Sogdia lay 20 miles north of Bactria.
Unlike the empires of antiquity, the Sogdian region was not a territory confined within fixed borders, but rather a network of city-states, from one oasis to another, linking Sogdiana to Byzantium, India, Indochina and China
== History ===== Prehistory ===Sogdiana possessed a Bronze Age urban culture: original Bronze Age towns appear in the archaeological record beginning with the settlement at Sarazm, Tajikistan, spanning as far back as the 4th millennium BC, and then at Kk Tepe, near modern-day Bulungur, Uzbekistan, from at least the 15th century BC
