Drangiana or Zarangiana (Greek: Δραγγιανή, Drangianē; also attested in Old Western Iranian as 𐏀𐎼𐎣, Zraka or Zranka,[3] was a historical region and administrative division of the Achaemenid Empire.
Drangiana was possibly subdued by another Iranian people, the Medes, and later, certainly, by the expanding Persian Achaemenid Empire of Cyrus the Great (559-530 BC).
[4] According to Herodotus, during the reign of Darius I (522-486 BC), the Drangians were placed in the same district as the Utians, Thamanaeans, Mycians, and those deported to the Persian Gulf.
The capital of Drangiana, called Zarin or Zranka (like the Province), is identified with great probability with the extensive Achaemenid site of Dahan-e Gholaman southeast of Zabol in Iran.
The history of Drangiana during the weakening of Seleucid rule is unclear, but by the mid-2nd century BC the area was conquered by the expanding Parthian Empire of the Arsacids.
