Final answer:
The gold-salt trade played a significant role in the medieval West African economy and culture, involving the trade of gold and salt between kingdoms. Ghana, known as the 'land of gold,' was a central hub for this trade route. The Wangarans and Berbers were the key traders involved in the exchange of gold and salt.
Step-by-step explanation:
The gold-salt trade refers to the trading of gold and salt between the kingdoms in West Africa, particularly Ghana, during medieval times. Gold was abundant in the region of today's Ghana, while salt was obtained from salt mines in the Sahara desert. This trade route was important for the economic prosperity and wealth of Ghana and other African kingdoms, as well as for the dissemination of gold across North Africa and Europe.
The Wangarans were the merchants who traded gold, while the Berbers were responsible for trading salt. This trade route also attracted the attention of European powers, particularly the Portuguese, who were interested in gold and spices.
Overall, the gold-salt trade was a vital aspect of the economy and culture of West Africa during this period.
