Equatorial Guinea is the only sovereign nation in Africa where Spanish is an official language. This linguistic distinction is a direct consequence of a specific, centuries-long colonial history. The presence of Spanish today is a legacy rooted in 18th-century European treaties, solidified by deliberate colonial policy, and maintained by its continuing utility as a national language.
Transfer of Territory and Early Contact
The initial claim to the territory was established through a diplomatic exchange between European powers. Portugal, which had first explored the Gulf of Guinea coast and islands in the 15th century, ceded its rights to the islands of Annobón and Fernando Po (now Bioko), along with commercial rights to the mainland area to Spain. This transfer was formalized through the First Treaty of San Ildefonso in 1777 and the subsequent Treaty of El Pardo in 1778.
The treaties were primarily focused on resolving long-standing territorial disputes in South America, where Spain gave up claims to certain areas in Brazil in exchange for the African territories. Spain’s initial presence in its new African possession was sporadic, with early expeditions failing to establish a permanent administration. Spanish authority was not firmly reasserted until the mid-19th century, particularly from 1844 onward, as European powers began to consolidate their claims in the “Scramble for Africa”.
Spanish Rule and Linguistic Imposition
The widespread adoption of Spanish stems from the deliberate colonial policy of “Hispanization” pursued by the Spanish government. This policy sought the cultural assimilation of the indigenous population, with the Spanish language being the primary vehicle for this project. The colonial administration insisted on the exclusive use of Spanish for all official, legal, and governmental affairs, establishing it as the sole language of power and upward mobility.
The Catholic Church, particularly the Claretian missionaries, played a central part in this linguistic imposition by controlling the education system. Colonial education, often conducted in boarding schools, was designed to teach Spanish and Catholic doctrine, which were seen as inseparable components of civilization. This system ensured that a significant portion of the population, especially the elites, achieved a high degree of proficiency in Spanish.
Under the Francoist regime (1939-1968), the linguistic policy became more rigid, promoting Spanish as an instrument of a cohesive National-Catholic project. Speaking Spanish was equated with being a “good Spaniard,” and the language was prioritized over local languages like Fang, Bubi, and Ndowe. This consistent, long-term educational and administrative effort, which lasted until independence, ensured that Spanish was deeply embedded as the language of the modern state apparatus.
The Enduring Status of Spanish Today
Despite achieving independence in 1968, Spanish retained its position as the dominant language of the country. This was due to the high level of Spanish proficiency among the educated population at the time of independence, setting Equatorial Guinea apart from many other newly independent African nations. Spanish continues to function as the primary language of instruction in the national education system, from elementary schools through universities.
Spanish is the most widely understood lingua franca, serving as the language of communication between the country’s various ethnic groups. It remains the language used in government, the media, commerce, and other formal domains. While French and Portuguese were later adopted as co-official languages due to the nation’s geographic location, Spanish maintains a far greater presence and utility in daily life. More than 85% of the population speaks Spanish, which thrives alongside indigenous languages and local creoles such as Pichi on Bioko Island.
