Here's a more detailed breakdown:
* Countries: Swahili culture is most prominent in Kenya, Tanzania, and Uganda, but it also extends to parts of Mozambique, Malawi, Rwanda, Burundi, Somalia, and the Democratic Republic of Congo.
* Coastal regions: Historically, Swahili culture developed along the coast of East Africa, where it was influenced by Arab and other cultures.
* Beyond the coast: Over time, Swahili culture spread inland, and today it is a significant cultural force in many regions of East Africa.
It's important to remember that Swahili culture is diverse and has evolved over time, incorporating various local influences. It is not a monolithic entity but rather a rich tapestry of traditions, languages, and practices that have blended over centuries.
