Sogdia

Ancient Iranian civilization (6th century BCE – 11th century CE)

Sogdia or Sogdiana was an ancient Iranian civilisation located between the Amu Darya and the Syr Darya rivers, in what is now Uzbekistan, Turkmenistan, Tajikistan, Kazakhstan, and Kyrgyzstan. Sogdiana was also a province of the Achaemenid Empire, and is listed on the Behistun Inscription of Darius the Great. Sogdiana was first conquered by Cyrus the Great, the founder of the Achaemenid Empire, and was later annexed by the Macedonian ruler Alexander the Great in 328 BC. It would subsequently change hands under the Seleucid Empire, the Greco-Bactrian Kingdom, the Kushan Empire, the Sasanian Empire, the Hephthalite Empire, the Western Turkic Khaganate, and following the Muslim conquest of Transoxiana.
