Where is Transoxiana?
Transoxiana
The name Transoxiana stuck in Western consciousness because of the exploits of Alexander the Great, who extended Greek culture into the region with his invasion in the 4th century BC; Transoxiana was the most north-eastern point of the Hellenistic culture until the Arab invasion. During the Sassanid Empire, it was often called Sogdiana, a provincial name taken from the Achaemenid Empire, and used to distinguish it from nearby Bactria.
