サハラ交易
The etymology of the name "Ghana" means "Strong Warrior King" and was the title accorded to the kings of the medieval Ghana Empire in West Africa, not to be confused with today's Ghana, as the empire was further north in modern-day Republic of Mali, Senegal, southern Mauritania, as well as in the region of Guinea. Ghana was known for its large Gold usage, and hence was named the "Land of Gold" by the Arabs during the Trans-Saharan trade.
