Which religion was introduced to ghana through the gold-salt trade? christianity islam judaism animism

The introduction of Islam developed during the 600's and 700's through the gold-salt trade routes. The West African Empires (Ghana, Mali, Songhai) traded gold with the Arab and Berber merchants who brought salt from the Sahara region and manufactured goods from the northern Mediterranean ports. Those merchants and missionaries who came to Ghana, brought with them their religion, Islam. As a result, rulers in Ghana adopted Islam. Besides, Ghana kings decided to hire Muslim advisors to help them rule because they believed that Muslims were very intelligent  people.

The religion that was introduced to Ghana through the gold-salt trade is Islam.

The comercial transactions between the northern region of Africa and  the western region, such as the gold-salt trade, led to Islamism being disseminated through the African continent. In Ghana particularly, the acceptance of the Islamic religion began with the conversion of traders in the 11th century.
