On the site of modern Leninabad (Khojent) on the Jaxartes in Sogdiana, Alexander founds a city, Alexandreschate, “Alexandria the Farthest,” not far from the site of Cyropolis, a city of Cyrus II the Great, whom he highly admires. (There is evidence of Achaemenid irrigation at the interesting Bactrian site of Ai Khanum, which cannot definitely be identified as an Alexandria.)

Alexandreschate is a prestige foundation, designed, as explicitly stated by Arrian, for both military and commercial success.

Alexander has already planted a number of new Alexandrias in central Iran, including Alexandria in Areia (Herat), Alexandria in Arachosia, and almost certainly Kandahar (on the exciting evidence of a metrical inscription found there by a British excavation team in 1978).
