Inhabited by Kalinago people since the 13th century, and prior to that by other Amerindians, Spanish navigators took possession of Barbados in the late 15th century and claimed for the Crown of Castile. It first appeared on a Spanish map in 1511. The Portuguese Empire claimed the island between 1532 and 1536, but later abandoned it in 1620 with their only remnants being an introduction of wild boars for a good supply of meat whenever the island was visited. An English ship, the ''Olive Blossom'', arrived in Barbados on 14 May 1625; its men took possession of the island in the name of King James I. In 1627, the first permanent settlers arrived from England, and Barbados became an English and later British colony. During this period, the colony operated on a plantation economy, relying on the labour of enslaved Africans who worked on the island's plantations. The slave trade to the island continued until it was outlawed by the Slave Trade Act 1807, with final emancipation of the enslaved population in Barbados occurring over a period of five years following the Slavery Abolition Act 1833.
