Syr Darya
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 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 Inadequate infrastructure, poor water-management, and outdated irrigation methods all exacerbate the issue.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 the 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.
