Maka was already a part of the Achaemenid Empire before Darius the Great came to power in 522 BC - it is mentioned in the Behistun inscription that it was already there when he inherited the throne. It is possible (because Cambyses and Smerdis are not known to have been there) that it was conquered by Cyrus the Great in 542 BC. He is known to have campaigned on the other side of the Persian Gulf (he seems to have lost most of his army in the Gedrosian Desert).
