Malabo (məˈlɑːboʊ , maˈlaβo; formerly Santa Isabel ˈsantajsaˈβel) is the capital of Equatorial Guinea and the province of Bioko Norte. It is located on the north coast of the island of Bioko (Etulá, and as Fernando Pó by the Europeans). In 2018, the city had a population of approximately 297,000 inhabitants. Spanish is the official language of the city and of the country as well, but Pichinglis is used as a language of wider communication across Bioko island, including Malabo. Malabo is the oldest city in Equatorial Guinea. Ciudad de la Paz is a planned community under construction in mainland Equatorial Guinea which was designed to replace Malabo as the capital. The institutions of governance of Equatorial Guinea began the process of locating to Ciudad de la Paz in February 2017. In 1472, in an attempt to find a new route to India, the Portuguese navigator Fernão do Pó, encountered the island of Bioko, which he called Formosa. Later, the island was named after its discoverer, Fernando Pó. At the beginning of the 16th century, specifically in 1507, the Portuguese Ramos de Esquivel made a first attempt at colonization on the island of Fernando Pó. He established a factory in Concepción (now Riaba) and developed plantations of sugarcane. With the treaties of San Ildefonso in 1777 and El Pardo in 1778, during the reign of the Spanish King Charles III, the Portuguese gave to the Spanish the islands of Fernando Pó, Annobón, and the right to conduct trade in the mainland, an area of influence of approximately 800 000 km2 in Africa, in exchange for the Colonia del Sacramento in Río de la Plata and the Santa Catarina Island off the Brazilian coast (occupied by the Spaniards). The area stretched from the Niger Delta to the mouth of Ogooué River — in current Gabon — and included, besides the islands of Fernando Pó and Annobón, the islets of Corisco and Elobeyes. Having failed its attempts to colonize these lands because they already had vast colonies in other parts of the world, Spain lost interest in Spanish Guinea in 1827 and authorized the British to use the island as a base for suppressing the slave trade.
