Cameroon

From the Sao of Lake Chad and the Bantu cradle of the Grassfields to a German colony, a divided trusteeship, and a bilingual republic still seeking its unity.

Cameroon's land holds one of Africa's deepest pasts. Near Lake Chad the Sao culture raised walled towns and cast striking terracotta and bronze, while the western Grassfields are widely held to be near the cradle from which Bantu-speaking peoples spread across central and southern Africa. Over centuries the region grew dense with states and societies: the trading Douala of the coast, the Grassfields kingdoms and fondoms — among them Bamum, whose King Njoya invented an original script — and, in the north, the Adamawa Emirate forged by the Fulani jihad of Modibo Adama. Portuguese sailors named the Wouri estuary the Rio dos Camaroes, the river of prawns, giving the country its name. From 1884 Germany ruled the protectorate of Kamerun until Allied forces conquered it in the First World War, after which the League of Nations split the territory between France and Britain. French Cameroun won independence on 1 January 1960 under Ahmadou Ahidjo, and in 1961 the British Southern Cameroons voted to join it, forming a federation reunified on 1 October 1961, while the British Northern Cameroons joined Nigeria. Since 1982 the country has been led by Paul Biya, and since 2016 the Anglophone regions have been gripped by a grave separatist crisis.

Independence of French Cameroun and reunification

1 January 1960

Modern Cameroon dates its sovereignty to 1 January 1960, when the United Nations trusteeship administered by France ended and French Cameroun became an independent republic under Ahmadou Ahidjo. The state took its present shape on 1 October 1961, when the formerly British-administered Southern Cameroons, having voted in a UN plebiscite to join rather than enter Nigeria, was reunified with the republic to form a federation. That founding rested on a far older world: the Sao towns of the Lake Chad basin, the Grassfields kingdoms such as Bamum and the Bamileke fondoms, the Fulani Adamawa Emirate of the north, and the Douala trading polities of the coast, all of which had been bound into the single colonial territory of German Kamerun from 1884 before its wartime partition between France and Britain.

Chapter 01 · c. 1000 BCE – 1600 CE

The Sao, the Bantu cradle and Cameroon's early peoples

Near Lake Chad the Sao raised walled towns and cast terracotta and bronze, while the western Grassfields are widely held to lie near the homeland from which Bantu-speaking peoples spread across a continent.

In the north, on the floodplains south of Lake Chad, the Sao culture flourished from roughly the sixth century BCE until as late as the sixteenth century CE. Building round, walled settlements along the Chari and Logone rivers, the Sao left elaborate terracotta figurines and cast-bronze ornaments that mark them as one of the earliest complex societies in the region. Their city-states reached their height between about the ninth and fifteenth centuries before being absorbed or displaced; several peoples of northern Cameroon and southern Chad, notably the Kotoko, trace their descent from them.

Far to the west, the grassy highlands straddling the modern Cameroon-Nigeria border carry a deeper claim still. Linguists and archaeologists widely regard this Grassfields zone as lying at or near the homeland of the Bantu languages, from which, beginning around 1000 BCE, Bantu-speaking farmers carried their tongues, crops, and iron-working east and south until they came to dominate most of central and southern Africa. The Bantu expansion is among the largest population and language movements in human history, and Cameroon sits close to its source.

Between these poles, the centuries that followed filled the land with varied societies: farmers and herders of the savanna, fishing and trading communities of the rivers and coast, and, in the fertile western highlands, the beginnings of the centralised chiefdoms that would later crystallise into the Grassfields kingdoms. Cameroon's extraordinary ethnic and linguistic diversity, often called 'Africa in miniature', has its roots in this long formative age.

The Grassfields of western Cameroon sit close to the cradle of the Bantu expansion, one of the largest movements of people and language in human history.

Chapter 02 · c. 1400 – 1884

Grassfields kingdoms, the Douala coast and the Fulani north

Portuguese sailors named the river of prawns; the Douala grew rich as coastal middlemen; the Grassfields fondoms and the kingdom of Bamum took shape; and the Fulani jihad forged the Adamawa Emirate in the north.

In the 1470s Portuguese mariners reached the estuary of the Wouri River and, struck by its swarming crustaceans, named it the Rio dos Camaroes — the river of prawns. From the Spanish and Portuguese form camarones came the later names Kamerun, Cameroun, and Cameroon. The coast they touched was home to the Douala, a people who from their towns around the estuary grew wealthy as middlemen, bartering palm oil, ivory, and other goods between European ships and the peoples of the interior under leaders the Europeans called kings, drawn from lineages such as Bell and Akwa.

In the western highlands, centralised kingdoms and fondoms flourished. The kingdom of Bamum, with its capital at Foumban, traces its dynasty to Nshare Yen in the late fourteenth century and grew through conquest and alliance into a powerful Grassfields state. Around it lay the many Bamileke fondoms — independent chiefdoms each ruled by a fon — whose densely organised societies remain central to Cameroon today. Bamum reached a celebrated height under King Ibrahim Njoya, who from the 1890s devised an original writing system, the Bamum script, and an associated court language, Shumom, an extraordinary intellectual achievement that recorded his kingdom's laws, history, and pharmacopoeia.

The far north was transformed by religious revolution. From about 1809 the Fulani scholar and warrior Modibo Adama, acting under the authority of Usman dan Fodio of the Sokoto Caliphate, led a jihad into the region of Fombina, founding the Adamawa Emirate. Governed from a capital that eventually settled at Yola, Adamawa became one of the largest and most complex emirates of the Sokoto Caliphate, spreading Islam and Fulani political authority across what is now northern Cameroon.

From the river of prawns came the country's name; from the palace of Foumban came one of Africa's few wholly indigenous writing systems.

Chapter 03 · 1884 – 1916

German Kamerun

A treaty with the Douala kings in 1884 opened three decades of German colonial rule, expansion into the interior, and forced labour, ended by Allied conquest in the First World War.

On 12 July 1884 the Douala kings Bell and Akwa, together with other coastal notables, signed a treaty of protection with German trading agents, and days later the explorer Gustav Nachtigal formally proclaimed a German protectorate over Kamerun. The Douala, long accustomed to controlling trade with the interior as middlemen, soon found their position undermined as Germany pushed to open direct routes inland; resistance and friction followed, but German power steadily advanced.

Over the following decades Germany expanded the colony far beyond the coast, subduing Grassfields and interior peoples in a series of campaigns, including the Bafut and Adamawa wars, and pressing into the Muslim north. In 1911, under the Treaty of Fez settling the Agadir crisis, France ceded a large territory known as Neukamerun, enlarging the colony to the east. German rule brought roads, plantations, and administrative order, but it rested heavily on coerced labour, harsh punishment, and the dispossession of communities such as the Douala, whose protests against land seizures around their estuary were met with repression.

The colony's German chapter ended in the First World War. From August 1914 British, French, and Belgian forces invaded Kamerun from several directions; after a long campaign through difficult terrain, the last German garrison surrendered in early 1916, and German officials and troops withdrew into neutral Spanish Guinea. The conquest brought three decades of German rule to a close and set the stage for the territory's partition.

German rule built plantations and roads on a foundation of coerced labour, until Allied armies conquered Kamerun during the First World War.

Chapter 04 · 1916 – 1959

Partition: French Cameroun and British Cameroons

The League of Nations split the territory between France and Britain; under their mandates and later UN trusteeships, a nationalist movement rose, and the suppression of the UPC turned into open war.

After the German defeat, the victorious Allies divided the former colony. The League of Nations confirmed the partition as mandates: France took the larger eastern portion as French Cameroun, while Britain administered two narrow western strips, the Northern and Southern Cameroons, governing them in close association with neighbouring Nigeria. After the Second World War both territories became United Nations trust territories, a status that committed the administering powers, at least in principle, to preparing them for self-government.

French rule developed plantations, railways, and a small educated elite, but it was authoritarian, and after the war an assertive nationalism emerged. In 1948 Ruben Um Nyobe and others founded the Union des Populations du Cameroun (UPC), which demanded immediate independence and reunification of the French and British territories. As the movement's popularity surged, the French administration banned the UPC in July 1955 after waves of unrest, driving it underground and into armed rebellion.

What followed was a long and brutal conflict, fought mainly in the Bassa and Bamileke regions, in which French and later Cameroonian forces waged a fierce campaign against the UPC insurgency. Ruben Um Nyobe was hunted down and killed by a French-led unit on 13 September 1958, and other UPC leaders were killed or driven into exile in the years that followed. The repression caused heavy loss of life and left deep and lasting scars, even as France moved the territory toward a negotiated independence.

The suppression of the UPC turned a nationalist movement into a guerrilla war, fought hardest in the Bassa and Bamileke country and remembered for its terrible cost.

Chapter 05 · 1960 – 1982

Independence, reunification and the Ahidjo years

French Cameroun became independent on 1 January 1960; in 1961 the British Southern Cameroons voted to join it while the north chose Nigeria, forming a federation under Ahmadou Ahidjo that hardened into a one-party state.

On 1 January 1960 the UN trusteeship over French Cameroun ended and the territory became an independent republic, the first step toward the modern state; Ahmadou Ahidjo, a Muslim politician from the north, became its first president. The British Cameroons faced a separate choice. In a UN-supervised plebiscite on 11 February 1961, the Northern Cameroons voted to join Nigeria, which it did on 1 June 1961, while the Southern Cameroons voted to reunite with the Republic of Cameroon.

Reunification took effect on 1 October 1961, when the Southern Cameroons joined the republic to form the Federal Republic of Cameroon, comprising a francophone East Cameroon and an anglophone West Cameroon. The Foumban Conference of July 1961, where the anglophone leader John Ngu Foncha negotiated the terms of union with Ahidjo, set the federation's framework. From the outset the new country joined a French-speaking majority with an English-speaking minority whose distinct legal, educational, and administrative traditions would prove a recurring fault line.

Ahidjo steadily concentrated power. In 1966 the country became a one-party state under his single national party, and in 1972 a referendum abolished the federation in favour of a centralised United Republic of Cameroon, dissolving West Cameroon's autonomy. The discovery and export of oil from the late 1970s brought new revenues. In November 1982 Ahidjo unexpectedly resigned, handing the presidency to his prime minister, Paul Biya.

Reunification on 1 October 1961 joined a French-speaking majority with an English-speaking minority — a union whose terms would be contested for generations.

Chapter 06 · 1982 – present

The Biya era and the Anglophone crisis

Paul Biya has held power since 1982 through one-party rule and tightly managed multiparty elections, while grievances over anglophone marginalisation hardened into an armed separatist conflict from 2016.

Paul Biya, a francophone Catholic from the south, became president in 1982 and consolidated his grip after surviving a failed coup attempt in 1984. Under international and domestic pressure, he legalised opposition parties in 1990 and held the first multiparty elections in 1992, which he won amid disputes over fairness. Constitutional changes in 2008 removed presidential term limits, and Biya has been repeatedly re-elected, most recently in October 2025 at the age of ninety-two, making him among the world's longest-serving and oldest heads of state; opposition leaders disputed the official results.

The reunification settlement left a lasting tension. Many in the two anglophone regions, the North-West and South-West, came to feel politically and culturally marginalised within a francophone-dominated state, with grievances focused on the imposition of French-trained officials in their English-based courts and schools. In late 2016 lawyers and teachers in those regions launched protests against these practices; a heavy security crackdown radicalised the movement.

By 2017 the protests had escalated into an armed conflict, as separatists proclaimed an independent state they called Ambazonia and took up arms against the government. The fighting has caused thousands of deaths and displaced hundreds of thousands of people, with abuses reported on all sides; government efforts such as a 2019 national dialogue and a grant of 'special status' to the regions have not ended the violence. Cameroon has meanwhile also faced spillover from the Boko Haram insurgency in its far north.

Grievances rooted in the 1961 union hardened, from 2016, into one of Africa's gravest separatist conflicts.
