Question: Which two seas connected the Muslim trade cities in Africa to trade networks in China and India?

Explanation:

The Mediterranean Sea is connected to the Atlantic Ocean. It is surrounded by the Mediterranean Basin and is a bit enclosed by land. It's enclosed on the north by Southern Europe and on the south by North Africa. The Indian Sea is bounded on the north by Asia and on the west by Africa. The location of these two seas, made it a great trading rout and even til this day, it is used.

The Mediterranean and Indian Sea trade routes connected Southeast Asia, India, Arabia, and East Africa. For a long time, long-distance sea trade moved across a web of routes linking not only those areas, but also East Asia (mostly China). Islam thought well of merchants (their Prophet Muhammad was caravan leader and a trader), and rich Muslim cities created an huge demand for luxury goods. The Indian Sea trade route included Kilwa, Sofala, Mombasa, Malindi, and others. The city-states traded a lot with Great Zimbabwe to obtain gold, ivory, and iron. These materials were then sold to places like India, Southeast Asia, and China. These materials were known as Africa's exports in the Indian Ocean Trading.
