Central Asia
Alexander von Humboldt drew the first modern map of Central Asia in 1843, placing its borders between 5 degrees north and south of latitude 44.5 degrees north. He included the Caspian Sea to the west and the Altai mountains to the north but left the eastern boundary undefined. Nikolaï Khanykov later challenged this latitudinal approach by proposing a physical definition based on landlocked status. His version added Afghanistan, Khorasan, East Turkestan, and Mongolia to the list of countries within the region. Russian culture distinguishes between Srednyaya Aziya as a narrower term for historically non-Slavic lands and Tsentralnaya Aziya as a wider concept including areas never part of historical Russia. The Soviet Union officially defined Middle Asia as only Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan while omitting Kazakhstan entirely. In 1991 leaders from four former Soviet republics met in Tashkent and declared that Kazakhstan should be included in the definition of Central Asia. UNESCO adopted an even broader definition in 1978 that encompassed northern India, western China, and Pakistan alongside the Soviet republics. Ethnic definitions now include Xinjiang Uyghur Autonomous Region, southern Siberia's Turkic regions, and Afghan Turkestan as core components of the area.
The world's northernmost desert exists at Buurug Deliin Els in Mongolia located at 50 degrees 18 minutes north latitude. This sandy expanse sits just south of the permafrost zone found at Erdenetsogt sum in Mongolia at 46 degrees 17 minutes north. The distance between these two geographic extremes measures less than 200 kilometers creating one of Earth's most unusual climatic zones. Most land in Central Asia remains too dry or rugged for conventional farming operations. The Gobi Desert stretches from the foot of the Pamirs at 77 degrees east to the Great Khingan Mountains between 116 and 118 degrees east. Major rivers including the Amu Darya and Syr Darya flow northwest into the shrinking Aral Sea. Lake Balkhash and the Caspian Sea form part of a massive endorheic basin that drains no ocean. Water scarcity has become a critical issue as irrigation projects divert river flows away from natural basins. Dust storms frequently occur during late summer months especially in September and October across the region. Average annual precipitation ranges from under 100 millimeters in arid zones to over 300 millimeters in wetter highland areas like Dushanbe.
Caravans traveling along the Silk Road typically followed either the northern or southern side of the Tarim Basin before converging at Kashgar. From there they crossed mountains heading northwest toward Ferghana or southwest toward Bactria. A minor branch extended north of the Tian Shan through Dzungaria and Zhetysu before turning southwest near Tashkent. Cities like Bokhara and Samarkand flourished as trading hubs thanks to the Zarafshan River which watered their markets. Transoxiana served as the heartland for Sogdian merchants who dominated long-distance trade routes for centuries. The Tang dynasty expanded westward controlling large parts of Central Asia directly and indirectly through Turkic vassals until defeated by the Abbasid Caliphate at the Battle of Talas in 751. This battle marked the end of 150 years of Chinese influence in the western regions. Buddhist monasteries spread northward along these same routes eventually reaching China itself. Nomadic groups moved from Mongolia through Dzungaria before turning southwest to conquer settled lands or continuing west toward Europe. The region became a conduit for goods ideas and people moving between Europe and the Far East over many centuries.
Central Asia in the early seventh century remained ethnically an Iranian land where people spoke various Middle Iranian languages. Eastern Iranian-speaking groups including Bactrians Sogdians Chorasmians Scythians and Dahae inhabited the region before significant demographic shifts occurred. The main migration of Turkic peoples took place between the sixth and eleventh centuries when they spread across most of Central Asia. Genetic studies show that modern Kazakhs possess between 22% and 70% East Asian ancestry derived from Baikal hunter-gatherer populations. Tajiks display genetic continuity with Iron Age Indo-Iranians while maintaining distinct linguistic traditions today. Uzbek ancestry clusters somewhere between Iranian peoples and Mongols according to recent DNA analysis. About 27% to 60% of Uzbek ancestry comes from East Asian sources with the remainder composed of European and Middle Eastern components. Turkic speaking groups generally show more homogeneity than their Iranian speaking counterparts in maternal and paternal DNA haplogroups. The Mongol invasion brought enormous demographic success though it did not immediately alter the cultural or linguistic landscape of the region. Slow assimilation of local populations combined with extensive Turkic and later Mongol migrations out of Mongolia transformed the genetic makeup of Central Asians over thousands of years.
The Russian Empire conquered lands of nomadic Kazakhs Turkmens Kyrgyz and Central Asian khanates during the nineteenth century. A major revolt known as the Dungan Revolt erupted in the eastern part of Central Asia during the 1860s and 1870s causing Qing rule to nearly collapse in all of East Turkestan. After the Russian Revolution western Central Asian regions were incorporated into the Soviet Union while Xinjiang became part of the People's Republic of China. Soviet authorities deported millions of people including entire nationalities from western areas of the Soviet Union to Central Asia and Siberia. Between 1959 and 1970 about two million people migrated to Central Asia with approximately one million moving specifically to Kazakhstan. Hundreds of thousands died from failed collectivization programs under Stalinist rule. Industrialization and infrastructure construction accompanied these changes but so did suppression of local cultures and lasting environmental problems. The Soviet era left behind ethnic tensions that continue to shape political dynamics across the five modern republics today. European settlers established communities throughout the region though most now live within Kazakhstan where seven million Russians reside alongside half a million Ukrainians and around 170,000 Germans.
Five countries gained independence following the collapse of the Soviet Union in 1991: Kazakhstan Kyrgyzstan Tajikistan Turkmenistan and Uzbekistan. Former Communist Party officials retained power as local strongmen in nearly all new states creating non-functional democracies during early years. Kyrgyzstan Kazakhstan and Mongolia have made further progress toward open societies unlike Uzbekistan Tajikistan and Turkmenistan which maintained many Soviet-style repressive tactics. Political instability marked the transition period with events like the April 2010 deposition of President Kurmanbek Bakiyev by popular uprising in Kyrgyzstan. Roza Otunbayeva assured interim presidency until Almazbek Atambayev won election in November 2011. Economic shocks hit Kyrgyzstan hard between 2010 and 2012 when food prices rose two consecutive years and production at Kumtor gold mine fell by 60% due to geological movements. Thirty-three point seven percent of Kyrgyz population lived in absolute poverty in 2010 rising to 36.8% the following year despite high regional growth rates elsewhere. GDP per capita reached PPP$23,206 in Kazakhstan and PPP$14,201 in Turkmenistan while dropping to PPP$5,167 for Uzbekistan home to 45% of region's total population.
