Cameroon holds 27.9 million people as of 2023 estimates, distributed across territory that compresses West African savanna, Central African rainforest, and Atlantic coastline into 475,442 square kilometers. The country contains over 250 distinct ethnic groups speaking approximately 280 living languages, making it among the most linguistically diverse nations globally. The Bamiléké and Bamoun peoples dominate the western highlands around Bafoussam and Foumban. The Fulani populate the northern regions from Garoua to Maroua. The Duala established coastal trading networks around what became Douala centuries before European contact. The Beti-Pahuin group, including Ewondo and Bulu subgroups, concentrate in the south central zone around Yaoundé. English and French both hold official status, a direct artifact of the colonial partition, with approximately 20 percent of the population using English primarily in the Northwest and Southwest regions and 80 percent using French. Cameroon Pidgin English serves as a lingua franca across Anglophone areas and increasingly in mixed urban settings.
The Portuguese reached the Wouri River estuary in 1472, naming it Rio dos Camarões after the abundance of shrimp they found. German colonial administration began in 1884 after Gustav Nachtigal signed treaties with coastal Duala chiefs, establishing Kamerun as a protectorate that lasted until 1916. The Germans built railway lines from Douala toward the interior, introduced plantation agriculture for cocoa and rubber, and executed King Rudolph Douala Manga Bell in 1914 for opposing forced relocation policies. World War I brought Franco-British military campaigns that expelled German forces by 1916. The League of Nations partitioned the territory in 1919, awarding roughly four-fifths to France as Cameroun and one-fifth to Britain, which administered its portion as two non-contiguous zones attached to Nigeria. French Cameroun achieved independence on January 1, 1960, under Ahmadou Ahidjo. The southern portion of British Cameroons voted in a February 1961 UN plebiscite to join the francophone state, creating the Federal Republic of Cameroon on October 1, 1961. The northern portion of British Cameroons joined Nigeria. Ahidjo consolidated power through single-party rule under the Cameroon National Union, suppressing the leftist Union des Populations du Cameroun, whose leader Ruben Um Nyobé was killed by French forces in 1958 during the pre-independence insurgency.
Paul Biya assumed the presidency on November 6, 1982, after Ahidjo's resignation, and has held the office continuously across multiple constitutional amendments that eliminated term limits. The country maintains a unitary republic structure since the 1972 referendum abolished federalism. Serious Anglophone grievances intensified from 2016 onward when lawyers and teachers in the Northwest and Southwest regions protested perceived marginalization and the imposition of francophone legal and educational systems. These protests evolved into armed separatist activity by groups seeking independence for an entity called Ambazonia, producing displacement and violence that persists as of this writing. The conflict has created internal displacement affecting hundreds of thousands, with specific casualty figures remaining contested and difficult to verify independently. Cameroon experienced a limnic eruption at Lake Nyos on August 21, 1986, when carbon dioxide suddenly released from the crater lake suffocated approximately 1,746 people in surrounding valleys, one of the deadliest natural disasters in African recorded history.
Sultan Ibrahim Njoya of the Bamoun kingdom created the Bamum script between 1896 and 1918, developing it through multiple stages from an initial 1,000 pictographic characters to a refined 80-character syllabary. The script represents one of fewer than twenty writing systems invented in human history without external model influence. Njoya also documented Bamoun customs and history, established schools teaching the script, and built the Foumban Royal Palace, which now houses a museum containing manuscripts, thrones, and royal regalia. The palace remains an active sultanate seat. The Bamiléké chiefdoms of the western highlands maintain traditional governance structures where fons hold authority over complex secret societies. These societies use carved masks and elaborate beadwork during ceremonies marking agricultural cycles and succession rituals. The Bamiléké produce distinctive architecture featuring wooden pillars carved with human and animal figures supporting thatched roofs.
