Here's a breakdown:
* Culture: Their culture was a blend of African and Arab influences. This was due to their location on the East African coast, which facilitated trade with the Arab world.
* Language: Swahili, a Bantu language heavily influenced by Arabic, was their primary language. This language evolved through centuries of interactions between Arab traders and the Bantu-speaking coastal communities.
* Religion: While the dominant religion in Kilwa was Islam, there were also traces of indigenous beliefs and practices.
It's important to note that the people of Kilwa were not a monolithic group. Their society was comprised of different ethnicities and social classes, each with its own unique traditions and customs. The Swahili language and culture served as a unifying force across these diverse communities.
