The major factor in the longevity of the Swahili city-states' influence was the trade network that connected the city-states to other powers in the Indian Ocean. This trade network allowed for the exchange of goods, ideas, and cultural influences, strengthening the economic and political power of the city-states. The Swahili city-states were strategically located along the coast of East Africa, providing easy access to the Indian Ocean trade routes. This allowed them to establish prosperous trading relationships with various civilizations, such as Persia, India, and China. The trade network brought in a significant amount of wealth and resources, making the Swahili city-states powerful and influential in the region. Additionally, the trade connections also facilitated the spread of Islam in the region, further solidifying their cultural and religious influence. Therefore, the trade network played a crucial role in sustaining the long-lasting influence of the Swahili city-states.
