  1. 1Ethiopian unification: Tewodros II, Yohannes IV, Menelik II
  2. 2The Mahdist state in Sudan
  3. 3Case studies: Samori, the Ndebele and the Niger Delta states

By 1850, Ethiopia was not one country. Three rulers, one after another, rebuilt it into a strong, unified, independent state.

From division to independence

  • Before: a patchwork of rival regional lords fighting for power
  • Ethiopians call this period the Zemene Mesafint — the 'Era of the Princes'
  • After: the only African power to defeat a European invasion and keep its independence through the whole colonial period
1

Tewodros II (r. 1855–1868)

Born a minor noble, he fought his way to the throne and declared himself Negusa Nagast — 'King of Kings'. He crushed rival warlords one by one, built a modern army with local blacksmiths casting cannon, and tried to end the power of regional princes so the emperor, not the nobles, ran the country. He also tried to modernise the church and reduce its landholding, which made him enemies among the clergy.

2

Yohannes IV (r. 1872–1889)

Took over after Tewodros died fighting the British at Magdala (1868) and a period of renewed civil war. Yohannes ruled as a genuine King of Kings — letting regional rulers (like the future Menelik in Shewa) keep local power as long as they accepted his overall authority. This compromise held the empire together. He also defended Ethiopia from Egyptian invasion and Mahdist raids from Sudan, dying in battle against the Mahdists at Metemma in 1889.

3

Menelik II (r. 1889–1913)

King of Shewa who became emperor after Yohannes died. He nearly doubled Ethiopia's territory through conquest of the south and west (Oromo, Sidama and other regions), bought modern rifles and artillery from European rivals playing them off against each other, and used this modernised army to smash an invading Italian force at Adwa in 1896 — the event that forced Italy to recognise Ethiopian independence.

Tewodros unified by force, Yohannes unified by compromise, Menelik unified by expansion and won at Adwa.

Why this matters for the exam: The three emperors solved the SAME problem — a fragmented country with no central authority — using three DIFFERENT methods: military force, negotiated overlordship, and territorial expansion backed by modern weapons. A strong essay always compares their methods, not just their dates.

The Treaty of Wuchale (1889) deserves a special mention. Menelik signed it with Italy, but the Amharic and Italian versions disagreed about whether Ethiopia had become an Italian protectorate. Menelik rejected the Italian claim, Italy invaded to enforce it, and the result was the Battle of Adwa (1 March 1896) — a decisive Ethiopian victory using rifles, artillery and superior local knowledge of terrain against roughly 20,000 Italian troops.

  • Zemene Mesafint — the 'Era of the Princes', decades of civil war before Tewodros
  • Negusa Nagast — 'King of Kings', the traditional Ethiopian imperial title claimed by all three
  • Battle of Magdala (1868) — British expedition defeats and kills Tewodros II
  • Battle of Metemma (1889) — Yohannes IV dies fighting Mahdist forces from Sudan
  • Battle of Adwa (1896) — Menelik II defeats Italy, securing recognised independence

In 1881, a religious teacher called Muhammad Ahmad declared himself the Mahdi. He stepped into deep Sudanese discontent with Egyptian rule.

Why many Sudanese were discontented (1870s–1880s)

  • Sudan was ruled by Egypt, itself under growing British influence
  • High taxes
  • Corrupt officials
  • Attempts to stop the local slave trade
What 'Mahdi' means: In Islamic tradition, the Mahdi is a divinely guided redeemer figure, expected to restore justice before the end of times.
  • Religious appeal — the Mahdi called for a return to strict Islamic practice and rejection of foreign (Turco-Egyptian) rule
  • Economic grievances — heavy taxation and Egyptian mismanagement of Sudan's economy
  • Resentment of anti-slavery policy — Egyptian/British efforts to restrict the slave trade angered slave-trading elites who became Mahdist allies
  • Weak Egyptian control — Egypt itself was financially and militarily overstretched, unable to respond effectively

The Mahdi's forces, known as the Ansar, won a string of victories, culminating in the capture of Khartoum in January 1885 after a long siege — during which the British governor-general, General Charles Gordon, was killed. This humiliated Britain and made the Mahdist state a fully independent power controlling most of Sudan.

The Mahdi dies, the state survives: Muhammad Ahmad died of typhus only months after taking Khartoum, in June 1885. Power passed to his chosen successor, the Khalifa Abdallahi ibn Muhammad, who ruled the Mahdist state until 1898 — proving the state was institutional, not just built around one charismatic leader.
FeatureUnder the Mahdi (1881–85)Under the Khalifa (1885–98)
Basis of rulePersonal religious authorityInherited religious title + military control
Main achievementConquest of Khartoum, unification of resistanceConsolidating administration, defending borders
Key conflictWar against Egypt/BritainWar against Ethiopia (Yohannes IV, 1889) and eventually Anglo-Egyptian reconquest

The Mahdist state eventually fell to an Anglo-Egyptian force under Kitchener at the Battle of Omdurman (1898) — but that reconquest belongs to the colonial period, so for THIS section focus on how and why the state rose and how it functioned independently for over a decade.

Alongside the named states, essays let you choose two case studies of state-building. This lesson gives you two strong, contrasting ones, plus the Niger Delta trading states, which you need to know in their own right.

Three kinds of state-builder

  • A West African military empire built by conquest
  • A Southern African kingdom built by a breakaway warrior group during the Mfecane
  • Two Niger Delta trading states, Opobo and the Itsekiri, built on control of the palm-oil trade

Samori Toure and the Mandinka Empire

Samori Toure began as a trader and small-scale soldier in the 1850s in the region of modern-day Guinea/Mali. From the 1860s he built a personal army through conquest and alliance, eventually declaring himself Almami (Islamic ruler) and creating the Mandinka Empire (also called the Wassoulou Empire), which by the 1880s covered a huge area of the West African savanna.

  • Professional standing army — the sofa, well-drilled infantry and cavalry, unusual for the region at the time
  • Local weapons production — Samori set up workshops that copied and repaired European rifles, reducing dependence on outside supply
  • Administrative reorganisation — the empire was divided into provinces under appointed governors answering to Samori
  • Use of Islam — Islam gave the empire shared law and legitimacy, though Samori ruled pragmatically rather than purely religiously
  • Scorched-earth strategy — when forced to retreat from French pressure in the 1890s, Samori relocated his entire empire eastward rather than surrender
Why the Mandinka Empire matters: Samori shows that African state-builders could match European military technology through local adaptation, not just imitation — his rifle workshops and standing army were genuine innovations, not simply copies.

The Ndebele kingdom under Mzilikazi and Lobengula

Mzilikazi had been a commander under Shaka Zulu but broke away around 1823 after a dispute, leading his followers north during the chaos of the Mfecane. After years of migration and fighting, he settled his people — now known as the Ndebele (Matabele) — in what is today south-western Zimbabwe by the late 1830s, building a kingdom on Zulu-style military and social organisation: an age-regiment (amabutho) army system and cattle-based wealth.

1

Mzilikazi (r. c1823–1868)

Founded the kingdom through migration and conquest, imposing Zulu-derived military organisation on the peoples he absorbed, and established the capital region around Bulawayo.

2

Lobengula (r. 1870–1894)

Mzilikazi's son and successor, who maintained the kingdom's strength and independence through skilled diplomacy with European visitors and neighbouring African states, granting and revoking mining concessions to play outsiders against each other — though this ultimately could not stop British encroachment after his death.

Mzilikazi built the Ndebele kingdom by breaking away and migrating; Lobengula defended it by playing outsiders off each other.

Same toolkit, two kingdoms: Both Shaka's Zulu (from the previous micro) and Mzilikazi's Ndebele used the same amabutho age-regiment system — because Mzilikazi had served under Shaka. This is a strong comparative point for essays on the spread of Zulu-style state-building.

The Niger Delta trading states: Jaja and Nana

In the Niger Delta (south-eastern Nigeria), states rose through trade, not conquest. Once Britain banned the slave trade, Delta merchants switched to palm oil, which British factories needed for soap, candles and machine grease.

How the palm-oil trade worked

  • Producers — farmers in the interior (Igbo and Urhobo lands) made the oil
  • Middlemen — Delta trading houses carried it down the creeks in large canoes and sold it on the coast
  • European firms — British traders bought it on the coast, paying in cloth, guns, salt and spirits
  • The source of power — whoever controlled the creeks to the inland markets controlled the profit

Jaja of Opobo (c1821–1891)

1

From slave to trading chief

Jaja was born in Igboland and sold as a slave to Bonny, the leading Delta port. He rose through the Anna Pepple trading house and became its head in 1863.

2

Founding Opobo (1869)

After a civil war in Bonny, Jaja led his followers to a new site at the mouth of the Imo River and founded Opobo. It sat between Bonny and the inland oil markets, so he could cut his rivals off. Britain recognised him as King of Opobo in 1873.

3

Defending the monopoly

Jaja would not let British firms trade directly with the inland producers, and he began shipping oil to Britain himself. When he signed a British protection treaty in 1884, he had the free-trade clause taken out.

4

Removed by trickery (1887)

Consul Harry Johnston invited Jaja aboard a British gunboat with a promise of safe conduct, then arrested him. He was tried in Accra and exiled to the West Indies, and died in 1891 on his way home.

Nana Olomu of the Itsekiri (c1852–1916)

1

Governor of the Benin River (1884)

Nana led the Itsekiri trade on the Benin River, and Britain recognised him as its governor in 1884. From his fortified town of Ebrohimi he controlled the palm-oil trade with the Urhobo hinterland.

2

Clash with the protectorate (1890s)

Nana also signed a protection treaty in 1884. But British officials of the new Oil Rivers (later Niger Coast) Protectorate wanted open trade with the interior, and accused Nana of blocking the markets.

3

The fall of Ebrohimi (1894)

British naval forces attacked Ebrohimi and took it in September 1894 after a hard siege. Nana surrendered, was tried and exiled to the Gold Coast, and was allowed home only in 1906.

Resistance or collaboration? Both: Jaja and Nana signed treaties and traded with Britain, yet both fought to keep control of the trade. Use them to show that many rulers collaborated on their own terms, and resisted when Britain threatened their economic independence.
The limit of a trading state: Samori built power on an army, Mzilikazi on regiments, Jaja and Nana on control of trade routes. Once Britain wanted direct access to the interior, a middleman state had no force able to stop its gunboats.
