The Ledger of Colonialism in Nigeria
How missionary schools, warrant chiefs, and forced taxation created modern Nigeria
This series became my longest because Nigeria is a tapestry of kingdoms, peoples, and collisions. In this piece on British Nigeria, I provide a recap, and then cover the southern resistance, indirect rule, the 1914 amalgamation, and the north–south divide.
I. The Big Recap
Part I gave an overview of Nigeria. Parts II & III traced the northern arc: the trans-Saharan slave routes, the rise of Middle Belt states such as Nupe, Borgu, Jukun, and Igala, the militarized Hausa city-states, the Kanem-Bornu empire, and the revolutionary jihad that forged the Sokoto Caliphate from the Hausa kingdoms.
The Letter That Started a War
When High Commissioner Frederick Lugard arrived with his threadbare army (3,000 African troops on a shoestring budget), he tried diplomacy first. The Sultan of Sokoto, Abdurrahman, replied in Arabic:
Lugard treated that as a declaration of war.
The conquest was swifter than expected. The Sokoto Caliphate was a patchwork bound by religious authority, not military unity. Each emirate kept its own forces and acted independently. From 1901 to 1903, ~300 British troops (mostly African soldiers) burned the emirates in Bida, Kontagora, and Zaria, liberating hundreds of slaves from the ruins. Then they stormed Kano and Sokoto. The Caliph Attahiru I was killed; Sokoto’s cavalry crumbled before British Maxim guns and artillery.
Lugard unilaterally installed Mohammed Attahiru II as a puppet sultan, bypassing Sokoto’s traditional elective council composed of clerics and emirs. At the ceremony, Lugard proclaimed:
In 1904, Bornu (once mighty, long hollowed out) fell without a fight. Britain then fixed northern Nigeria’s borders with France and Germany, leaving parts of old Sokoto and Bornu inside French Chad & Niger and German Cameroon.
The Southern Kingdoms
Part IV covers the southern polities in Igboland, Yorubaland, and Edoland, including Benin’s pepper and ivory trade and Warri’s slave trade with the Portuguese.
Part V follows how that trade metastasized to the Trans-Atlantic Slave Trade. Inland empires like Oyo raided and funneled captives to coastal middlemen kingdoms (Allada & Whydah), who exchanged human beings for cowrie shells, guns, cloth, and gunpowder with Europeans along the Bight of Benin. In the Bight of Biafra (Part VI), the pattern repeated with different players: the Aro network orchestrated raids across Igboland, selling captives to Ijaw and Efik canoe houses who ferried them to coastal cities (Bonny, Old Calabar, New Calabar) where European ships waited. There, the currency was brass manillas rather than cowries.
The Gradual Colonization
Part VII details Britain’s gradual conquest. First, the Royal Navy’s West African Squadron blockaded the coast to end the slave trade. Second, British merchants pivoted West African commerce toward palm oil and palm kernels. Third, quinine broke malaria’s grip on European explorers, opening the Niger River’s interior to missionaries and traders. By the 1840s, Britain established trade courts to settle disputes. By 1861, Britain annexed Lagos.
Part VIII introduced George Goldie, a British businessman who merged rival palm-oil trading companies and obtained a royal charter to make the Royal Niger Company. His firm monopolized trade along the Niger River and pushed inland with Maxim guns that murdered thousands. Eventually, Britain revoked his charter and reorganized the conquered territories. Lugard’s wife, Flora Shaw, then named these lands as “Nigeria.”
By then Britain administered three Nigerias: Southern Nigeria(Benin, Warri, Calabar, etc.), Northern Nigeria(Sokoto, Nupe, Kano), and the Lagos Protectorate (Lagos, Ibadan, Abeokuta), a mosaic with very different histories.
II. The Southern Resistance
The Southeast: Village by Village Conquest (1900-1919)
While the north fell swiftly to British firepower, southeast Nigeria (Igboland) was harder to subdue. The region was dominated by the Aro network, a commercial and religious group linking hundreds of acephalous Igbo villages through the Ibini Ukpabi shrine-cave at Arochukwu (the “Long Juju” as the British called it).
For over two centuries, the Aro had used this shrine-cave as both a court and a scam. Those found guilty supposedly disappeared into the cave, consumed by the deity according to cult officiants. In reality, they were led out a hidden back exit into slavery. The Aro sold thousands of Africans this way. The condemned criminals were sold to African middlemen in exchange for guns, making the Aro amass hard power in the region.
Some Igbo sub-groups, like the Obegu, signed protection treaties with the British, allowing missionaries to operate freely. As Christianity spread, it weakened the Igbos’ belief in the shrine-cave, since new converts no longer believed that a cave deity swallowed up criminals. When the Obegu openly rejected the cult, the Aro retaliated, raiding Ogebu villages and slaughtering 400 people. This gave the British its pretext to come guns-blazing.
In 1900, the British launched the Aro Expedition, mistaking the Aro trading network as a military confederacy. This miscalculation would cost them nearly two decades, as the expedition became a tiresome, village-by-village grind campaign. By recruiting their treaty Igbo/Ibibio allies like the Obegu, Asa, and Obokwe, the British burned Arochukwu and destroyed the shrine-cave.
Besides the Aro, other networks resisted. The Ekumeku secret societies waged guerrilla war from 1898 to 1911, forcing Britain to subdue villages with Maxim guns. Even neighboring peoples (the Okpoto, Urhobo, Isoko, and Ukwuani) fought the British right up to 1914. Control was declared in 1906, but pockets of resistance continued until 1919.
The conquest was also spiritual: oracles were outlawed, shrines destroyed, and Christianity advanced.
The Southwest(Yoruba): Creating Nationalism
In 1906, Lagos was merged into Southern Nigeria.
Two years later, protests erupted in the city over newly imposed water rates, led by an emerging class of educated Nigerians. Among them was Herbert Macaulay, grandson of the first Nigerian Bishop, Samuel Ajayi Crowther. Macaulay became known as the “father of Nigerian nationalism.”
By 1912, this ferment gave rise to the Southern Nigeria Civil Service Union, marking the beginning of organized political expression under colonial rule.
Before the 1920s, most Western educated Nigerians were “Saro”, ex-slaves or ex-slave descendants saved by Britain and shipped back to Sierra Leone before arriving home in Nigeria, like Macaulay. After 1920, the homegrown Nigerian elite grew. More Yoruba lawyers, clerks, and journalists educated in mission schools began to challenge British paternalism.
In 1920, National Congress of British West Africa was formed, and three years later the Clifford Constitution introduced limited elected African representation in colonial government from cities like Lagos. In 1925, Macaulay and other educated elites made newspapers like the Lagos Daily News and Daily Times to criticize colonial officials and explain government policy to a wider audience. The literate community spoke both to the educated elite and to the masses who still relied on word of mouth for news. By 1937, there were 50+ newspapers by 1937 in Ibadan, Abeokuta, Calabar, Port Harcourt and more.
III. Forging the Colonial State
Creating Tribalism
Before British rule, ethnic identity was fluid and local. Communities & families sometimes migrated due to droughts, slave raids, or wars, forcing people to adopt new identities and learn new languages or customs.
An African near the Niger River would identify themselves by their village, town, kingdom, or lineage rather than a “tribe”. For example, an African would most likely say “I’m from Oyo,” “I’m an Ife person,” or “I’m from Ijebu,” rather than say “My tribe is Yoruba.”
The British and missionaries changed that, though not entirely by design. Colonial officials wanted fixed categories they could govern, so they grouped loosely related peoples into large “tribes.” Missionaries, focused on evangelism, reinforced this by translating the Bible into a few written languages, collapsing many unwritten dialects into standardized forms. Once written, these languages gave educated Nigerian elites new shared identities and clear borders of belonging.
For example, “Yoruba”, comes from a Hausa-Fulani term. The Sultan of Sokoto, Mohammed Bello, used “Yarba” to describe the people in the old Oyo Empire. Missionaries and returnee slaves in Lagos and Freetown, Sierra Leone (people like Samuel Ajayi Crowther) transliterated Yarba to Yoruba and expanded that term to include nearby dialect groups (Ife, Ijebu, Abeokuta, Ilesha, Ibadan, & Ekiti) who spoke closely related tongues. In the process, the language of a once-mighty but hollowed-out rump kingdom became the basis for a new identity. The dialect of a fallen empire came to describe an entire group of people and their former vassals.
The same process created “Igbo,” a label for dozens of southeastern clans and hundreds of autonomous villages that spoke mutually intelligible dialects in Awka, Nri, Onitsha, Arochukwu, and more.
Mission schools and city life deepened these identities. Students learned standardized Edo, Yoruba, or Igbo, while migrants in cities formed hometown unions, welfare associations, and trade groups along ethnic lines.
By the early twentieth century, ethnicity had become a social reality. Groups such as the Society of Descendants of Oduduwa and the Igbo Descendants Union turned these new identities into political ones. What began as a colonial classification evolved into Nigeria’s proto-nationalism, organized around tribe. Britain then governed through these tribes where possible.
Indirect Rule in the North
In the Islamic north, emirs retained their titles but became paid agents of British district officers stationed at their courts. They still collected taxes, enforced Sharia, and administered justice, but rebellious emirs were deposed and replaced with loyalists. Christian missionaries were restricted to prevent religious conflict, as Lugard assured northern leaders that Britain would not interfere with their Islamic customs (except encouraging to end domestic African slavery). This left the north with minimal modern education or healthcare; if emirs wanted modern services, they had to fund the services themselves.
Indirect Rule in the Southwest
In Yorubaland, indirect rule fit existing hierarchies. The British kept the kings (Obas) and chief councils but made them accountable to colonial residents. Lagos, however, was treated differently. It was a Crown Colony, and its inhabitants theoretically had the same rights as British subjects. The Oba of Lagos became largely ceremonial while Governor William MacGregor and a legislative council ruled. Beyond Lagos, partly invented “native councils” enforced indirect rule. Resistant chiefs were fined or imprisoned.
Indirect Rule in the Southeast
The system worked in coastal/riverine towns like Calabar, Bonny, Degema, and Buguma, where the British could rely on long-established ruling houses from earlier 1850s trade relations.
In the hinterland, indirect rule was a disaster. The British could not find traditional rulers because most Igbo, Urhobo, and Ibibio villages were governed through councils, not kings. To fix this “problem,” the British created one. They invented “warrant chiefs,” often opportunists, outcasts, or outright criminals who lacked legitimacy. To many Igbos, they were simply thieves with British backing.
The historian A. E. Afigbo later described the tragic irony: When British officers demanded that communities “produce their chiefs,” many villagers assumed the British would execute or enslave them. To protect their village council, they presented marginal figures instead: criminals, debtors, or former slaves. The British then issued these men warrants and crowns, granting them unprecedented authority.
Answerable to colonial officers who made up new jurisdictions for chief rule, the warrant chief enforced direct taxation, labor conscription, cash-crop production targets, and forcibly replaced manilla brass currency with paper money. Resentment and uprisings followed.
IV. Stitching Nigeria with Rails, Roads, and Paper Money
Rail & Cash Crops
Between 1896 and 1912, Britain built two major railway lines: the Lagos–Kano through Ibadan and Ilorin, and the Port Harcourt–Enugu connecting the coast to the coalfields that powered the trains. These rails carried cocoa from Yorubaland, palm oil from the southeast, and peanuts, cotton, and rice from the north for export. Food production fell as farmers turned to cash crops, making Nigeria dependent on imported grain.
In Yorubaland, cocoa transformed rural life. Owning a cocoa farm became the key to wealth, pushing many families to lease or sell land. During WW1, when men were conscripted, Yoruba women dominated local markets in import-export trading. In Igboland, women managed cassava and yam production, building trading networks that fed towns and villages.
Nigeria’s export growth was massive (1904 to 1929):
There was barely any gold or diamonds, but tin in the Jos Plateau MiddleBelt attracted mining firms like Ropp Tin and Naraguta Company. However, the vast majority of Colonial Nigeria’s exports were agricultural.
Currency and Labor
In 1912, Britain replaced cowries and brass manillas with a colonial paper currency called the West African Currency Board. The new coins and paper money forced Nigerians into the cash economy. People now needed cash to pay taxes, which drove them into wage labor or cash-crop farming.
Infrastructure, Hobs, and Health
Britain expanded transport and sanitation for the export economy. Swamps were drained to curb malaria, ports were dredged, and roads connected farms to rail stations. Veterinary injections curbed diseases (i.e. sleeping sickness) in northern cattle. All of the manual labor was either:
Low-wage paid work: British firms or the colonial administrating hired Nigerians for mining, dock work, freight hauling, and more.
Corvée labore: The Brits also conscripted Nigerians against their will to build ports, roads, and railways. Many Nigerians fled these forced labor schemes by joining the military, turning to cash-crop farming, or migrating to cities where there was more paid labor (craftsmanship, tailoring, haircuts, trading, small businesses, and more).
Migration
Besides jobs, urban population growth was also driven by better healthcare. Lagos, the colony’s main port, expanded from 42K residents in 1901 to nearly 130K by 1931. The British made hospitals in the south, which lowered infant mortality and death rates while birthrates remained high, fueling city expansion.
The Dual Mandate
Britain made Nigeria a high-tariff zone with one exception: British goods. This was the “Dual Mandate” coined by Lugard. The UK could benefit from Nigerian cocoa, palm oil, and peanuts, while Nigerians could enjoy British manufactured goods like shirts, suits, pots, pans, and bicycles.
V. Amalgamation and the Taxation Crisis (1914-1929)
By the early 1910s, the Northern Protectorate was bankrupt, dependent on annual subsidies of nearly £300,000 from the more prosperous south and Britain. In 1914, Lugard merged the North & South into one Nigeria, despite protests from both regions.
This was done so the south’s customs revenue could finance the north.
World War I
Also in 1914 was WW1. From 1914 to 1918, thousands of Nigerian troops fought for the British Empire. The Nigeria Regiment of the West African Frontier Force joined troops from the Gold Coast (Ghana), Sierra Leone, and Gambia to invade the neighboring German colony of Cameroon.
The campaign was brutal. British and French forces advanced from multiple directions against the German African troops. Both sides scorched villages, burned crops, and starved civilians. The final German outpost in Cameroon surrendered in February 1916.
Some Nigerians also fought in the East Africa campaign. By 1918, when Lugard’s tenure ended, most chiefs were loyal to the British crown, though the king in Egbaland led an uprising before being subdued. After the war, Cameroon was divided between Britain and France.
The Taxation Crisis & The Woman’s War
In the north, taxation was familiar. Emirs had long collected taxes under the Sokoto Caliphate. In the south, however, direct taxes was alien. Colonial revenue came mainly from customs duties, court fees, and fines. In pre-colonial times, Yoruba rulers like the Alafin of Oyo or the Alake of Abeokuta never directly taxed their subjects.
Lugard insisted on introducing direct taxation in the south, claiming it would reduce government corruption, but his advisers warned it would provoke revolt. He went ahead anyway: Benin had direct taxes in 1914, Oyo in 1916, Abeokuta in 1918, and finally Igboland in 1926.
The backlash was fierce. In Abeokuta, women who refused to pay were stripped naked in public. In Egbaland, angry residents destroyed railways and telegraphs.
When direct taxes reached Igboland, the British started by taxing only men but soon considered including women. That rumor ignited one of the largest protests in colonial West Africa: the Aba Women’s War of 1929. Thousands of women marched from Owerri to Calabar, confronting British officers, burning native courts, and attacking the warrant chiefs’ homes. British troops fired on them, killing fifty-five women and ending the revolt.
The protest failed to end taxation but exposed the failures of the warrant chief system. In 1931-1932, Britain sent anthropologists to study Igbo governance, realizing a truth every Igbo villager already knew: traditional governance worked through clan and village councils, not kings.
VI. The North-South Divide
Education and Christianity in the South
Before colonialism, the Hausa, Fulani, and Kanuri in the north had been more literate than the southerners. By the 1500s, Quranic schools existed in the North, though literacy remained confined to a small male elite. Most southern societies, by contrast, lacked written language entirely, relying instead on oral traditions or pictographs like those in Igboland.
Christianity reversed that balance. Missionaries built schools that taught reading, writing, arithmetic, and scripture to southern boys and girls. Literacy spread rapidly, and mission schools gave local languages written form for the first time.
Mission schools produced southern Nigeria’s first literate, middle class, composed of teachers, clerks, merchants, doctors, and minor administrators. They built and maintained roads, electricity lines, telegraphs, and harbors that supported a growing export economy. They abandoned older customs such as slavery and polygamy and adopted Christian monogamy and European attire. A hat, a book, or a radio became a symbol of modern identity.
Yet Western education did not erase their Nigerian roots. Many retained their traditional names, spoke indigenous languages at home, and attended African-led churches where worship included drumming, dancing, and group baptism. These congregations blended Christianity with African rhythm and community, creating something distinct from European practice.
The mission-educated elite had the most to gain from colonialism, but also the most to resent. They filled the colonial clerical and teaching jobs, but they also saw the limits of that rule. For example, Nigerians were initially restricted to 4th grade education, Christian theology, or industrial training. It was hard to obtain more education. So, the literate middle class led early protests against racial exclusion and demanded political recognition for Africans.
By the 1920s, the southern literacy far outpaced the north. In 1921, there were 32K European-educated Southern Nigerians (0.5% of the population) and 4% had basic literacy.
By 1926, there were 18 secondary schools, though high fees restricted access. Only a handful of southern Nigerians attended university abroad in Sierra Leone or the UK, producing a small but influential class of doctors, lawyers, and engineers. Altogether, southern Nigeria had seventy-three post-university professionals, more than anywhere else in Sub-Saharan Africa at the time.
Southern education was almost entirely missionary funded(2K schools by 1921); the government invested little. Only a handful of government schools existed, mostly in the north. Northern Nigeria remained dominated by Quranic schools serving only wealthy boys. Northern enrollment in non-Quranic schools was less than 2% of southern levels.
The north also refused to educate girls. At best they learned Quranic verses from the Mallam, the learned man of the village. The Hausa believed that a literate woman would say to her husband “Why should I labor for you? I know more than you do” and leave him.
VII. Conclusion: The Ledger of Colonialism
We have barely discussed colonialism, but we can use this to answer the question: Was colonialism good or bad?
Clearly the slaughter with gatling guns to conquer people was grotesque and is indefensible. Burning towns and brutal pacification campaigns to subject millions to a rule they never asked for was heinous. Forced labor was terrible too, though a step up from slavery.
Yet the colonization that followed became an interesting test case for two experiments:
In the North, Britain preserved existing institutions. Emirs stayed in power, missionaries were restricted, and Islamic law continued. The result was social continuity but economic stagnation and backwardness.
In the South, Britain tore up the old order. Missionaries replaced shrines with schools, chiefs were invented, “backwards customs” were banned (i.e. murdering slaves & concubines to join their master in the afterlife and twin killings), and literacy, Christianity, and wage labor were introduced.
The outcome was stark. The region where culture was preserved remained poor and illiterate (except a small clerical & royal class, as since medieval times). The region where culture was uprooted became more educated, urban, and politically conscious.
Ironically, education was the perfect ingredient for nationalism. As the educated southern elites in Lagos, Ibadan, and other cities developed, they realized what the British restricted from them. The same mission schools that produced loyal clerks also produced critics who saw through Britain’s racial paternalism. Next time, we’ll talk about Nigeria during the Great Depression & WWII.
Needs a little editing. What's "morally wrought"? Of the colonialism choices, I'd say "all the above." Nigeria's story is like that of other nations, with pain, anguish, and some triumph. My experience is from the Biafran War, which hasn't entirely ended. Indirect rule in the North has given us Boko Haram. Good series, Yaw. I'll look forward to the next post.
also, I loved the article, keep it up bro!
