Saka

The Saka were a group of nomadic Eastern Iranian peoples who lived in the Eurasian Steppe and the Tarim Basin from the 9th century BC to the 5th century AD. The Saka were closely related to the Scythians, and both groups formed parts of the wider Scythian cultures. However, both groups have differing specific geographical and cultural traits. The Saka languages formed part of the Scythian phylum, a branch of the Eastern Iranian languages.

Derived from the earlier Andronovo, Sintashta and Srubnaya cultures, the Saka were later influenced by the Bactria-Margiana Archaeological Culture and Iron-Age East Asian genetic influx. The ancient Persians, ancient Greeks, and ancient Babylonians respectively used the names "Saka," "Scythian," and "Cimmerian" for all the steppe nomads. However, the name "Saka" is used specifically for the ancient nomads of the eastern steppe, while "Scythian" is used for the related group of nomads living in the western steppe.

Prominent archaeological remains of the Sakas include Arzhan, Tunnug, the Pazyryk burials, the Issyk kurgan, Saka Kurgan tombs, the Barrows of Tasmola and possibly Tillya Tepe. In the 2nd century BC, many Sakas were driven by the Yuezhi from the steppe into Sogdia and Bactria and then into the northwest of the Indian subcontinent, where they became known as the Indo-Scythians. Other Sakas invaded the Parthian Empire, eventually settling in Sistan, while others may have migrated to the Dian Kingdom in Yunnan, China. In the Tarim Basin and Taklamakan Desert of today's Xinjiang Uyghur Autonomous Region, they settled in Khotan, Yarkand, Kashgar and other places.

Linguist Oswald Szemerényi studied synonyms of various origins for Scythian and differentiated the following terms: Sakā 𐎿𐎣𐎠, Skuthēs Σκύθης, Skudra 𐎿𐎤𐎢𐎭𐎼, and Sugᵘda 𐎿𐎢𐎦𐎢𐎭.

Derived from an Iranian verbal root sak-, "go, roam" and thus meaning "nomad" was the term Sakā, from which came the names:

From the Indo-European root *(s)kewd-, meaning "propel, shoot" (and from which was also derived the English word shoot), of which *skud- is the zero-grade form, was descended the Scythians' self-name reconstructed by Szemerényi as *Skuδa (roughly "archer"). From this were descended the following exonyms:

A late Scythian sound change from /ð/ to /l/ resulted in the evolution of *Skuδa into *Skula. From this was derived the Greek word Skṓlotoi Σκώλοτοι, which, according to Herodotus, was the self-designation of the Royal Scythians. Other sound changes have produced Sugᵘda 𐎿𐎢𐎦𐎢𐎭.

Although the Scythians, Saka and Cimmerians were closely related nomadic Iranic peoples, and the ancient Babylonians, ancient Persians and ancient Greeks respectively used the names "Cimmerian," "Saka," and "Scythian" for all the steppe nomads, and early modern historians such as Edward Gibbon used the term Scythian to refer to a variety of nomadic and semi-nomadic peoples across the Eurasian Steppe. The name "Scythian" in contemporary modern scholarship generally refers to the nomadic Iranic people who, from the 7th century BC to the 3rd century BC, dominated the steppe and forest-steppe zones to the north of the Black Sea, Crimea, the Kuban valley, as well as the Taman and Kerch peninsulas,while the name "Saka" is used specifically for their eastern members who inhabited the northern and eastern Eurasian Steppe and the Tarim Basin.
