The Slave Coast is a historical name formerly used for parts of coastal West Africa along the Bight of Benin. The name is derived from the fact that it was a major source of African slaves during the Atlantic slave trade from the early 16th century to the 19th century. Other nearby coastal regions historically known by their prime colonial export are the Gold Coast, the Ivory Coast, and the Pepper Coast (or Grain Coast).
According to most research, the beginnings of the slave trade in this area are not well documented. It is difficult to track the development of trade in this area and its integration into the trans-Atlantic slave trade before about 1670, when European sources begin to document this trade.
The slave trade became so extensive in the 18th and 19th centuries that an “Atlantic community” was formed. The slave trade was facilitated on the European end by the Portuguese, the Dutch, the French and the British. Slaves went to the New World, mostly to Brazil and the Caribbean. Ports that exported these slaves from Africa include Ouidah, Lagos, Aného (Little Popo), Grand-Popo, Agoué, Jakin, Porto-Novo, and Badagry. These ports traded in slaves that were supplied by African communities, tribes and kingdoms, including the Alladah and Ouidah, which were later taken over by the Dahomey kingdom.
