The Dilmun civilization was the centre of commercial activities linking traditional agriculture of the land—then utterly fertile due to artesian wells that have dried since, and due to a much wetter climate—with maritime trade between diverse regions such as the Meluhha (suspected to be Indus Valley Civilisation), Magan (Oman), and Mesopotamia. The Dilmun civilization is mentioned first in Sumerian cuneiform clay tablets dated to the late third millennium BC, found in the temple of goddess Inanna, in the city of Uruk.
