basin. Note the Tien Shan mountains of Kyrgyzstan in the south. The area north of the Tien Shan needs special treatment because of better documentation and the large number of peoples who moved through it. It is a type of
steppe "bay" bounded on the north by the Siberian forests, on the south by the Kyrgyz mountains and on the east by low mountains.
Zhetysu is Turkic and
Semirechye () is Russian for "seven rivers". •
Sakas (before 200 BC): The Iranian-speaking nomads in the western and central steppe were called Scythians by the Greeks,
Sakas by the Persians and Sai by the Chinese; the three words mean about the same thing. The Sakas also occupied the western Tarim basin. Iranian languages extended south to Persia and Afghanistan. • Chinese: Under the
Han dynasty the Chinese expanded westward. In 125 BC
Zhang Qian returned with the first reports of the Western Regions. Around 100 BC to 100 AD, with interruptions, the Chinese controlled the Tarim Basin southeast of the central steppe. Chinese historians have given us the earliest surviving good written information about the central steppe. • Yuezhi ( 162–132 BC): The
Yuezhi were originally a major power in
Gansu and Mongolia. Around 162 BC, driven west by the Xiongnu, they settled in the
Ili valley, driving out the Sakas. About 132 BC, they were driven out by the Wusun and moved south and later formed a major state in
Bactria as the
Kushans. • Wusun ( 133 BC–100 AD): The
Wusun from Gansu drove the Yuezhi out of the Ili valley. By 80 BC they had some power in the Tarim basin. After 100 AD, they declined and gradually disappear from the records. • Xiongnu ( 40 BC – 155 AD): When the Northern
Xiongnu were driven west by the Chinese they occupied Dzungaria and Semirechye, perhaps somewhat north of the Wusun. The
Xianbei who defeated them may also have reached this area. • Yueban ( 160–490 AD): After the Han lost control of the Tarim basin, written sources become sparse. The Chinese called the local population
Yueban or
Yuepan. They appear to have been Xiongnu remnants. • ?Ephthalites ( 493?–560 AD): The poorly-documented
Ephthalites were based in the south and may have extended north of the Tian Shan. •
Tiele people ( 100–800 AD):
Tiele is a vague Chinese term, likely referring to the probably Turkic peoples living mainly on the northern edge of the steppe, from Mongolia westward. •
Outside influences ( 500–800 AD): Turkic-speaking peoples spread from Mongolia and occupied the central steppe. The Chinese returned under the
Tang dynasty of 618–907.
Islam arrived about 750. Meanwhile,
Sogdian merchants controlled most of the long-distance trade. •
Gokturks ( 558–657): The
Gokturks became the first Turkic-speakers to found an empire and the first to rule both the eastern and central steppe (the only other case being the
Mongols). In 552 they took over Mongolia, 558 they reached the
Volga and they reached the
Oxus. By 603, the
Western Turkic Khaganate had definitely split from the Eastern Khaganate in Mongolia. Circa 657, they were defeated by the Chinese. • Chinese again ( 657–756): the Tang dynasty restored Chinese power. The
Tang took over the Tarim basin and the mountains of Kyrgyzstan, captured Tashkent, subjugated what was left of the western Turks and
lost a battle to the Arabs in 751. Around 756 they withdrew because of the
An Lushan rebellion. •
Muslims ( 750–present): After the Arab conquest of
Merv in 651, there were raids northward. From 705, Muslims
expanded into the area between the Oxus and Syr Darya. Muslims in Central Asia soon became more Persian than Arab. From around 750, Islam expanded slowly north of the Syr Darya and into the Tarim Basin and Gansu. • Sogdian Merchants ( 300–840): Merchants from
Sogdia controlled most of the trade between China and the west. They had settlements all the way from
Bukhara to northern China. •
Dulu Turks ( 603–659): The Dulu formed the semi-independent eastern half of the Western Turkic Khaganate. • Chinese vassals ( 658–756): After the defeat of the Gokturks the Chinese had some limited control of the peoples west and north of the mountains, but the matter remains poorly documented. • Turgesh ( 699–766): The
Turgesh were Dulu who restored a kind of Turkic Khaganate. They fought against the Arabs and the Chinese. • Karluks ( 766–840): The Turkic
Karluks drove the Turgesh out of Semirechye and later evolved into the Karakhanids. As a tribe they originated in Dzungaria and existed from at least 644 into Mongol times. •
Karakhanids ( 850–1134): Karluks and others founded the
Karakhanid Khaganate. Around 960 the Karakhanids adopted Islam; they conquered
Transoxiana. About 1041 they split into an eastern group in Semirechye and a western group in Transoxiana. By 1081 they were
Seljuk vassals, at least in theory. Following their defeat in 1134, many Karakhanids remained as local rulers. •
Karakitai (1134–1220): The
Karakitai rulers were refugees from north China. The
Manchurian Khitans ruled north China as the
Liao dynasty (907–1125). After the
Jurchens overthrew them, Khitan remnants fled west, conquered Semirechye in 1134, and by 1141, held most of the lands of the Karakhanids. They were non-Muslim, had some degree of Chinese culture and generally left the former rulers in place as vassals. In 1211, a
Naiman prince who had fled the Mongols usurped power. The Mongols pursued him and by 1220 conquered most of the Karakitai lands. •
Mongols After the
Mongol conquest of the area in 1220 the eastern third of the central steppe does not need separate treatment: see the
"Mongols and after" section below. Subsequent Zhetysu history involved the following: • Chagataids: When the
Mongol empire split up, central Asia fell to the
Chagataids in 1266, but they never formed a strong state and soon adopted Islam and the local language. •
Moghulistan ( 1450–1500): Moghulistan emerged from the declining
Chagatai Khanate. Zhetysu became split between Mogulistan in the east and the emerging Kazakhs. •
Kazakhs (1465–present) first appeared in Zhetysu and soon spread their name all over the central steppe. Semirechye was under the
Senior Horde. •
Dzungar Khanate ( 1680–1758) held the area until it was destroyed by the Chinese. • Russians conquered the area from the north in 1847–68. See
