Anguilla was first settled by Amerindian tribes who migrated from South America. The earliest Amerindian artefacts found on Anguilla have been dated to around 1300 BC, and remains of settlements date from 600 AD.[1] The date of European discovery is uncertain: some sources claim that Columbus sighted the island in 1493, while others state that the island was first discovered by the French in 1564 or 1565.[2] The name Anguilla derives from the word for "eel" in any of various Romance languages (modern Spanish: anguila; French: anguille; Italian: anguilla), probably chosen because of the island's eel-like shape.
Anguilla was first colonised by English settlers from Saint Kitts, beginning in 1650. Other early arrivals included Europeans from Antigua and Barbados. It is likely that some of these early Europeans brought enslaved Africans with them. Historians confirm that African slaves lived in the region in the early seventeenth century. For example, Africans from Senegal lived in St. Christopher (today St. Kitts) in 1626. By 1672 a slave depot existed on the island of Nevis, serving the Leeward Islands. While the time of African arrival in Anguilla is difficult to place precisely, archive evidence indicates a substantial African presence (at least 100) on the island by 1683.
The island was administered by England, and later the United Kingdom, until the early nineteenth century when – against the wishes of the inhabitants – it was incorporated into a single British dependency along with Saint Kitts and Nevis. After two rebellions in 1967 and 1969 and brief period as a self-declared independent republic headed by Ronald Webster, British rule was fully restored in 1969. Anguilla became a separate British dependency (now termed a British overseas territory) in 1980.
Anguilla is an internally self-governing overseas territory of the United Kingdom. Its politics takes place in a framework of a parliamentary representative democratic dependency, whereby the Chief Minister is the head of government, and of a pluriform multi-party system.
The United Nations Committee on Decolonisation includes Anguilla on the United Nations list of Non-Self-Governing Territories. The territory's constitution is Anguilla Constitutional Order 1 April 1982 (amended 1990). Executive power is exercised by the government. Legislative power is vested in both the government and the House of Assembly. The Judiciary is independent of the executive and the legislature. Military defence is the responsibility of the United Kingdom.
