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.
Scottish trade in the Middle Ages Scottish trade in the Middle Ages includes all forms of economic exchange in the modern boundaries of Scotland and between that region with outside locations, between the departure of the Romans from Britain in the fifth century and the establishment of the Renaissance in the early sixteenth century. There are not the detailed custom accounts for most of the period that exist for England, that can provide an understanding of foreign trade. In the early Middle Ages the rise of Christianity meant that wine and precious metals were imported for use in religious rites. Imported goods found in archaeological sites of the period include ceramics and glass, while many sites indicate iron and precious metal working. The slave trade was also important and in the Irish Sea it may have been stimulated by the arrival of the Vikings from the late eighth century.
