The Eurasian Steppe, also called the Great Steppe or the steppes, is the vast steppe ecoregion of Eurasia in the temperate grasslands, savannas, and shrublands biome. It stretches from Bulgaria, Romania and Moldova through Ukraine, Russia, Kazakhstan, Xinjiang, and Mongolia to Manchuria, with one major exclave, the Pannonian steppe or Puszta, located mostly in Hungary.
Since the Paleolithic age, the Steppe Route has connected Eastern Europe, Central Asia, Eastern Asia, Southern Asia, and the Middle East economically, politically, and culturally through overland trade routes. The Steppe route is a predecessor not only of the Silk Road which developed during antiquity and the Middle Ages, but also of the Eurasian Land Bridge in the modern era. It has been home to nomadic empires and many large tribal confederations and ancient states throughout history, such as the Xiongnu, Scythia, Cimmeria, Sarmatia, Hunnic Empire, Chorasmia, Transoxiana, Sogdiana, Xianbei, Mongols, and Göktürk Khaganate.
The Eurasian Steppe extends thousands of miles from near the mouth of the Danube almost to the Pacific Ocean. It is bounded on the north by the forests of European Russia, Siberia and Asian Russia. There is no clear southern boundary although the land becomes increasingly dry as one moves south. The steppe narrows at two points, dividing it into three major parts.
On the east side of the former Sino-Soviet border mountains extend north almost to the forest zone with only limited grassland in Dzungaria.
Big mammals of the Eurasian steppe were the Przewalski's horse, the saiga antelope, the Mongolian gazelle, the goitered gazelle, the wild Bactrian camel and the onager. The gray wolf and the corsac fox and occasionally the brown bear are predators roaming the steppe. Smaller mammal species are the Mongolian gerbil, the little souslik and the bobak marmot.
Furthermore, the Eurasian steppe is home to a great variety of bird species. Threatened bird species living there are for example the imperial eagle, the lesser kestrel, the great bustard, the pale-back pigeon and the white-throated bushchat.
The primary domesticated animals raised were sheep and goats with fewer cattle than one might expect. Camels were used in the drier areas for transport as far west as Astrakhan. There were some yaks along the edge of Tibet. The horse was used for transportation and warfare. The horse was first domesticated on the Pontic-Caspian or Kazakh steppe sometime before 3000 BC, but it took a long time for mounted archery to develop and the process is not fully understood. The stirrup does not seem to have been completely developed until 300 AD (see Stirrup, Saddle, Composite bow, Domestication of the horse and related articles).
The World Wide Fund for Nature divides the Eurasian steppe's temperate grasslands, savannas, and shrublands into a number of ecoregions, distinguished by elevation, climate, rainfall, and other characteristics, and home to distinct animal and plant communities and species, and distinct habitat ecosystems.
The major centers of population and high culture in Eurasia are Europe,the Middle East, India and China. For some purposes it is useful to treat Greater Iran as a separate region. All these regions are connected by the Eurasian Steppe route which was an active predecessor of the Silk Road. The latter started in the Guanzhong region of China and ran west along the Hexi Corridor to the Tarim Basin. From there it went southwest to Greater Iran and turned southeast to India or west to the Middle East and Europe. A minor branch went northwest along the great rivers and north of the Caspian Sea to the Black Sea. When faced with a rich caravan the steppe nomads could either rob it, or tax it, or hire themselves out as guards. Economically these three forms of taxation or parasitism amounted to the same thing. Trade was usually most vigorous when a strong empire controlled the steppe and reduced the number of petty chieftains preying on trade. The silk road first became significant and Chinese silk began reaching the Roman Empire about the time that the Emperor of Han pushed Chinese power west to the Tarim Basin.
The nomads would occasionally tolerate colonies of peasants on the steppe in the few areas where farming was possible. These were often captives who grew grain for their nomadic masters. Along the fringes there were areas that could be used for either plowland or grassland. These alternated between one and the other depending on the relative strength of the nomadic and agrarian heartlands. Over the last few hundred years, the Russian steppe and much of Inner Mongolia has been cultivated. The fact that most of the Russian steppe is not irrigated implies that it was maintained as grasslands as a result of the military strength of the nomads.
According to the most widely held hypothesis of the origin of the Indo-European languages, the Kurgan hypothesis, their common ancestor is thought to have originated on the Pontic-Caspian steppe. The Tocharians were an early Indo-European branch in the Tarim Basin. At the beginning of written history the entire steppe population west of Dzungaria spoke Iranian languages. From about 500 AD the Turkic languages replaced the Iranian languages first on the steppe, and later in the oases north of Iran. Additionally, Hungarian speakers, a branch of the Uralic language family, who previously lived in the steppe in what is now Southern Russia, settled in the Carpathian basin in year 895. Mongolic languages are in Mongolia. In Manchuria one finds Tungusic languages and some others.
Tengriism was introduced by Turko-Mongol nomads. Nestorianism and Manichaeism spread to the Tarim Basin and into China, but they never became established majority religions. Buddhism spread from the north of India to the Tarim Basin and found a new home in China. By about 1400 AD, the entire steppe west of Dzungaria had adopted Islam. By about 1600 AD, Islam was established in the Tarim Basin while Dzungaria and Mongolia had adopted Tibetan Buddhism.

Raids between tribes were prevalent throughout the region's history. This is connected to the ease with which a defeated enemy's flocks can be driven away, making raiding profitable. In terms of warfare and raiding, in relation to sedentary societies, the horse gave the nomads an advantage of mobility. Horsemen could raid a village and retreat with their loot before an infantry-based army could be mustered and deployed. When confronted with superior infantry, horsemen could simply ride away and retreat and regroup. Outside of Europe and parts of the Middle East, agrarian societies had difficulty raising a sufficient number of war horses, and often had to enlist them from their nomadic enemies(as mercenaries). Nomads could not easily be pursued onto the steppe since the steppe could not easily support a land army. If the Chinese sent an army into Mongolia, the nomads would flee and come back when the Chinese ran out of supplies. But the steppe nomads were relatively few and their rulers had difficulty holding together enough clans and tribes to field a large army. If they conquered an agricultural area they often lacked the skills to administer it. If they tried to hold agrarian land they gradually absorbed the civilization of their subjects, lost their nomadic skills and were either assimilated or driven out.
Along the northern fringe the nomads would collect tribute from and blend with the forest tribes (see Khanate of Sibir, Buryats). From about 1240 to 1480 Russia paid tribute to the Golden Horde. South of the Kazakh steppe the nomads blended with the sedentary population, partly because the Middle East has significant areas of steppe (taken by force in past invasions) and pastoralism. There was a sharp cultural divide between Mongolia and China and almost constant warfare from the dawn of history until the Qing conquest of Dzungaria in 1757. The nomads collected large amounts of tribute from the Chinese and several Chinese dynasties were of steppe origin. Perhaps because of the mixture of agriculture and pastoralism in Manchuria its inhabitants, the Manchu, knew how to deal with both nomads and the settled populations, and therefore were able to conquer much of northern China when both Chinese and Mongols were weak.
Russian culture and people were much influenced by the Asian nomads in the Russian steppe and the adjoining steppes and deserts. The steppe culture of Russia was shaped in Russia through cross-cultural contact mostly by Slavic, Tatar-Turkic, Mongolian and Iranian people. In addition to ethnicity, also instruments such as the domra, traditional costumes such as kaftan, sarafan, Russian Cossack and tea culture were strongly influenced by the culture of Asian nomadic peoples. The Eurasian steppes play a major role in Russia's more than 1000-year-old history, so that the steppes are a subject of many Russian folk songs.
