Atlantic slave trade The Atlantic slave trade or transatlantic slave trade involved the transportation by slave traders of enslaved African people, mainly from Africa to the Americas, and then their sale there. The slave trade used mainly the triangular trade route and its Middle Passage, and existed from the 16th to the 19th centuries. The vast majority of those who were enslaved and transported in the transatlantic slave trade were Africans from central and western Africa, who had been sold by other West Africans to Western European slave traders (with a small number being captured directly by the slave traders in coastal raids), who brought them to the Americas. The South Atlantic and Caribbean economies especially were dependent on the supply of secure labour for the production of commodity crops, making goods and clothing to sell in Europe. This was crucial to those western European countries which, in the late 17th and 18th centuries, were vying with each other to create overseas empires.
Saro (Nigeria) Saros or "Creoles in Nigeria" during the nineteenth century and early twentieth century were freed slaves who migrated to Nigeria in the beginning of the 1830s. They were known locally as saros (elided form of Sierra Leone, from the Yoruba "sàró") or Amaros: migrants from Brazil and Cuba. Saros and Amaros also settled in other West African countries such as the Gold Coast (Ghana). They were mostly freed and repatriated slaves from various West African and Latin American countries such as Sierra Leone, Brazil and Cuba. Liberated "returnee" Africans from Brazil were more commonly known as "Agudas", from the word "àgùdà" in the Yoruba language. Most of the Latin American returnees or Amaros started migrating to Africa after slavery was abolished on the continent while others from West Africa, or the Saros were recaptured and freed slaves already resident in Sierra Leone. Many of the returnees chose to return to Nigeria for cultural, missionary and economic reasons. Many (if not the greater majority) of them were originally descended from the Yoruba of western and central Nigeria. Other Nigerian groups forming part of the Sierra Leonean Krio population included Efik, Igbos, Hausa and Nupe.
