Names as Qeshm, Keshm, Kish and Tunb mark the lengthy stay of Ilamids in the area, several centuries BC. It is, apparently, the island called Alexandria[disambiguation needed] or Aracia by Ptolemy (Book 6, Chap. IV), in the 2nd century CE and as Alexandria by Ammianus Marcellinus (xxiii.6.42) in the 4th century. On account of its strategic geopolitical situation, near the mouth of the Persian Gulf, it has been frequently attacked by invaders including Ilamids (Elamites), Umayyads, Abbasids as well as the Portuguese and English. During Sassanian Empire administration the island was called Abarkawan. According to historical records, Qeshm Island has been famous as a trade and navigation center. Its economy flourished during the Dailamites and Buyid eras, as trade vessels sailed between Qeshm Island and China, India and Africa.
