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, contemporarily known as Rio Muni, was most likely predominantly inhibited 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-Cameroon: in 2002, ICJ ruled on an equidistance settlement of Cameroon-Equatorial Guinea-Nigeria maritime boundary in the Gulf of Guinea, but a dispute between Equatorial Guinea and Cameroon over an island at the mouth of the Ntem River and imprecisely defined maritime coordinates in the ICJ decision delayed final delimitation
