The British fully emancipated all slaves in 1838, and many freedmen chose to have subsistence farms rather than to work on plantations. Under British colonial rule Jamaica became a leading sugar exporter, with a plantation economy dependent on the African slaves and later their descendants. Named Santiago by the Spanish, the island remained a possession of Spain until 1655, when England (later Great Britain) conquered it, renaming it Jamaica. Many of the indigenous people either were killed or died of diseases, after which the Spanish brought large numbers of African slaves to Jamaica as labourers. Originally inhabited by the indigenous Taíno peoples, the island came under Spanish rule following the arrival of Christopher Columbus in 1494.
