▸Era −1Traditional Rulers — the pre-colonial polities (pre-1879)

10 heads

Before the Royal Niger Company, before the consuls, and centuries before the Crown, executive authority over the territory now called Nigeria was exercised by sovereign African polities — the Sokoto Caliphate, the Borno Empire, the Oyo Empire, the Benin Kingdom, the Aro Confederacy, the city-state kings of the Niger Delta and the Yoruba obas of the south-west. Each was overlaid (not abolished) by a specific charter company, consul or governor between 1879 and 1903, and most of these thrones are still extant today. Match the entries below to the charter entries in Era 0 to see which Briton took over which throne. For the full chieftaincy register and through-line table, see Kingdoms & Monarchies in each State of the Federation.

1.c. 1180 (Oranmiyan / Eweka I) — 18 February 1897 (sack of Benin)

Oba of Benin · Benin Kingdom

One of the oldest continuously reigning dynasties in Africa. Overlaid by: Sir Ralph Moor, High Commissioner of the Niger Coast Protectorate, via the February 1897 Benin Punitive Expedition. Throne restored in 1914 under Eweka II. Monetary context: the Punitive Expedition's seizure of ~4,000 Benin Bronzes was a direct capital extraction from a kingdom that had refused to convert from pre-sterling pricing — see How the currency fell before the flag.

Oba Ovonramwen deposed and deported to Calabar after Sir Ralph Moor's Benin Punitive Expedition, 18 February 1897. Royal bronzes looted.

2.c. 1300 (founding at Oyo-Ile) — 3 February 1893 (Carter Treaty)

Alaafin of Oyo · Oyo Empire

The greatest pre-colonial Yoruba state — its cavalry empire stretched from the Niger to the Volta at peak. Overlaid by: Sir Gilbert Carter, Governor of Lagos, via the 1893 Carter Treaties that ended the Kiriji War and converted the Alaafin from sovereign to salaried agent of indirect rule.

After the Kiriji War (1877–1893), Alaafin Adeyemi I signed the Carter Treaty of 3 February 1893 placing Oyo under British protection

3.c. 9th c. (Saifawa dynasty) — 1902 (British conquest)

Shehu of Borno · Kanem–Borno Empire

Among the longest continuously ruling dynasties on earth — the Saifawa kings of Kanem–Borno reigned for almost a thousand years. Overlaid by: Lugard's WAFF (Borno 1902), in coordination with French and German forces converging on Rabih's short-lived warlord state.

Rabih az-Zubayr sacks Kukawa (1893); French defeat Rabih at Kousséri (April 1900); British WAFF occupies Borno in 1902 and restores the al-Kanemi line under Shehu Bukar Garbai at the new capital Yerwa-Maiduguri

4.c. 1430 (founding) — 20 May 1892 (Anglo-Ijebu War)

Awujale of Ijebu-Ode · Ijebu Kingdom

The Ijebu blockade of the interior trade routes was the immediate trigger for the 1892 British conquest of Yorubaland. Overlaid by: Sir Gilbert Carter, Governor of Lagos (Anglo-Ijebu War, May 1892).

Ijebu cavalry defeated at Imagbon by Col. Francis Scott's Maxim-armed column, 20 May 1892; trade routes opened by force

5.c. 1600 (Efik settlement at Creek Town/Duke Town) — 10 September 1884 (Hewett Treaty)

Obong of Calabar · Efik city-states

The Atlantic-facing Efik city-states of Old Calabar dominated the Cross River slave and palm-oil trade for two centuries. Overlaid by: Edward Hyde Hewett (10 September 1884 Treaty) and the Oil Rivers Protectorate consular system. Monetary context: the Efik trading houses ran one of the largest cowrie-and-copper-rod credit networks on the West African coast through the Ekpe society. The Zanzibar cowrie dump (1845–70s) and the protectorate's sterling-tariff regime wiped out the houses' working capital. See How the currency fell before the flag.

Treaty of Protection signed with Edward Hewett, 10 September 1884; Calabar becomes the consular headquarters of the Oil Rivers Protectorate (1891)

6.c. 1690 (founding by Akuma & Nnachi) — 28 December 1901 (Long Juju destroyed)

Eze Aro · Aro Confederacy

The hegemonic non-state network of Igboland — the Aro ran the inland slave trade and a continent-spanning oracular court through the Ibini Ukpabi shrine. Overlaid by: Sir Ralph Moor (Aro Expedition, December 1901 – February 1902). Monetary context: Arochukwu was also the largest interior cowrie-credit clearinghouse in the Bight of Biafra. The British crash of cowrie purchasing power (over 80% between 1851 and 1869) left the Aro factor-houses structurally bankrupt before Festing's 1,500-man force arrived. See How the currency fell before the flag.

Aro Field Force destroys the Ibini Ukpabi ('Long Juju') oracle, 28 December 1901; confederacy administrative network broken by 1902

7.1804 (jihad of Usman dan Fodio) — 15 March 1903 (fall of Sokoto)

Sultan of Sokoto · Sokoto Caliphate

The largest African empire of the 19th century — 30 emirates from Adamawa to Ilorin, an estimated population of 10–20 million. Overlaid by: Sir George Goldie (1897 Bida–Ilorin expedition) and Sir Frederick Lugard (1900–1903 northern conquest). The Sultanate continues to this day as Nigeria's pre-eminent Muslim throne.

Conquered by Lugard's WAFF; Caliph Attahiru I killed at the Battle of Burmi, 27 July 1903. Throne preserved under indirect rule.

8.1869 (founding of Opobo) — 19 September 1887 (deportation)

King Jaja of Opobo · Opobo Kingdom

The greatest of the Niger Delta merchant princes — a former Igbo slave who became Africa's richest palm-oil king. Overlaid by: Edward Hyde Hewett (Treaty of Protection 1884) → Acting Consul Harry Johnston, who deported him in 1887 in defiance of the protection treaty's trade clauses. Monetary context: Opobo was founded in 1869 precisely to escape the cowrie- and manilla-rigged Bonny market and trade palm-oil directly for sterling with Liverpool firms — the one currency the British were not actively crashing. See How the currency fell before the flag.

Tricked aboard HMS Goshawk by Acting Consul Harry Johnston on 19 September 1887; deported to the West Indies and St Vincent; died en route home in 1891 off the Canary Islands

9.1883 — 1894 (deportation)

Nana Olomu · Itsekiri Kingdom

Itsekiri merchant-prince and headman of the Benin River palm-oil trade. Overlaid by: Sir Claude MacDonald, Consul-General of the Oil Rivers Protectorate, via the 1894 Ebrohimi Expedition. Monetary context: Nana's working capital was denominated in cowries and manillas — currencies the British had crashed by flooding the coast with Zanzibar ring cowries from the 1840s. The 1894 charge of 'refusing to open Itsekiri markets to British firms' was, at base, a charge of refusing sterling conversion. See How the currency fell before the flag.

Ebrohimi sacked by MacDonald's Niger Coast Constabulary, September 1894; Nana tried at Calabar and deported to Accra (1894–1906)

10.1889 — 1898 (exile and death)

King Koko Mingi VIII · Nembe Kingdom

The Ijaw king whose 1895 raid on Akassa broke the Royal Niger Company's commercial sovereignty. Overlaid by: the Royal Niger Company (Goldie) — but the raid triggered the 1896 Kirk parliamentary inquiry that led to the revocation of the RNC charter on 31 December 1899. Monetary context: the Akassa Raid was a direct revolt against the RNC's sterling-tariff monopoly, which had cut Nembe's cowrie- and manilla-based houses off from their upriver palm-oil hinterland. See How the currency fell before the flag.

After the 29 January 1895 Akassa raid on RNC headquarters, Rear-Admiral Bedford burned Nembe and Brass; Koko fled into the creeks and died in exile at Etiema in 1898

▸Era 0Charter Companies & Protectorate Consuls (1879 — 1899)

5 heads

Before there was a 'Nigeria' there was the Royal Niger Company. Sir George Taubman Goldie's merged firm extracted treaties at gunpoint along the Niger from 1879, governed as a chartered company from 1886, and sold its sovereignty to the Crown on 1 January 1900. In parallel the Oil Rivers / Niger Coast Protectorate consuls (Hewett, MacDonald, Moor) administered the Delta and East. This is where colonial Nigeria actually began.

1.1879 — 1899 (RNC chartered 10 July 1886)

Sir George Taubman Goldie

The architect of British Nigeria. Goldie's Royal Niger Company signed (and where necessary coerced) the treaties along the Lower and Middle Niger between 1884 and 1892 that gave Britain its claim at the Berlin Conference. The 1897 Bida–Ilorin expedition under Maj. Arnold and the constant gunboat patrols of the Niger flotilla were his work. Without Goldie there would have been no Nigeria.

Charter revoked 31 Dec 1899; RNC territories transferred to the Crown on 1 January 1900 for £865,000 in compensation

Sir Gilbert Thomas Carter

The single most consequential British figure in Yoruba history. Carter led the 1892 Ijebu Expedition that broke the Ijebu blockade, signed the 1893 Carter Treaties that ended the 16-year Yoruba civil wars (Kiriji War) and inaugurated indirect rule over Yorubaland, and built Carter Bridge connecting Lagos Island to the mainland (1901, posthumously).
