West and West-Central Africa were the regions that supplied the majority of the slaves taken across the Atlantic Ocean in all periods of the transatlantic slave trade. The image is of a map produced by Joan Blaeu in 1662. It shows the Atlantic coast of Africa stretching from Senegambia to Angola in West-Central Africa. This map was an important source of information for many cartographers and writers trying to better understand the continent and even today it offers important information for historians of Africa.
