Cultural Blending on the Swahili Coast
The cultural blending on the Swahili coast was instrumental in making it an ideal region for exchange. Due to the intermingling of Arab and Bantu cultures, a unique and shared language known as Swahili emerged, allowing for efficient communication in trade. This blending, along with a common religion of Islam, united the people and facilitated a vibrant exchange of goods, including luxury items, between the East and the peoples of Africa. Products from the African interior, such as gold and ivory, were traded for goods from Arabia, Persia, India, Southeast Asia, and China.
