Guinea is named after the Guinea region. Guinea is a traditional name for the region of Africa that lies along the Gulf of Guinea. It stretches north through the forested tropical regions and ends at the Sahel. The English term Guinea comes directly from the Portuguese word ''Guiné'', which emerged in the mid-15th century to refer to the lands inhabited by the ''Guineus'', a generic term for the black African peoples south of the Senegal River, in contrast to the "tawny" Zenaga Berbers above it, whom they called ''Azenegues'' or Moors.
