The Syr Darya, historically known as the Jaxartes ( ; ), is a river in Central Asia. The name, which is Persian, literally means Syr Sea or Syr River. It originates in the Tian Shan mountains in Kyrgyzstan and eastern Uzbekistan, and flows for west and north-west through Uzbekistan, Sughd province of Tajikistan, and southern Kazakhstan to the northern remnants of the Aral Sea. It is the northern and eastern of the two main rivers in the endorheic basin of the Aral Sea, the other being the Amu Darya.

During the Soviet era, extensive irrigation projects were constructed around both rivers, diverting their water into farmland and causing, during the post-Soviet era, the virtual disappearance of the Aral Sea, once the world's fourth-largest lake. The point at which the river flows from Tajikistan into Uzbekistan is, at above sea level, the lowest elevation in Tajikistan.

Name

The second part of the name (, ) means "lake" or "sea" in Persian and "river" in the Tajik language. The current name dates only from the 18th century.

The earliest recorded name was Jaxartes or Iaxartes () in Ancient Greek, consist of two morpheme Iaxa and artes, found in several sources, including those relating to Alexander the Great. This variant of the Greek name hearkens back to the Old Persian name Yakhsha Arta ("True Pearl"), perhaps a reference to the color of its glacially-fed water. However there is also usage of the name Tanais river in certain sources, such as those of Arrian, a possible usage of the actual Tanais River's name to represent a furthest east river by distance. More evidence for the Persian etymology comes from the river's Turkic name up to the time of the Arab conquest, the Yinçü, or "Pearl river", from Middle Chinese *t͡ɕiɪn-t͡ɕɨo. Tang Chinese also recorded this name as Yaosha River (MC: *jɨɐk-ʃˠɛt) and later Ye River (MC: *jiɛp).

The current local name of the river, Syr (Sïr), does not appear before the 16th century. In the 17th century, Abu al-Ghazi Bahadur Khan, historian and ruler of Khiva, called the Aral Sea the "Sea of Sïr," or Sïr Tengizi.

The important evidence is the etymology of the name of the Syr-Darya River mentioned by the ancient authors – <nowiki></nowiki>Yaksart<nowiki></nowiki>, established by V. A. Livshits (2003: 10). It means '<nowiki></nowiki>flowing' or 'streaming'.<nowiki></nowiki> The word belongs to the Sogdian dialect that had emerged from the Saka language group.

History

When the Macedonian army of Alexander the Great reached the Jaxartes in 329 BC, after travelling through Bactria and Sogdia without encountering any opposition, they met with the first instances of native resistance to their presence. In October 329 BC the Macedonians fought the Battle of Jaxartes against the Saka, killing some 1,200 combatants including the leader of the nomads. Alexander was forced to retire south to deal with a revolt in Sogdia. Alexander was wounded in the fighting that ensued and the native tribes took to attacking the Macedonian garrisons stationed in their towns. As the revolt against Alexander intensified it spread through Sogdia, plunging it into two years of warfare, the intensity of which surpassed any other conflict of the Anabasis Alexandri.

On the shores of the Syr Darya, Alexander placed a garrison in the City of Cyrus (Cyropolis in Greek), which he then renamed after himself Alexandria Eschate—"Alexandria the furthest"—in 329&nbsp;BC. For most of its history since at least the Muslim conquest of Central Asia in the 7th to 8th centuries AD, the name of this city (in present-day Tajikistan) has been Khujand.

In the mid-19th century, during the Russian conquest of Turkestan, the Russian Empire introduced steam navigation to the Syr Darya, initially from Fort Raim but with an important river port at Kazalinsk (Kazaly) from 1847 to 1882, when service ceased.

During the Soviet era, a resource-sharing system was instituted in which Kyrgyzstan and Tajikistan shared water originating from the Amu Darya and Syr Darya rivers with Kazakhstan, Turkmenistan, and Uzbekistan in summer. In return, Kyrgyzstan and Tajikistan received Kazakh, Turkmen, and Uzbek coal, gas, and electricity in winter. After the 1991 fall of the Soviet Union, this system disintegrated and the Central Asian nations have failed to reinstate it. Inadequate infrastructure, poor water-management, and outdated irrigation methods all exacerbate the issue.

In 2012, the Syrdarya–Turkestan State Regional Natural Park was opened in Kazakhstan, in hopes of protecting the river plain ecosystems, archaeological sites, and historical-cultural monuments, as well as plants and animal species, some of which are rare or endangered.

Geography

The river rises in two headstreams in the Tian Shan Mountains in Kyrgyzstan and eastern Uzbekistan—the Naryn River and the Kara Darya which come together in the Uzbek part of the Fergana Valley—and flows for some west and north-west through Uzbekistan and southern Kazakhstan to the remains of the Aral Sea. The Syr Darya drains an area of over , but no more than actually contribute significant flow to the river: indeed, two of the largest rivers in its basin, the Talas and the Chu, dry up before reaching it. Its annual flow is a very modest
