Pepper Coast was the name given by European traders to a coastal area of western Africa, between Cape Mesurado and Cape Palmas. It encloses the present republic of Liberia. It got its name from the melegueta pepper. The pepper is also known as the grain of paradise, which gave rise to an alternative name, the Grain Coast. The importance of the spice is shown by the designation of the area from the Saint John River (at present-day Buchanan) to Harper in Liberia as the "Grain Coast" in reference to the availability of grains of paradise. In some cases (as shown on the map) this term covers a wider area incorporating Sierra Leone and the Ivory Coast.
