context_page_description: The Achaemenid conquest of the Indus Valley refers to the Achaemenid military conquest and occupation of the territories of the North-western regions of the Indian subcontinent, from the 6th to 4th centuries BC. The conquest of the areas as far as the Indus river is often dated to the time of Cyrus the Great, in the period between 550-539 BCE. The first secure epigraphic evidence, given by the Behistun Inscription, gives a date before or about 518 BCE. Achaemenid penetration into the area of the Indian subcontinent occurred in stages, starting from northern parts of the River Indus and moving southward. These areas of the Indus valley became formal Achaemenid satrapies as mentioned in several Achaemenid inscriptions. The Achaemenid occupation of the Indus Valley ended with the Indian campaign of Alexander the Great circa 323 BCE. The Achaemenid occupation, although less successful than that of the later Greeks, Sakas or Kushans, had the effect of acquainting India to the outer world.
context_section_description: For millennia, the northwestern part of India had maintained some level of trade relations with the Near East. Finally, the Achaemenid Empire underwent a considerable expansion, both east and west, during the reign of Cyrus the Great (c.600–530 BC), leading the dynasty to take a direct interest into the region of northwestern India.
  Cyrus the Great
  The conquest is often thought to have started circa 535 BCE, during the time of Cyrus the Great (600-530 BCE). Cyrus probably went as far as the banks of the Indus river and organized the conquered territories under the Satrapy of Gandara (Old Persian cuneiform: 𐎥𐎭𐎠𐎼, Gadāra, also transliterated as Gaⁿdāra since the nasal "n" before consonants was omitted in the Old Persian script, and simplified as Gandara) according to the Behistun Inscription. The Province was also referred to as Paruparaesanna (Greek: Parapamisadae) in the Babylonian and Elamite versions of the Behistun inscription. The geographical extent of this province was wider than the Indian Gandhara. Various accounts, such as those of Xenophon or Ctesias, who wrote Indica, also suggest that Cyrus conquered parts of India. Another Indian Province was conquered named Sattagydia (𐎰𐎫𐎦𐎢𐏁, Thataguš) in the Behistun inscription. It was probably contiguous to Gandhara, but its actual location is uncertain. Fleming locates it between Arachosia and the middle Indus. Fleming also mentions Maka, in the area of Gedrosia, as one of the Indian satrapies.
  Darius I
  A successor of Cyrus the Great, Darius I was back in 518 BCE. The date of 518 BCE is given by the Behistun inscription, and is also often the one given for the secure occupation of Gandhara in Punjab. Darius I later conquered an additional province that he calls "Hidūš" in his inscriptions (Old Persian cuneiform: 𐏃𐎡𐎯𐎢𐏁, H-i-du-u-š, also transliterated as Hiⁿdūš since the nasal "n" before consonants was omitted in the Old Persian script, and simplified as Hindush), corresponding to the Indus Valley. The Hamadan Gold and Silver Tablet inscription of Darius I also refers to his conquests in India.
  The exact area of the Province of Hindush is uncertain. Some scholars have described it as the middle and lower Indus Valley and the approximate region of modern Sindh, but there is no known evidence of Achaemenid presence in this region, and deposits of gold, which Herodotus says was produced in vast quantities by this Province, are also unknown in the Indus delta region. Alternatively, Hindush may have been the region of Taxila and Western Punjab, where there are indications that a Persian satrapy may have existed. There are few remains of Achaemenid presence in the east, but, according to Fleming, the archaeological site of Bhir Mound in Taxila remains the "most plausible candidate for the capital of Achaemenid India", based on the fact that numerous pottery styles similar to those of the Achaemenids in the East have been found there, and that "there are no other sites in the region with Bhir Mound's potential".
  According to Herodotus, Darius I sent the Greek explorer Scylax of Caryanda to sail down the Indus river, heading a team of spies, in order to explore the course of the Indus river. After a periplus of 30 months, Scylax is said to have returned to Egypt near the Red Sea, and the seas between the Near East and India were made use of by Darius.
  Also according to Herodotus, the territories of Gandhara, Sattagydia, Dadicae and Aparytae formed the 7th province of the Achaemenid Empire for tax-payment purposes, while Indus (called Ἰνδός, "Indos" in Greek sources) formed the 20th tax region.
  Achaemenid army
  The Achaemenid army was not uniquely Persian. Rather it was composed of many different ethnicities that were part of the vast Achaemenid Empire. The army included Bactrians, Sakas (Scythians), Parthians, Sogdians. Herodotus gives a full list of the ethnicities of the Achaemenid army, in which are included Ionians (Greeks), and even Ethiopians. These ethnicities are likely to have been included in the Achaemenid army which invaded India.
