Archaeological finds document continued occupation of the Orkhon Valley during the last 100,000 years. It is considered the cradle of central Asian nomadic civilizations. Different ancient people, like the Huns and the Uighur, settled here commencing in the 3rd century B.C.
The Huns are nomadic people who lived in Central Asia, north of China (present day Mongolia). They attacked large parts of Asia and Europe. They lived in the steppes of Asia characterized by hot summers and cold winters. These grasslands are a windy, partly-dry biome, a sea of grass. The evaporation rate is high, so the rich soil is able to retain a large part of the little rain that falls. They had flat treeless plains and alternating steeps that helped make them expert horsemen. There nomadic way of life, including raising cattle, enduring both heat and cold, and the use of conflexive bows in battle, made from strong natural material, helped them conquer large areas of land. The Huns lived from their herds and by attacking villages for resources. The Huns were organized in close knit tribes that worshiped the natural world that helped them survive.
