Megasthenes lived in
Alexandropolis, from where he travelled to
Pataliputra (now
Patna, India) in the
Mauryan Empire, to be received at the court of
Chandragupta Maurya. The region is first referred to in the
Achaemenid-era
Elamite Persepolis fortification tablets. It appears again in the
Old Persian,
Akkadian and
Aramaic inscriptions of
Darius I and
Xerxes I among lists of subject peoples and countries. It is subsequently also identified as the source of the ivory used in Darius' palace at Susa. In the
Behistun inscription (DB 3.54-76), the King recounts that a
Persian was thrice defeated by the Achaemenid governor of Arachosia, Vivana, who so ensured that the province remained under Darius' control. It has been suggested that this "strategically unintelligible engagement" was ventured by the rebel because "there were close relations between Persia and Arachosia concerning the Zoroastrian faith." The
Kushans captured Arachosia from the Indo-Parthians and ruled the region until around 230 CE, when they were defeated by the
Sassanids, the second Persian Empire, after which the Kushans were replaced by Sassanid vassals known as the
Kushanshas or
Indo-Sassanids. In 420 CE the Kushanshas were driven out of present Afghanistan by the
Chionites, who established the
Kidarite Kingdom. The
Kidarites were replaced in the 460s CE by the
Hephthalites, who were defeated in 565 CE by a coalition of Persian and Turkish armies. Arachosia became part of the surviving
Kushano-Hephthalite Kingdoms of
Kapisa, then
Kabul, before coming under attack from the Moslem Arabs. These kingdoms were at first vassals of Sassanids. Around 870 CE the Kushano-Hephthalites (aka Turkshahi Dynasty) was replaced by the
Saffarids, then the
Samanid Empire and Muslim Turkish
Ghaznavids in the early 11th century CE. Arab geographers referred to the region (or parts of it) as 'Arokhaj', 'Rokhaj', 'Rohkaj' or simply 'Roh'. ==Inhabitants==
