The Aras, (also known as the Araz or Araxes or Araks) is a river in the Caucasus. It rises is eastern Turkey and flows along the borders between Turkey and Armenia, between Turkey and the Nakhchivan area of Azerbaijan, between Iran and both Azerbaijan and Armenia, and finally, through Azerbaijan where it is a tributary of the river Kura. It drains the south side of the Lesser Caucasus Mountains; after its confluence with the Kura, it drains the north side of the Lesser Caucasus Mountains. The river's total length is 1,072 kilometres (666 mi), and its watershed covers an area of 102,000 square kilometres (39,000 sq mi). The Aras is one of the longest rivers in the Caucasus.


In classical antiquity, the river was known to the Greeks as Araxes (Greek: Ἀράξης). Its modern Armenian name is Arax or Araks (Armenian: Արաքս). Historically it was also known as Yeraskh (Old Armenian: Երասխ), and its Old Georgian name is Rakhsi (რახსი). In Azerbaijani, the river's name is Araz. In Persian and Kurdish its name is ارس (Aras), and in Turkish it is Aras.


The Aras rises near Erzurum in Turkey, and meets with the Akhurian River southeast of Digor. From Digor it flows along the Armenia–Turkey border, and then runs close to the corridor that connects Turkey to Azerbaijan's Nakhchivan exclave. It then continues along the Iranian-Armenian and the Iranian-Azerbaijan border.[1]

Etymology and history

In Armenian tradition, the river is named after Arast, a great-grandson of the legendary Armenian patriarch Haik.[5] The name was later Hellenized to Araxes and was applied to the Kura-Araxes culture, a prehistoric people who flourished in the valleys of the Kura and Aras. The river is also mentioned in the last chapter of Virgil's Aeneid VIII, as "angry at the bridge," since the Romans built a bridge over it, so that it is thereby conquered. The river Aras has been associated with the biblical rivers Gihon and Pishon.[6] Robert H. Hewsen described Aras as the only "true river" of Armenia and as "Mother Araxes," a symbol of pride to the Armenian people.[7]

According to a legend cited by Strabo, in ancient times, the Araxes river in Armenia had no outflow to the Caspian sea, but spread out in plains and created a lake without outflow.[8]

In Islamic times, the Araxes became known in Arabic parlance as al-Rass (not to be confused with modern-day Ar Rass), and in Perso-Turkish contexts as Aras.[1]

In modern history, the Aras gained significance as a geographic political boundary. Under the terms of the Treaty of Gulistan and the Treaty of Turkmenchay, the river was chosen as the border limit between the Russian Empire and Qajar Iran, as the latter was forced to cede its Caucasian territories to Russia.[9] Because of these 19th-century border changes, one modern, not widely accepted scheme draws Aras River as the line of continental demarcation between Europe and Asia.[10]

Iran and the Soviet Union have built the Aras Dam on the Aras in the Poldasht area in the 20th century, creating the Aras Reservoir. The Meghri Dam is under construction near the Armenian town of Meghri.[11]

Aras Valley

In 2006, a bird research and education center was established by KuzeyDoğa, a Turkish non-governmental organization for nature conservation, in the Aras Valley at the village Yukarı Çıyrıklı, in the Tuzluca district of Iğdır Province, Turkey. It is one of Turkey's two bird-ringing stations that remain active yearly.[12] Between 2006 and 2015, more than 65,000 birds of 198 species were ringed and 258 bird species were observed at this station. Fifty-five percent of the 471 bird species found in Turkey are recorded at this wetland, making it Turkey's most important wetland for birds. The number of ringed and observed 258 bird species comprises 85 percent of the 303 bird species in Iğdır Province. Seven new bird species were observed during the bird ringing activities in 2012 alone, including the raptor Shikra, or Little Banded Goshawk (Accipiter badius), which was new to Turkey's avifauna.[13][14]

A Biology professor at the University of Utah and a president of the KuzeyDoğa Society, Çağan Şekercioğlu, appealed to the Ministry of Forest and Water Management to drop the Tuzluca Dam project, which would destroy the wetland harboring bird wildlife in the Aras Valley.[13][15] In 2013, the ministry granted the site the highest level of conservation status (Nature Conservation Area).
