Based on Mesopotamian texts, the land of Kerman has been in contact with the Persian Gulf trade since the beginning of the history. Greek and Islamic geographers have also admitted the connection between this land and the Sea. Besides, Kerman Sea has been among of the names of the Sea of Oman. What is the relationship between this land and the sea during the Achaemenid period? Historical resources suggest that during the Achaemenid period, the Satrapy of Kerman was formed from a combination of old parts such as the Parikani (?kaufa?iya), the Yutiya and Maka that had formerly been in contact with the sea. Unfortunately, these resources, except for the names of several ports, do not provide any further information on the connections between Kerman and the Sea during the Achaemenid period, but more information can be obtained from the Persepolis archives. These texts illustrate Kerman as an independent Satrapy having an important administrative and economic position. Its Satrap, Karki?, during the reign of Darius, dominated a region that on the one hand, began from Neyriz in the south-east of Fars to the east of Iran (Fahraj) on the trade route to India, and on the other hand, was connected to the Persian Gulf islands in the south.
