The Remastered History of Nigeria Part III: The Rise & Ruin of the Sokoto Caliphate and Bornu
How a small group of religious devotees created an empire and got colonized and had how another empire try to reform but failed
Previously…
Part I traced Nigeria's foundations from 1000 BC to 1100 AD, introducing the Nok ironworkers, early Hausa settlements, the Kanem-Bornu Empire, and the Yoruba & Igbo heartlands.
Part II explored medieval northern Nigeria (1100-1700 AD), when Kanem-Bornu and the Hausa city-states became the commercial backbone of the Sahara trade network. They shipped slaves, kola nuts, and gold north to the Maghreb & Egypt while importing horses, steel weapons, and Ottoman firearms. Islam spread alongside trade, creating Africa's most literate societies outside the Nile Valley.

Why the Sokoto Caliphate arose within Hausa decline
How the region was ultimately conquered and folded into British Nigeria
18th Century : Reformers Rise, States Collapse
Seeds of Revolution
The 1700s were a period of upheaval in Hausaland and Bornu, marked by five intertwined crises:
Imperial Changes: Gobir emerged as the dominant Hausa power, expanding amid dynastic succession struggles that weakened Kebbi and Zamfara, conquering Kebbi and Zamfara during dynastic succession crises in the 1700s. Other Hausa states like Katsina claimed the remaining spoils.
Trade Reorientation: The trans-Atlantic slave trade overtook the older trans-Saharan routes. Hausa and Bornu merchants increasingly sold captives southward to Yoruba and Efik intermediaries at ports like Badagry and Old Calabar in exchange for firearms, textiles, beads, and cowries.
Religious Issues: Islam was widespread but shallow. Most rulers mixed Islamic law with older traditions such as spirit cults, divination, matrilineal inheritance, and local festivals. This provoked criticism from reformist clerics.
Corruption: Sultans like Kano’s Kumbari imposed sudden taxes or tax increases on grain and livestock, sold court appointments through bribery (“gaisuwa”), and enriched courtiers. The sarauta council system, an elective monarchy where nine grandees could choose or depose Hausa kings, became mired in patronage. Kings battled their own viceroys (Galadima) and treasurers (Ajiya) for control, while everyone demanded their cut.
Famine: Droughts & famines in the 1740s–50s caused grain shortages and riots. Islamic scholars blamed rulers for moral decay and neglect of the poor.
The Fulani Alternative
Amid this chaos, Fulani clerical families ( the Ulama) from Senegambia & Mali had quietly established Quranic schools in Hausa towns like Alkallawa and Degel. These Fulani scholars, both pastoralists and literate jurists, condemned Hausa corruption and offered a purer model of Islamic governance. Across the savanna, a wave of devoted Islamic clerics emerged in Nupe, Kano, Zaria, and Katsina.
One of the most prominent clerics was Shehu Uthman Dan Fodio, who called for tajdid (تجديد or Islamic renewal ).
The Inspiration: Futa Jallon & Turo
Dan Fodio drew inspiration from earlier Fulani jihads in Futa Toro (Senegal) and Futa Jallon (Guinea), where clerics had overthrown nominally Muslim rulers for straying from Sharia. Seeing himself as a mujaddid (renewer of faith), dan Fodio persuaded Gobir’s Sultan Bawa to roll back oppressive taxes, winning immense popular support.
Dan Fodio led the renewal movement in Hausaland. As Fulani polyglot scholar, he wrote extensively in Arabic and Fulani-Ajami on law, governance, and economics. Due to his intelligence, charisma, and oratory skills, he became profoundly convinced that Allah had chosen him as the mujaddid ( مجدد or renewer) for West Africa.
This created a fundamental tension. Traditionally, Kings relied on scholars for legitimacy, and scholars needed royal stipends to survive. But when dan Fodio’s movement gained mass appeal, the ruling elite turned on him.
Bornu's Parallel Decline
Meanwhile, the Kanem-Bornu Empire faced its own unraveling under Ali ibn Dunama (1742-1792). Bedde and Tuareg raiders seized slaves and vital salt mines from the west; Bagirmi armies struck from the east; internal pressures from large-scale migrations of Tubu, Kanembu, and Shuwa Arabs exacerbated grazing conflicts, causing famine from the center. Scholars accused Bornu rulers of mixing Islam with “pagan” customs, and tributary states stopped paying homage.
The moral vacuum across Hausaland and Bornu set the stage for a revolutionary religious war.
19th Century: The Rise of the Sokoto Caliphate
From Preacher to Commander
By 1800, Fulani Islamic reformers openly condemned Hausa corruption, a revolutionary break from traditional palace-aligned clerics. In response, in cities like Kano, Kings Sharif and Kumbari imposed new taxes and jailed scholars, fueling accusations of zalunci (injustice).
The Qadiriyya/Kâdirïyya Challenge
Dan Fodio's Torodbe family, part of a pan-Fulani clerical class, built a transethnic, literate network of Quranic schools, Ajami scribes, and Islamic judges. Funded by trade in manuscripts, ink, kola nuts, horses, and slaves, these scholars spread Islamic law across borders.
They continued to highlight the contradictions in Hausa Islam: Muslim rulers enslaved fellow Muslims, shrines and sacrifices to spirits persisted, and sharia law was ignored. From 1790-1802, dan Fodio traveled village to village across Hausaland, denouncing rulers' religious violations: oppressive taxes, disregard for Sharia, prohibition of Islamic dress (caps, turbans, veils), corrupt courts, and traditional idol worship. He urged Muslim communities to appoint independent judges, pay zakat to the Qadiriyya Sufi order, and stop paying tribute to rulers violating Sharia.
Initially, the reformers sought peaceful autonomy, founding self-governing communities on the fringes of Hausa states while negotiating exemptions from taxation and control over internal disputes.
The Point of No Return
As people and escaped slaves fled to these autonomous zones, local authorities watched their revenue and judicial power evaporate. Desperate rulers, like Sultan Bunu, attempted to reimpose control through force: raiding markets, confiscating livestock, and enslaving Fulani pastoralists.
This repression backfired spectacularly. Fulani herders, alienated by attacks on their communities and cattle, joined the reformers en masse, providing cavalry and manpower. More refugees fled to Qadiriyya settlements, hollowing out state authority.
In 1803, Yunfa ascended the throne of Gobir, restricted Fundamentalist Fulani religious preaching, ordered massacres of Fulani civilians, and attempted to kill Dan Fodio. This was ironic because dan Fodio taught Islam to Yunfa.
Dan Fodio fled from Gobir to Gudu and declared a hijra (migration), echoing the Prophet Muhammad’s flight from Mecca to Medina. Fulani clans rallied to his banner. In 1804, he was proclaimed Amir al-Mu’minin (Commander of the Faithful) of what Arabic sources called Dawlat al-Khilāfa fī Bilād al-Sudān—“the Caliphate in the Black Lands.” (The term “Sokoto Caliphate” is a modern shorthand, like “Byzantine Empire.”)
Uthman Dan Fodio and his Mujahedeen (Holy Warriors) declared jihad, launching the most successful Islamic revolution in West African history.
Lightning Conquest (1804-1809)
The jihad gained traction because many Hausa and Fulani saw dan Fodio not as a conqueror but as a purifier. Early campaigns relied on guerrilla tactics and intimate terrain knowledge, exploiting Hausa states weakened by famine and disease.
In October 1808, dan Fodio’s Mujahedeen killed Yunfa. By 1810, Gobir, Zamfara, Kebbi, Zaria, Katsina, and Kano had fallen. Look at the expanded Sokoto map below:
What had started as moral reform became empire.
Consolidation and Transformation (1809-1812)
Sokoto became the capital of a new empire stretching across northern Nigeria and into Cameroon and Chad. Despite his earlier purist stance, dan Fodio permitted some regulated cultural practices (like allowing festivals and music) to stabilize the transition. Former Hausa rulers could return under conditional loyalty oaths; resisters were exiled or replaced.
By 1812, the old Hausa political order was dismantled. The Fulani-led Caliphate now governed 31 emirates, forming West Africa’s largest centralized Islamic polity.
Dan Fodio ruled from Sokoto as the religious leader until 1815, when he retired from administrative duties. When dan Fodio died in 1817, his son Muhammad Bello became Caliph of Sokoto while his brother Abdullahi ruled the western provinces.
Bello, a skilled administrator, codified sharia governance, expanded schools and libraries, and established the kofa communication system, linking Sokoto with the provincial emirates. He also formalized the office of vizier (wazir) and divided the realm into four administrative quadrants: an early attempt at delegated provincial government.
Governance & Expansion
Many of the reforms that Dan Fodio rallied on were never implemented. Arbitrary cattle taxes continued (a tax Dan Fodio said was “non-Sharia compliant”) and enslaving Muslims continued and increased even though Sharia compliance was supposed to be enslaving of pagans. Still, Bello’s administration produced the most literate bureaucracy in sub-Saharan Africa, with judges, scribes, and tax officials active in every major emirate.
Militarily, the Caliphate lacked a standing army, relying instead on local levies led by each emir. Cavalry dominated warfare; firearms remained scarce until the late 1800s, mostly imported through Tripoli after selling slaves.
In terms of expansion, the Caliphate tried moving eastward, but it failed to conquer Bornu, leaving it as Sokoto’s main rival.
Here’s a zoom in of the territory the Caliphate had:
The Caliphate continued to press on South, swallowing up the Nupe and Igala in the mid 1820s.
Around this time in the 1820s, British explorer Hugh Clapperton became the first European to reach Sokoto, documenting the sophisticated Islamic state. Though he died of tropical disease in a subsequent visit in 1827, his journey highlighted the region's isolation from European influence, a protection that would soon erode with advancements in disease prophylactics.
Then by the late 1830s/early 1840s, the Emirates in the Sokoto Caliphate conquered parts of the Yoruba Oyo empire, specifically Ilorin, a frontier town at the edge of the empire. The Emirates pressed forward and sacked Oyo-Ile and took over other Yoruba towns.
By the mid 1840s, one of the Emirates of Sokoto conquered the Jukun.
Signs of Decline Amidst Conquest (1830s-1845s)
Despite conquering other polities, signs of decline emerged. Many Emirates rebelled, corruption spread, and Sharia courts lost credibility. After Bello's death in 1837, each successive Caliph faced succession disputes, emir disobedience, and regional rivalries. Famine in Kano and rebellions in Katsina and Nupe (1845–55) marked a transitional crisis as the founding generation of the Caliphate died.
The Unraveling
By the 1850s, Sokoto's centralized grip was loosening. Sokoto’s once-centralized system functioned mostly on paper. Caliphs continued to issue edicts and appointments, but distant emirs increasingly ignored the Caliph. To prevent hereditary dynasties from emerging, offices such as emir were rotated among rival lineages. This policy was meant to protect unity but which instead fueled dynastic feuds and civil wars, most notably the Kano crisis of 1893–95.
The Caliphate’s administrative machine, led by viziers, scribes, and tax officials, continued to function, but communication was painfully slow. A message from Sokoto to Bauchi or Adamawa could take weeks to arrive. Tribute collection and tax enforcement became inconsistent; much revenue never reached the capital.
By the mid-nineteenth century, Sokoto’s unity had eroded not only politically but ideologically. Competing Sufi orders, particularly the Tijaniyya, from Fez in Morocco, spread across the Sahel and across Hausaland, challenging Sokoto’s older Qadiriyya clerical elite. Scholars and provincial emirs increasingly wrote their own legal treatises and ignored central fatwas.
The Caliphate’s military relied on volunteer militias organized by individual emirs; no professional army or unified command existed. Horses and armored cavalry were still decisive, but their upkeep was expensive and firearms scarce. As military campaigns decreased, raiding became the main source of revenue, feeding an economy based on slave labor and tribute grain. The Sokoto continued the trans-Saharan slave trade, exporting 3,000–6,000 captives annually to North Africa.
Between the 1850s and 1880s, there was a brief economic boom among the merchant economy. Neighbors wanted Hausa-Fulani hides, leather, slaves and gold. As the merchant class was booming, Sokoto’s bureaucracy expanded.
The explosion of bureaucratic offices and dependents in Sokoto created what historians call a ‘bureaucratic inflation’: too many officials with too few revenues. Due to Sokoto’s increasing dysfunction, by the 1880s, millenarian talk of tajdid (renewal) re-emerged among scholars frustrated by corruption, a foreshadowing of later religious radicalism.
Emirates like Hadeija rebelled for over a decade, while Kano experienced a full civil war from 1893-1895 over royal succession.
Bornu
In the 1820s, Bornu resisted Sokoto imperialism under Shaykh Muhammad al-Kanemi.
After Sokoto’s attack, al-Kanemi made his polity undergo reforms. He reorganized taxation, curtailed hereditary chiefs, accepted Sharia, and established his own army of freed slaves and Kanembu cavalry.
His capital at Kukawa became a diplomatic hub linking North and West Africa. He maintained correspondence with the Ottoman Sultan and North African scholars, and even received British envoys like Hugh Clapperton and Dixon Denham. For a few decades, Bornu was a rival Islamic polity to Sokoto that combined bureaucracy with external diplomacy.
However, this revival ended when al-Kameni died and his son, Umar took over. Umar was a loser. He could not control the patronage system of local warlords and family rivals. The polity dissolved into civil war. Tuaregs raided from the northwest and invasions from Wadai from the east destroyed Bornu’s trade routes, while the he lost most of his tributary states.
By the 1860s, Bornu was hollowed out politically. The bureaucracy that al-Kameni built served competing nobles instead of Umar. Inflation soared, which in this case means barter goods and cowrie shells lost purchasing power. Grain and salt grew more expensive for Kanuri people as their grain and livestock lost real value. The treasury, once filed with millet, sorghum, beans, livestock, slaves, textiles, salt, and more, was no longer sufficient to maintain soldiers, horses, or the court.
The drought cycles between 1840-1860 also worsened the crisis. Famine and insecurity emptied farmlands as peasants fled raids and over-taxation of grain and cattle. Bornu’s officials, desperate for income, over-collected zakat (islamic tithe tax) and tribute, which deepened agricultural collapse. By the 1880s, Bornu barely existed. It was just clans taxing a starving population that they barely had any control over.
Bornu was finally toppled in 1893 by Rabih az-Zubayr, a Sudanese warlord. Rabih ruled briefly before being killed by French forces, after which Bornu’s remnants were gradually absorbed into British-controlled Northern Nigeria.
The collapse of Bornu, like Sokoto’s, was part of a wider Sahelian crisis. Caravan trade was declining and drought was returning. The Sahelian states were weak, ripe for colonial conquest.
20th Century
The Fall of Sokoto
By the late 1890s, the Sokoto Caliphate posed two problems for the British:
Territorial Competition: The Caliph claimed spiritual and political authority over Ilorin, Bida, and Yola—areas already under British control. This overlap threatened British legitimacy and risked rebellion.
Colonial Rivalry: France, already dominant in West Africa, had designs on Sokoto. In the Berlin Conference in 1885, the Europeans established the “Principle of Effective Occupation”, which meant that to claim territory, a European Power had to physically occupy it not just plant a flag or sign a treaty. British authorities feared being outflanked if France or Germany established a protectorate first.
By 1900, the Sokoto Caliphate was still the largest Islamic state in sub-Saharan Africa, with an estimated population of 10 million (about one-quarter of whom were enslaved). This made Sokoto the largest slave state on earth at the time. Slaves worked plantations, built infrastructure, or were sold to Arab-Berbers. On plantations, slaves produced for palm kernels, palm oil, and shea butter. New York Times did a whole article on slavery in that area.
However, slavery in Sokoto was complex: less racialized than in the Americas, yet in some cases more brutal, as forced castration was practiced. Some slaves gained property or eventual freedom. Regardless, Sokoto’s slave economy furnished Britain’s imperial excuse for “civilizing conquest.”
The British Advance
To assert control, the Royal Niger Company attempted to establish a post and a British Resident in Sokoto in 1899, but the Caliph rebuffed the offer.
British Colonial Secretary Joseph Chamberlain now openly advocated war:
On January 1st, 1900, the Royal Niger Company was dissolved. The British government absorbed its territories and reorganized them into three administrative zones:
Lagos in the southwest
Southern Nigeria covering everyone from the Bight of Biafra to to the Bight of Benin (Benin, Warri, Yoruba of Lagos, Ibadan, Oyo, Ijaw, different Igbo clans, and more.)
Northern Nigeria, which at the time covered the Muslim Middlebelt: Nupe, Ilorin, Bida). Britain claimed Sokoto and the wider north, but these were cartographic fictions. They were lines on maps, not authority on the ground yet.
Frederick Lugard, appointed High Commissioner , was a career imperialist with experience in India, Hong Kong, Egypt, Uganda, and Nyasaland(Malawi), where he expelled Arab slave traders. He had already created the West African Frontier Force to counter French expansion in Borgu. Now he commanded 3,000 African troops with a shoestring budget, operating from Lokoja, an outpost on the Middle Niger where he hoisted the Union flag.
Lugard first attempted diplomacy with the Sokoto Caliphate, requesting an end to slave raiding. But, the Caliph, Atiku, rejected all British overtures.
In an Arabic letter to Frederick Lugard, the Caliph wrote:
Lugard treated that letter as a declaration of war. The conquest was easier than expected since the Caliphate wasn’t truly united; each emirate maintained its own forces and fought independently.
Between 1901–1902, 300 British troops (mainly African) burned Bida, Kontagora, and Zaria, freeing hundreds of enslaved captives. In 1903, they stormed Kano and Sokoto itself. The Caliph Attahiru I was killed; the empire’s famed cavalry crumbled before British Maxim guns and artillery.
Lugard unilaterally installed Mohammed Attahiru II as a puppet sultan, bypassing Sokoto’s traditional council of electors, scholars, emirs, and descendants of the first Caliph. At the ceremony, Lugard proclaimed:
In 1904, Britain took Bornu without even fighting (it was a shell of its former self). The borders of Northern Nigeria were finalized. However, Islamic resistance continued well after the borders were finalized. For example in 1906, the Hausa Emir of Hadeija launched a final uprising that spilled into French Niger, forcing France and Britain to cooperate to tranquilize the Emirate of Hadeija.
Lugard recognized a practical problem: with so few British personnel and limited funds, direct rule was impossible. His solution, borrowed from British India and later adopted across British Africa, was indirect rule. Indirect rule meant governing through existing emirs and sultans as long as they abandoned slavery and cooperated with British officials. Islam and the emirate structure thus survived, stripped of sovereignty. Next time, in part IV, we’ll delve into Southern Nigeria, discussing the Benin Kingdom, the Igbo, the Yoruba, and the Trans-Atlantic Slave trade.
Concluding thoughts
Northern Nigeria’s story is one of irony. The Sokoto Caliphate began as a reformist revolt against corrupt rulers, only to reproduce hierarchy and slavery on an even larger scale. Its literacy, bureaucracy, and legal system made it one of Africa’s most sophisticated states, yet these same institutions eased British control once the Caliphate fell.
Pre-colonial and post-colonial Nigeria echo each other: entrenched patronage, moral disillusionment, and populist revolt. The Sokoto reformers sought justice through faith; today’s extremist insurgencies (ISWAP & Boko Haram) claim the same lineage but reject Sokoto’s legacy of scholarship and education. Also, ISWAP and Boko Haram kidnap, suicide bomb, and kill people indiscriminately.
Ironically, northern Nigeria was once more literate and urbanized than the south. Colonial education reversed that balance, the south embraced Western schooling while the north, wary of missionaries, resisted it.
