Seychelles (, ; ), officially the Republic of Seychelles (; Creole: La Repiblik Sesel), is an archipelagic state consisting of 115 islands in the Indian Ocean. Its capital and largest city, Victoria, is east of mainland Africa. Nearby island countries and territories include the Comoros, Madagascar, Mauritius, and the French overseas departments of Mayotte and Réunion to the south; and Maldives and the Chagos Archipelago (administered by the United Kingdom as the British Indian Ocean Territory) to the east. It is the least populated sovereign African country, with an estimated 2020 population of 98,462. Seychelles was uninhabited prior to being encountered by Europeans in the 16th century. It faced competing French and British interests until coming under full British control in the late 18th century. Since proclaiming independence from the United Kingdom in 1976, it has developed from a largely agricultural society to a market-based diversified economy, characterized by rapidly rising service, public sector, and tourism activities. From 1976 to 2015, nominal GDP grew nearly 700%, and purchasing power parity nearly 1600%. Since the late 2010s, the government has taken steps to encourage foreign investment. As of the early 21st century, Seychelles has the highest nominal per capita GDP of any African nation. It has the second-highest Human Development Index of any African country after Mauritius. It is the only African country classified as a high-income economy by the World Bank. Seychellois culture and society is an eclectic mix of French, British, and African influences, with more recent infusions of Chinese and Indian elements. The country is a member of the United Nations, the African Union, the Southern African Development Community, and the Commonwealth of Nations. History Seychelles was uninhabited until the 18th century when Europeans arrived with enslaved Africans. It remained a British colony from 1814 until its independence in 1976. Seychelles have never been inhabited by indigenous people, but its islanders maintain their own Creole heritage. Early history Seychelles was uninhabited throughout most of recorded history. Tombs on the island, visible until 1910, are the basis for the scholarly belief that Austronesian seafarers and later Maldivian and Arab traders were the first to visit the archipelago. Vasco da Gama and his 4th Portuguese India Armada discovered the Seychelles on 15 March 1503; the first sighting was made by Thomé Lopes aboard Rui Mendes de Brito. Da Gama's ships passed close to an elevated island, probably Silhouette Island, and
