Which was the main cause of the development of the Swahili culture

The main cause of the development of the Swahili culture was the Indian Ocean trade. This trade network connected the East African coast with the Middle East, India, and even China, leading to the exchange of goods, ideas, and cultural practices. The Swahili people, who were a mix of African, Arab, Persian, and Indian influences, developed a unique culture that blended elements from these different regions. This included language, religion, architecture, and cuisine, among other aspects. The Swahili coast became a hub for trade and cultural exchange, leading to the growth and development of the Swahili culture.
