Where Africans or Muslim Traders on the Swahili coast first?

The Swahili coast, stretching along the eastern coast of Africa, was home to a blend of African and Arab Muslim traders who established vibrant trading cities like Kilwa, Mombasa, and Zanzibar. These cities emerged as important commercial hubs from around the 8th century, facilitating trade between Africa, the Middle East, and beyond. The interaction between African cultures and Muslim traders led to the development of the Swahili language and culture, characterized by a unique blend of African and Arab influences. Thus, both Africans and Muslim traders played crucial roles in shaping the history and economy of the Swahili coast.
