A semilegendary land described in Mesopotamian (Sumerian) texts of the Early Dynastic, Akkadian, and Ur III (c 3000 BC) periods as a prosperous seafaring and trading nation. It was very important as a producer of copper for Persian Gulf trade. Sumer traded with Magan and it was probably situated somewhere in the southern part of the Persian Gulf, either in Baluchistan (on the Iranian side) or in Oman (on the other side), or possibly both. Archaeologists working at the site of Umm An-nar, a small island off the west coast of Abu Dhabi, have suggested that it might be Magan.
