Transoxiana

Transoxiana (also spelled Transoxania) is the ancient name used for the portion of Central Asia corresponding approximately with modern-day Uzbekistan, Tajikistan, southern Kyrgystan and southwest Kazakhstan. Geographically, it is the region between the Amu Darya (Ancient Greek: Ώξος Ōxos) and Syr Darya rivers. When used in the present, it usually implies that one is talking about that region in the time prior to about the 8th century, although the term continued to remain in use among western historians for several centuries after. In the Persian epic Shahnameh, written by the poet Ferdowsi, Transoxiana is the homeland of the Iranian nomadic tribes and the Oxus river is the border between Iran and Turan.

The region was one of the satrapies of the Achaemenid dynasty of Persia under the name Sogdiana. Transoxiana, however, is Latin, and literally means "across the Oxus River", the Greek name for the Amu Darya, which describes the region perfectly from the viewpoint of the Greeks and Romans. The area was called prdry and Faraa-rood in Middle Persian, the latter means "that which is beyond the river". After invasion of Arabs they called it mā warā' an-nāhr which is a translation of the Mid. Persian name and has the same meaning, and is an alternative name for the country, and is also rendered Mawarannahr.
