evidence: Equatorial Guinea consists of a continental territory and five inhabited islands; it is one of the smallest countries by area and population in Africa. The mainland region was most likely predominantly inhabited by Pygmy ethnic groups prior to the migration of various Bantu-speaking ethnic groups around the second millennium BC. The island of Bioko, the largest of Equatorial Guinea’s five inhabited islands and the location of the country’s capital of Malabo, has been occupied since at least 1000 B.C. In the early 1470s, Portuguese explorers landed on Bioko Island, and Portugal soon after established control of the island and other areas of modern Equatorial Guinea. In 1778, Portugal ceded its colonial hold over present-day Equatorial Guinea to Spain in the Treaty of El Pardo. The borders of modern-day Equatorial Guinea would evolve between 1778 and 1968 as the area remained under European colonial rule. [...] Equatorial Guinea is one of the smallest and least populated countries in continental Africa and is the only independent African country where Spanish is an official language. Despite a boom in oil production in the 1990s, authoritarianism, corruption, and resource mismanagement have concentrated the benefits among a small elite. These practices have perpetuated income inequality and unbalanced development, such as low public spending on education and health care. Unemployment remains problematic because the oil-dominated economy employs a small labor force dependent on skilled foreign workers. The agricultural sector, Equatorial Guinea’s main employer, continues to deteriorate because of a lack of investment and the migration of rural workers to urban areas. About two-thirds of the population lives below the poverty line as of 2020.
