kanem was the 11th-century
mai Hu (or Hawwa), who may have been a woman. Hu's successor,
Selema I, may have been overthrown in the second half of the 11th century by
mai Hummay, who established the new
Sayfawa dynasty. Hu and Selema may have been Ibadi Muslim, whereas Hummay's dynasty was
Sunni Muslim. The Sayfawa were Kanembu in origin but claimed descent from the Yemeni noble
Sayf ibn Dī Yazan, a well-known legendary hero in the medieval Islamic world. Sayf and Susam were identified as the same figure in later Kanem–Bornu tradition. Other African dynasties of this time sometimes made similar claims to Arab origin as a source of prestige. Later tradition credited the conversion of the Sayfawa dynasty to a scholar named Muhammad bin Mani, from whom many later Kanemi and Bornuan scholars and religious officials claimed descent.''''
Following the conversion to Islam by the rulers, conversions also increased among the general populace. Since Islam did not permit the enslavement of Muslims, it was not in the interest of the mai''s to force conversion beyond certain limits, so as to continue to facilitate the need for slaves in local and trans-Saharan markets. The trans-Saharan trade sustained the empire, which was able to levy taxes and duties on trade goods. Through the trade passing through the empire, Kanem had access to most of the technology and knowledge of its time and could flourish and expand. Information from the
Akhbār al-zamān, written between the late 10th to 11th century, states that Kanem by then was already a "vast and large" kingdom that was partly on the
Nile and at war with Nubians. Kanem transitioned into a true empire through expansion to the
Kaouar oases in the 11th century. Several archaeological sites have been identified in the oases, remains of former settlements, though they are yet to be excavated. It is believed that the northernmost settlements catered to travelers whereas the southern oasis settlements were focused on the salt trade. Through control of the trade routes to the north, the Kanem Empire exported ivory, slaves, and animal products. Foreign products, including weapons, books, beads, and cloth, were imported into the empire. In the 11th century, regulated taxation of the farmers around the capital at Njimi started to replace the previous patterns of nomad raiding and extortion. Increasing Islamisation of Kanem is evident from the 11th century onwards and Kanem had developed into a literate society by the 12th century, when the scribes of the empire are recorded to have developed an original script style, the
barnāwī.''''
In the 13th century, a ruler of Kanem is recorded to have gone on Hajj to Mecca. Shortly afterwards, the 13th-century mai
Dunama II Dibalemi is recorded to have "opened" the mune
, an important religious artefact of unclear nature. Dunama II brought Kanem to the zenith of its power. He commanded a cavalry of 40,000 horsemen and extended his rule as far as the Fezzan. Wars against the Sao, southwest of Lake Chad, were justified in the name of a jihad
, and captives were sold as slaves in exchange for further horses from North Africa. Pilgrimages to Mecca became a common occurrence, so much so that a hostel for pilgrims and students from Kanem was founded in Cairo. In 1257, the mai'' sent a giraffe as a gift to
Muhammad I al-Mustansir of the
Hafsid dynasty in
Ifriqiya. In the mid-13th century, Kanem ruled the
Fezzan as far as
Waddan.
Era of Instability (c. 1380–1472) spearman and a
Munga bowman, by
Edward Francis Finden (1826) In the 13th century, the
mais came into conflict with the
Bilala people, who lived within the empire. The
Bilala leaders may have been a
cadet branch of the Sayfawa dynasty. Conflict may have been motivated by the increased Islamisation alienating the more traditionalist Bilala. Kanem was at the same time becoming overstretched, suffering from pastures becoming overgrazed and dried out, lacking the natural resources required for a state of its size, and having become too dependent on the personal authority of the
mai. The
Medieval Warm Period also contributed to the drying up of Lake Chad, the heart of the empire. The empire began to be plagued by increasing internal and external conflict, as well as wars of succession. The 14th century saw the beginning of the so-called "Era of Instability", plagued by both internal and external conflict. In the 14th century, around the year 1380, the Bilala were able to oust the Sayfawa from power in Kanem and capture Njimi. Imperial control of the lands east of Lake Chad was terminated, and the Bilala would rule there independently until the 16th century. The rulers of the Bilala declared themselves
sultans, established a proper aristocracy, and posed a serious political alternative to the Sayfawa in the region surrounding Lake Chad.
Mamluk chancery manuals from the time accord the Bilala the same diplomatic status as the Sayfawa.
Mai Umar I Idrismi relocated across Lake Chad to Bornu in the west, a former tributary territory established in the 13th century. The Sayfawa quickly regrouped in Bornu, re-establishing a powerful kingdom there, and the
mais continued to rule as they had in Kanem. Intermarriages between the Kanembu people and the local Sao may have given rise to the modern-day
Kanuri people, who are often linked to the Kanem–Bornu Empire. The empire continued to be plagued by political instability in the form of repeated civil wars between descendants of
mai Dawud Nikalemi ("Dawudids") and
mai Idris I Nikalemi ("Idrisids"). Between about 1390 and 1470, no less than 15
mais occupied the throne, ruling in rapid succession. The civil wars impacted regions as far away from the imperial core as
Hausaland and
Darfur through economic upheaval and migrations of refugees. After the fall of Njimi, the empire lacked a permanent capital for about a century, with the court of the
mai constantly moving from one site to another. Very little information survives on the movements and locations of the
mais in this period. Prior to the foundation of the permanent capital of
Ngazargamu c. 1472, the
mai had apparently resided at a site called
Garu Kime for seven years and seven months. This site may correspond to modern-day
Monguno.
Modern period (1472–1893) Imperial apex (1472–1650) in the 15th century. The rise of the
Songhai Empire (yellow) was a considerable threat to Bornu (dark purple). Kanem (light purple) remained autonomous under the
Bilala but was reduced to a vassal state in the early 1500s.|left The Idrisid
mai Ali I Gaji emerged victorious from the civil wars of the 14th and 15th century. Adapting to the more urbanised society of Bornu, the empire became centered on a network of walled settlements that formed the core of its power. In c. 1472, Ali founded the empire's first substantial capital city,
Ngazargamu, on the shores of the
Yobe River. Ngazargamu served as a firm basis of political authority and was ideally positioned at the southern terminus of the trans-Saharan trade routes, and closer to emerging trade centers in Hausaland than previous capitals. The city became the focal point of the central
Sudan region for the next three centuries. After the foundation of Ngazargamu, some of the
mais went so far as to call themselves
caliphs. Indigenous practices and beliefs continued to persist even at this date, such as the
mai customarily appearing behind a veil or screen. The empire expanded in the 15th and 16th centuries. The
mais fought against various neighboring powers, such as the
Hausa city-states and
Kotoko principalities in the south and the
Wandala along the
Mandara Mountains. The most formidable enemy to arise in this period was the
Songhai Empire in the west, which competed for influence over Hausaland and sometimes raided Bornuan territory. Kanem itself was reconquered by Ali I's son
mai Idris III Katagarmabe in the early 1500s, though the center of the empire continued to remain in Bornu, probably because the area was more productive agriculturally and better suited to raise cattle. Idris sealed peace between the Sayfawa and Bilala through a diplomatic marriage and the Bilala were allowed to continue to govern Kanem as vassals. In the west, Idris III failed to conquer the
Kingdom of Kano but was recognised as the kingdom's suzerain and was paid tribute. By the reign of Idris III's son
mai Muhammad VI Aminami, the empire had fully regained its former prominence in the trans-Saharan trade. Through the political influence of Bornu, the
Kanuri language spread over a wide area.'
So-called Old Kanembu was also a prominent language, though reserved for Islamic scholarly studies.' The empire experienced some decline in the 1550s and 1560s due to famine and revolts against imperial suzerainty. In the 1570s, the threat posed by the Songhai Empire led
mai Idris IV Alooma to seek an alliance with the
Ottoman Empire. Bornu had been in contact with the Ottomans since the
Ottoman conquest of Tripoli (1551), and Ottoman mercenaries had been enlisted in various local conflicts. Prior to Alooma's reign, Ottoman firearms and tactical superiority had helped with conquests in the south and west of Bornu. Through diplomacy with Ottoman sultan
Murad III, Alooma secured Turkish muskets, as well as military training by Turkish instructors for the Bornuan army. Alooma was an ambitious ruler, who led several military campaigns and brought the empire to the height of its power. Although the actual territorial expansion of the state under Alooma was relatively minor, the subjugation of internal non-Muslim groups contributed to consolidating the state and long-distance diplomacy encouraged trade and cultural development. By the end of the 16th century, Bornu's sphere of influence extended from Hausaland to the Bahr el Ghazal River, and from south of Lake Chad to the Fezzan. The collapse of the Songhai Empire in 1591 and the decline of cities such as
Timbuktu and
Djenné made Bornu the new center of Islamic learning in central Africa, playing a crucial role in the local intellectual ecosystem. Alooma's reign was followed by a period of stabilisation in the early 17th century. Islam spread further into rural areas of the empire during this time and
Sufism experienced a surge in popularity.
Decline (1650–1807) The empire began to experience slow economic decline as early as the 15th century because of the increase in trade via the
Atlantic Ocean. In the 17th century, Bornu's control over the trans-Saharan trade was increasingly challenged. Ottoman officials in
Tripolitania periodically attempted to increase their own influence over the trade, sometimes creating agreements with Bornu and sometimes attempting to establish their own monopoly. The empire also came into conflict with the
Tuareg over control of the trans-Saharan trade routes. Under Tuareg pressure, the empire slowly lost the Kaouar oases and its control over the trade routes and was forced to establish defensive military outposts along its northern, western, and eastern borders. Several new neighboring states fought to increase their influence to the detriment of Bornu and imperial vassal states came under repeated attacks. In around 1630, The
Wadai Sultanate drove the Bilala out of Kanem, forcing the empire to militarily intervene in order to secure the eastern side of Lake Chad. The Bilala were forced to flee east, re-establishing themselves around
Lake Fitri. Bornu established new
buffer states in the north and west to protect against the growing power of Kano and the
Sultanate of Agadez. The imperial core was consolidated through the annexation of several frontier states, such as the Kotoko city-states. Despite military buildup, the empire abandoned certain military innovations. By the end of the 17th century, Bornuan armies had for instance ceased to use gunpowder weapons. Despite its declining power, the empire continued to be the main military power in the Chad Basin. The
Little Ice Age (16th–19th centuries) heavily impacted Lake Chad and the surrounding region, causing a drought while regions further south experienced increased fertility. Although Lake Chad reached its largest size since the 13th century, the lands surrounding the lake were rendered extremely dry, likely contributing to large-scale emigration of Bornuans. Trans-Saharan trade continued to be prosperous through the 17th century but new alternate trade roads were also established by powers such as the Hausa city-states and Wadai. Trade eventually decline to such a level that large empires could no longer be sustained, giving rise to smaller kingdoms and political chaos. Tuareg invasions and a famine in the latter half of the 17th century quickened the decline of the empire. Imperial expansion and military power stagnated in the 18th century. In the early 18th century,
mai Hamdan Dunamami repeatedly fought against the neighboring
Mandara Kingdom. A few decades later, under
mai Ali IV Kalirgima, the conflict with the Mandara Kingdom culminated in an 1781 invasion of Bornu and the defeat of the imperial army.
Fula jihads and the shehus (1807–1893) In the late 18th and early 19th century, a wave of Islamic revival swept through western and central Africa, partly motivated by competition between nomadic (largely
Fulani) and settled populations for land. From 1804 onwards, the religious leader
Usman dan Fodio began a series of military campaigns (the
Fula jihads), at first against the various states in Hausaland. The campaigns resulted in Usman being named
ʾAmīr al-Muʾminīn by his followers, and the establishment of the vast
Sokoto Caliphate. The rise of the Sokoto Caliphate shifted the cultural, economic, and political center of the region to the west and abruptly ended the traditional pre-eminent position of the Kanem–Bornu Empire. Due to internal strife, losses against Mandara, and perhaps a recent plague, Bornu was particularly vulnerable to attacks at the time. The
jihad had reached the empire by 1807. The Fulani denounced the people of Bornu as inadequate Muslims and captured most of the western provinces of the empire. In 1808, under
mai Ahmad Alimi, the Fulani captured and destroyed Ngazargamu. Much of the imperial core had by that time fallen into the hands of the invaders. In the same year, the local Islamic scholar
Muhammad al-Amin al-Kanemi was drawn into local conflicts with the Fulani in Bornu and managed to defeat some Fulani troops in the region of
Ngala. Al-Kanemi's victory garnered him the attention of the new
mai Dunama IX Lefiami, who summoned him to assist in the defense of the empire. Under al-Kanemi's leadership, the empire, despite its decline, proved strong enough to resist the Fulani invaders. Al-Kanemi received a large personal fiefdom, centered at
Ngurno, and organised a large slave-heavy cavalry army, supported by Kanembu spearmen and Arab light cavalry. He also led a propaganda campaign against the Fulani jihadists, questioning what right they had to wage holy war against Bornu. The Fulani were driven away from the empire and
mai Dunama was restored to power. Dunama briefly reoccupied what remained of Ngazargamu but soon abandoned the former capital in 1809 since it was too close to the Fulani frontier. To the ire of his people, Dunama retreated east but could not decide on a new site for a permanent capital, instead only spending a few months in any one given place. receives gifts from
Wilhelm I of the
German EmpireCourt intrigue, partly related to the great power awarded to al-Kanemi, led to Dunama being deposed by his courtiers in 1811, replaced with
mai Muhammad IX Ngileruma. Under Muhammad Ngileruma, a new imperial capital was established at
Kafela, close to al-Kanemi's seat at Ngurno. Al-Kanemi supported Dunama's restoration in 1814 but then began to act more independently. Al-Kanemi became the
de facto ruler of the empire and centralised power under himself. The
mai was continued to serve as a nominal ruler for a few decades. In 1814, al-Kanemi assumed the style of
shehu (
sheikh) and established a new seat,
Kukawa, which grew into one of the great metropolises of
sub-Saharan Africa. In 1817, Dunama plotted to eliminate al-Kanemi but was himself killed and replaced with the young puppet
mai Ibrahim IV Lefiami. At the death of al-Kanemi in 1837, he was succeeded as
shehu by his son
Umar Kura. Umar faced some resistance from both associates of his father and from the puppet
mai, but quickly took power. Ibrahim later tried to depose Umar through a civil war but was killed in 1846. Ibrahim was briefly succeeded by his son,
mai Ali V Minargema, who was also defeated and killed in battle. The thousand-year office of
mai came to an end and Umar and his successors assumed
de jure power over the empire, though still with the title of
shehu. Kafela was destroyed and Kukawa became the empire's formal capital. receives
Parfait-Louis Monteil at
KukawaBornu under the
shehus was substantially weaker than the state had been a few centuries earlier. Much of its former western territory remained under the Sokoto Caliphate and the state was cut off from the trans-Saharan trade in the north. The economic basis of the state had been further weakened by European pressure to end the slave trade. An economic crisis in Europe had also caused alternate export goods, such as ivory and ostrich feathers, to lose their value. By the 1850s, the army the empire was able to muster numbered about 10,000 cavalry (500 armored) and a larger number of infantry. These numbers were a sharp decline from the army fielded by al-Kanemi mere decades prior, which numbered 30,000 cavalry and 9,000 spearmen. Bornu became of interest to various European powers during the
Scramble for Africa. In treaties and agreements in the 1890s,
France and the
United Kingdom worked to designate "spheres of influence" in Africa. During this time, French and British representatives attempted to sign treaties with the
shehus of Bornu to eventually justify claims to the entire Bornuan territory in future negotiations. The French were particularly interested since they sought to link their existing colonies in
Senegal,
Algeria, and
Congo. In 1890, the
Royal Niger Company attempted to sign a treaty with
shehu Ashimi but their representatives were dismissed after spending two months in Kukawa. The
shehu then hoisted the flag of the Ottoman Empire as a symbol of his non-recognition of British authority.
Parfait-Louis Monteil eventually managed to secure diplomatic relations with Bornu on behalf of France in 1892. By the time the French attempted to make use of this relationship, Bornu had been captured by the Sudanese invader
Rabih az-Zubayr.
Fall of Kanem–Bornu (1893–1902) Rabih az-Zubayr's empire (1893–1900) in 1899|leftRabih az-Zubayr was a Sudanese adventurer and slave raider who entered Bornuan territory in 1892/1893. Rabih's forces captured
Karnak Logone, the capital of a small sultanate on the southeastern border of Bornu proper, and ejected the local population. With the fortified Karnak Logone as a base, Rabih could harvest resources from the vicinity and advance to
Amja, on the Bornu border.
Shehu Ashimi sent an army led by the experienced general
Momman Tahr against Rabih. Rabih defeated Tahr's army at the
battle of Amja, and Tahr was captured and executed. In August 1893, a
second battle took place at
Lekarawa, near Ngala. Rabih decisively defeated a Bornu army led by
shehu Ashimi and his nephew
Kyari. Ashimi and a few other survivors fled across the
Yobe River, abandoning Kukawa. Rabih spent some time at Kukawa but settled on
Dikwa as a capital, on account of its better communications and water supply. Rabih's takeover was opposed by the people of Bornu and most of the empire initially remained loyal to the al-Kanemi dynasty. A peasant revolt led by a man identified as
mallam Gantur managed to defeat one of Rabih's commanders before being put down. Shortly after the fall of Kukawa, Kyari seized power as the new
shehu and Ashimi was assassinated in the aftermath. Kyari faced Rabih in
battle on the banks of the Yobe River in February/March 1894. Rabih again emerged victorious and Kiyari was captured and executed. Kiyari's brother
Sanda Wuduroma made his way to southern Bornu, where he was proclaimed
shehu, but he was captured and executed after less than a month. Kukawa was plundered and burned, with its 120,000–200,000 inhabitants killed, enslaved, or dispersed. The death of Sanda Wuduroma left Rabih as the undisputed master of Bornu. The unprecedented conquest marked the first time the empire came under foreign domination. Geopolitically, Rabih largely behaved as his predecessors, working to maintain the borders of the empire and dominate the various lesser vassal states that surrounded the imperial core. His rule was however exceptionally brutal, marked by cruel punishments, heavy taxation, and an unprecedented concentration of power. Rabih established an autocratic state under himself as emir and a tiny military council (the
Zubat al-Kubar). Rabih's commanders transitioned into being the main holders of
fiefs in the empire. Those provincial rulers and courtiers who submitted to Rabih's forces were allowed to retain their holdings, albeit under close supervision of military commanders stationed at Dikwa. When local rulers became difficult to deal with, they were executed. In most cases, Rabih attempted to find replacements within their immediate families. Despite his brutality, Rabih's rule was in some ways also fairer and less corrupt than the aristocratic rule of the
shehus that had preceded him. Although taxation was heavy, the tax rate was also fixed and taxes were collected only once a year. Most of the state income was spent on the army and defense; Rabih did establish a palace at Dikwa, but little money was otherwise spent on personal luxuries, in stark contrast to the
shehus. Domestically, Rabih's greatest focus was on tax collection and supplies. Although highly efficient, the tax system was extortionate on the people and taxes were so heavy and brutally collected that it inspired revolts and migrations out of the empire. Revolts were met with brutal punishments; an 1896 uprising in
Nganzai led to the execution of over a hundred rebel leaders. Much of the money collected was spent on Rabih's palace and on the army. The plunder and mass displacement of people under Rabih, combined with the uncertainty created by the conquest, strongly impacted the Bornu economy, especially the agricultural sector. The state's formerly productive agricultural base was destroyed and Rabih was unable to revive it. Agriculture was further negatively affected by Rabih's army raiding villages for food, which fanned further unrest. Rabih's conquest of Bornu was a threat to the colonial boundaries and spheres of influence envisioned in negotiations between the United Kingdom, France, and the
German Empire. The British chose to recognise Rabih as a legitimate ruler of the empire, referring to him as the "Sultan of Borno". The French opted to deem Rabih illegitimate, since they could then justify conquests of parts of his empire. In 1899, Rabih had the French explorer
Ferdinand de Béhagle killed and France responded by
invading his empire. The French were easily able to recruit local allies in the war. Rabih was at first successful against the French under
Émile Gentil, but was eventually defeated and killed at the
battle of Kousséri (22 April 1900).
Al-Kanemi restoration (1900–1902) , the last ruler of the Kanem–Bornu Empire The death of Rabih created a power vacuum in the empire, paving the way for colonial occupation. Both the French and British worked to influence the struggles between the various claimants. By the time French forces came into contact with surviving princes of the al-Kanemi dynasty, the al-Kanemi forces had already regrouped under a recognised claimant,
Sanda Kura, son of the
shehu Ibrahim Kura. When the French reached Sanda Kura's forces, they agreed to recognise him as the new
shehu and he was invested as such by his followers on 14 January 1900. After Rabih's death at Kousséri, Rabih's son
Fadlallah collected his family and property at Dikwa and then retreated south with an army numbering 5,000, pursued by the French. Sanda Kura was installed as Bornu's new ruler at Dikwa. The French soon grew dissatisfied with Sanda Kura's governance. He was removed from office in July/August and deported to Congo in October. In his place at Dikwa, the French installed his more pliable brother
Abubakar Garbai as
shehu. French and British colonialism brought an end to the Kanem–Bornu Empire in 1902. Fadlallah tried to secure British support as ruler but his army was reached by French forces at
Gujba on 23 August 1901 and Fadlallah was killed in the ensuing battle. Although left without a figurehead, British forces occupied much of Bornu in March 1902, put under the
Northern Nigeria Protectorate. In 1902, Abubakar Garbai left Dikwa to become the figurehead
shehu of "British Borno". The circumstances of this is unclear; British colonial sources claim that he was invited and accepted the invitation, whereas German colonial sources from the same time claim that he was kidnapped by British troops. Abubakar Garbai left Dikwa in the care of
Sanda Mandarama, a brother of the former
shehu Kiyari and the city was occupied by the French in April 1902 and incorporated into
French Chad. Later in the same year, Dikwa was transferred to German control and became part of the German colony of
Kamerun. == Legacy and scholarship ==
