History of Central Asia
The history of Central Asia concerns the history of the various peoples that have inhabited Central Asia. The lifestyle of such people has been determined primarily by the area's climate and geography. The aridity of the region makes agriculture difficult and distance from the sea cut it off from much trade. Thus, few major cities developed in the region. Nomadic horse peoples of the steppe dominated the area for millennia.
Relations between the steppe nomads and the settled people in and around Central Asia were marked by conflict. The nomadic lifestyle was well suited to warfare, and the steppe horse riders became some of the most militarily potent people in the world, due to the devastating techniques and ability of their horse archers. Periodically, tribal leaders or changing conditions would cause several tribes to organize themselves into a single military force, which would then often launch campaigns of conquest, especially into more 'civilized' areas. A few of these types of tribal coalitions included the Huns' invasion of Europe, various Turkic migrations into Transoxiana and most notably the Mongol conquest of much of Eurasia.
The dominance of the nomads ended in the 16th century as firearms allowed settled people to gain control of the region. The Russian Empire, the Qing dynasty of China, and other powers expanded into the area and seized the bulk of Central Asia by the end of the 19th century. After the Russian Revolution of 1917, the Soviet Union incorporated most of Central Asia; only Mongolia and Afghanistan remained nominally independent, although Mongolia existed as a Soviet satellite state and Soviet troops invaded Afghanistan in the late 20th century. The Soviet areas of Central Asia saw much industrialization and construction of infrastructure, but also the suppression of local cultures and a lasting legacy of ethnic tensions and environmental problems.
With the collapse of the Soviet Union in 1991, five Central Asian countries gained independence — Kazakhstan, Uzbekistan, Turkmenistan, Kyrgyzstan, and Tajikistan. In all of the new states, former Communist Party officials retained power as local strongmen, with the partial exception of Kyrgyzstan which, despite ousting three post-Soviet presidents in popular uprisings, has as yet been unable to consolidate a stable democracy.
Prehistory
Homo sapiens reached Central Asia by 50,000 to 40,000 years ago. The Tibetan Plateau is thought to have been reached by 38,000 years ago. The currently oldest modern human sample found in northern Central Asia, is a 45,000-year-old remain, which was genetically closest to ancient and modern East Asians, but his lineage died out quite early.Paleolithic Central Asia was characterized by a distinctive but deeply European-related population, with subsequent geneflow from Paleo-Siberians, contributing East Asian-related ancestry towards Paleolithic Central Asians. During the Bronze Age, ancient Central Asia received various migration events from Europe and the Middle East, associated with Indo-Europeans. Bronze Age Central Asia consisted largely of Iranian peoples, with some groups being of Paleo-Siberian and Samoyedic origin. Since the early Iron Age, Central Asia received noteworthy amounts of migration from East Asian-related populations, and became increasingly diverse. The Turkic peoples slowly replaced and assimilated the previous Iranian-speaking locals, turning the population of Central Asia from largely Iranian, into primarily of East Asian descent. Modern Central Asians are characterized by both West-Eurasian and East-Eurasian ancestry, with the majority being of primarily East Asian ancestry, and can be linked to expanding Turkic peoples outgoing from Mongolia and Northeast Asia.
The term Ceramic Mesolithic is used of late Mesolithic cultures of Central Asia, during the 6th to 5th millennia BC. It is characterized by its distinctive type of pottery, with point or knob base and flared rims, manufactured by methods not used by the Neolithic farmers. The earliest manifestation of this type of pottery may be in the region around Lake Baikal in Siberia. It appears in the Elshan or Yelshanka or Samara culture on the Volga in Russia by about 7000 BC. and from there spread via the Dnieper-Donets culture to the Narva culture of the Eastern Baltic.
The Botai culture is suggested to be the earliest culture to have domesticated the horse. The four analyzed Botai samples had about 2/3 European-related and 1/3 East Asian-related ancestry. The Botai samples also showed high affinity towards the Mal'ta boy sample in Siberia.
In the Pontic–Caspian steppe, Chalcolithic cultures develop in the second half of the 5th millennium BC, small communities in permanent settlements which began to engage in agricultural practices as well as herding. Around this time, some of these communities began the domestication of the horse. According to the Kurgan hypothesis, the north-west of the region is also considered to be the source of the root of the Indo-European languages. The horse-drawn chariot appears in the 3rd millennium BC, by 2000 BC, in the form of war chariots with spoked wheels, thus being made more maneuverable, and dominated the battlefields. The growing use of the horse, combined with the failure, roughly around 2000 BC, of the always precarious irrigation systems that had allowed for extensive agriculture in the region, gave rise and dominance of pastoral nomadism by 1000 BC, a way of life that would dominate the region for the next several millennia, giving rise to the Scythian expansion of the Iron Age.
Scattered nomadic groups maintained herds of sheep, goats, horses, and camels, and conducted annual migrations to find new pastures. The people lived in yurts – tents made of hides and wood that could be disassembled and transported. Each group had several yurts, each accommodating about five people.
While the semi-arid plains were dominated by the nomads, small city-states and sedentary agrarian societies arose in the more humid areas of Central Asia. The Bactria-Margiana Archaeological Complex of the early 2nd millennium BC was the first sedentary civilization of the region, practicing irrigation farming of wheat and barley and possibly a form of writing. Bactria-Margiana probably interacted with the contemporary Bronze Age nomads of the Andronovo culture, the originators of the spoke-wheeled chariot, who lived to their north in western Siberia, Russia, and parts of Kazakhstan, and survived as a culture until the 1st millennium BC. These cultures, particularly Bactria-Margiana, have been posited as possible representatives of the hypothetical Aryan culture ancestral to the speakers of the Indo-Iranian languages.
Later the strongest of Sogdian city-states of the Fergana Valley rose to prominence. After the 1st century BC, these cities became home to the traders of the Silk Road and grew wealthy from this trade. The steppe nomads were dependent on these settled people for a wide array of goods that were impossible for transient populations to produce. The nomads traded for these when they could, but because they generally did not produce goods of interest to sedentary people, the popular alternative was to carry out raids.
A wide variety of people came to populate the steppes. Nomadic groups in Central Asia included the Huns and other Turks, as well as Indo-Europeans such as the Tocharians, Persians, Scythians, Saka, Yuezhi, Wusun, and others, and a number of Mongol groups. Despite these ethnic and linguistic differences, the steppe lifestyle led to the adoption of very similar culture across the region.
Ancient era
In the 2nd and 1st millennia BC, a series of large and powerful states developed on the southern periphery of Central Asia. These empires launched several attempts to conquer the steppe people but met with only mixed success. The Median Empire and Achaemenid Empire both ruled parts of Central Asia. The Xiongnu Empire may be seen as the first central Asian empire which set an example for later Göktürk and Mongol empires. Xiongnu's ancestor Xianyu tribe founded Zhongshan state in Hebei province, China. The title chanyu was used by the Xiongnu rulers before Modun Chanyu so it is possible that statehood history of the Xiongnu began long before Modun's rule.Following the success of the Han–Xiongnu War, Chinese states would also regularly strive to extend their power westwards. Despite their military might, these states found it difficult to conquer the whole region.
When faced by a stronger force, the nomads could simply retreat deep into the steppe and wait for the invaders to leave. With no cities and little wealth other than the herds they took with them, the nomads had nothing they could be forced to defend. An example of this is given by Herodotus's detailed account of the futile Persian campaigns against the Scythians. The Scythians, like most nomad empires, had permanent settlements of various sizes, representing various degrees of civilisation. The vast fortified settlement of Kamenka on the Dnieper River, settled since the end of the 5th century BC, became the centre of the Scythian kingdom ruled by Ateas, who lost his life in a battle against Philip II of Macedon in 339 BC.
Some empires, such as the Persian and Macedonian empires, did make deep inroads into Central Asia by founding cities and gaining control of the trading centres. Alexander the Great's conquests spread Hellenistic civilisation all the way to Alexandria Eschate, established in 329 BC in modern Tajikistan. After Alexander's death in 323 BC, his Central Asian territory fell to the Seleucid Empire during the Wars of the Diadochi.
In 250 BC, the Central Asian portion of the empire seceded as the Greco-Bactrian Kingdom, which had extensive contacts with India and China until its end in 125 BC. The Indo-Greek Kingdom, mostly based in the Punjab region but controlling a fair part of Afghanistan, pioneered the development of Greco-Buddhism. The Kushan Kingdom thrived across a wide swath of the region from the 2nd century BC to the 4th century AD, and continued Hellenistic and Buddhist traditions. These states prospered from their position on the Silk Road linking China and Europe.
Likewise, in eastern Central Asia, the Chinese Han dynasty expanded into the region at the height of its imperial power. From roughly 115 to 60 BC, Han forces fought the Xiongnu over control of the oasis city-states in the Tarim Basin. The Han was eventually victorious and established the Protectorate of the Western Regions in 60 BC, which dealt with the region's defence and foreign affairs. Chinese rule in Tarim Basin was replaced successively with Kushans and Hephthalites.
Later, external powers such as the Sassanid Empire would come to dominate this trade. One of those powers, the Parthian Empire, was of Central Asian origin, but adopted Persian-Greek cultural traditions. This is an early example of a recurring theme of Central Asian history: occasionally nomads of Central Asian origin would conquer the kingdoms and empires surrounding the region, but quickly merge into the culture of the conquered peoples.
At this time Central Asia was a heterogeneous region with a mixture of cultures and religions. Buddhism remained the largest religion, but was concentrated in the east. Around Persia, Zoroastrianism became important. Nestorian Christianity entered the area, but was never more than a minority faith. More successful was Manichaeism, which became the third largest faith.
Turkic expansion began in the 6th century; the Turkic speaking Uyghurs were one of many distinct cultural groups brought together by the trade of the Silk Route at Turfan, which was then ruled by China's Tang dynasty. The Uyghurs, primarily pastoral nomads, observed a number of religions including Manichaeism, Buddhism, and Nestorian Christianity. Many of the artefacts from this period were found in the 19th century in this remote desert region.
