Arabian Sea

'The offshore waters between Arabia and India formed a route older than the great medieval trading empires of the region. Akkadian texts describe commerce with Tilmun, Magan, and Meluhha, names associated with the Gulf and Indus trading worlds. Such references show that goods moved through maritime corridors linking Mesopotamia with the coasts of the Arabian Sea long before later states controlled major ports.

The sea’s northern basin connects the Gulf of Oman with approaches to India, while southern branches lead toward East Africa and the Red Sea. Square-rigged ships depended on the northeast–southwest drift of the monsoon, and the strength of the winds determined when fleets could sail and return. Ports flourished where a protected anchorage met inland routes.

Even when empires changed, these sea roads sustained exchange in metals, textiles, ceramics, food, and ideas, making the basin a meeting ground between Persian Gulf, Arabian, African, and South Asian societies. finds from the Belitung shipwreck and later Phanom Surin wreck shows that ceramics and perishable goods moved between China, Southeast Asia, and Gulf merchants. Ming voyages under Zheng He later followed branches through the Arabian Sea toward Africa and the Red Sea.
