Slave ships, often called Slavers and Guineamen, were ships which were used to transport black slaves from Africa to the Americas. Some of them were built for the purpose, while other were converted to carry slaves.
Only a few decades after the discovery of America by Europeans, demand for cheap labor to work plantations made slave-trading a profitable business. The peak time of slave ships to the Atlantic passage was between the 17th and 18th century when large plantations developed in the English colonies of North America. The most significant routes of the slave ships led from the north-western and western coasts of Africa to South America and the south-east coast of North America and the Caribbean.
