A text from the era of Sargon of Akkad (r. c. 2334-2284 BCE) mentions a shipping industry in Magan, in present-day Oman. Excavations in the cities of Ur and Kish and in Bahrain and other locations along the east coast of the Arabian Peninsula have unearthed goods of Indian origin (including seals). Both indicate that the network of maritime trade was regular, bustling, and well-known as early as 3000 BC. They suggest that Bahrain and other sites along the Persian Gulf were popular docks which would welcome ships arriving from Iraq on their way to and from India.
