Middle Africa (1840–1851 CE): European Encroachment, Wadai's Expansion, and Anti-Slavery Initiatives

Between 1840 and 1851 CE, Middle Africa—encompassing modern Chad, Cameroon, Central African Republic, Equatorial Guinea, São Tomé and Príncipe, Gabon, Republic of the Congo, Democratic Republic of the Congo (DRC), and Angola including its Cabinda enclave—witnesses expanding European influence, increasing anti-slavery activities, and continued power struggles among local kingdoms, especially in the region around modern-day Chad.

French Establishment in Gabon

France consolidates its territorial ambitions along the coast of modern Gabon, establishing formal protectorates through treaties with Gabonese coastal chiefs in 1839 and 1841. In 1842, American missionaries from New England establish a mission at the mouth of the Komo River, signaling deeper Western engagement with local populations.

In 1849, French authorities capture an illegal slave vessel and free the enslaved Africans aboard. These liberated captives establish a settlement near the mission station, naming it Libreville (meaning "free town"). This symbolic act highlights France’s increasing involvement in anti-slavery operations while laying foundations for further French colonial expansion in Gabon.

Wadai’s Expansion and Military Strength

The Sultanate of Wadai, located northeast of the Sultanate of Bagirmi, continues to strengthen significantly during this era. Originally a non-Muslim state emerging in the sixteenth century as an offshoot of Darfur (in modern western Sudan), Wadai had converted to Islam early in the seventeenth century under the leadership of Abd al-Karim, who had overthrown the ruling Tunjur group. By the early nineteenth century, Wadai, under Sultan Sabun (r. 1804–c.1815), had expanded its power, establishing prosperous trade routes northward via Ennedi, Al Kufrah, and Benghazi, minting its own coinage, and importing military advisers, firearms, and armor from North Africa.

In 1838, political instability due to a disputed succession invites interference from Darfur, which seeks to install its preferred candidate, Muhammad Sharif, on Wadai’s throne. Sharif, however, rejects Darfur’s interference and decisively asserts his own authority. Rapidly consolidating his power, Sharif becomes one of Wadai’s strongest and most capable rulers. Under his rule, Wadai’s military campaigns extend westward into the territory of Kanem-Borno, eventually establishing Wadai’s hegemony over the Sultanate of Bagirmi and kingdoms as far away as the Chari River.

Notably, while in Mecca, Sharif had met the founder of the influential Senussi Islamic brotherhood, a movement especially prominent in Cyrenaica (in present-day Libya). This connection provides Wadai with a powerful ideological basis for resistance to later French colonization, making the sultanate a potent regional force into the twentieth century.

British-Spanish Relations and Anti-Slavery Efforts on Fernando Pó

During this period, the island of Fernando Pó (modern Bioko, part of Equatorial Guinea) becomes the focus of European anti-slavery initiatives. In 1827, Britain had moved the headquarters of the Mixed Commission for the Suppression of Slave Traffic to Fernando Pó without official Spanish consent, leasing a base at Malabo to assist British naval patrols combating the Atlantic slave trade. Due to economic and political pressures, Spain had found it profitable to lease the territory to Britain, especially as Spain’s earlier abolition of slavery in 1817 had reduced the colony’s economic attractiveness.

An effort by Spain to sell Fernando Pó outright to Britain in 1841 fails due to intense opposition from Spanish parliamentarians and public opinion. Consequently, in 1844, Britain formally restores Fernando Pó to Spanish sovereignty, and the island becomes officially known as part of the Territorios Españoles del Golfo de Guinea ("Spanish Territories of the Gulf of Guinea"). Despite returning Fernando Pó, British influence in the region continues strongly, illustrated by the actions of Governor John Beecroft, who uses the island as a launching point for the British seizure of Lagos—the first significant British territorial acquisition in what will become Nigeria.

Legacy of the Era

The period between 1840 and 1851 thus witnesses intensified European intervention in Middle Africa, driven by anti-slavery motives and imperial ambitions. The establishment of Libreville symbolizes an emerging colonial infrastructure, while Wadai’s aggressive military expansion under Muhammad Sharif sets the stage for later confrontations with European colonizers. Simultaneously, the strategic and diplomatic maneuverings over Fernando Pó underscore European rivalries and shifting colonial alliances that significantly shape the region’s political landscape in subsequent decades.
