Alexandria in Arachosia was a city in ancient times that is now called Kandahar in Afghanistan. It was one of the seventy-plus cities founded or renamed by Alexander the Great. Arachosia is the Greek name of an ancient province of the Achaemenid, Seleucid and Parthian empires. The province of Arachosia corresponds to today's southeastern Afghanistan and western Pakistan, the ethnic Pashtun territory.
Isidorus of Charax in his 1st century CE "Parthian stations" itinerary described an "Alexandropolis, the metropolis of Arachosia", which he said was still Greek even at such a late time:
"Beyond is Arachosia. And the Parthians call this White India; there are the city of Biyt and the city of Pharsana and the city of Chorochoad and the city of Demetrias; then Alexandropolis, the metropolis of Arachosia; it is Greek, and by it flows the river Arachotus. As far as this place the land is under the rule of the Parthians."
