The Mongolian conquest
On April 16, 1162 in a yurta (nomad's tent) of the rich noyon (head of a Mongol clan) Yesugey-bakhadur his wife gave birth to his son who was later named as Temujin in honor of a strong and brave Tatar warrior who had been captured by the Mongols (Temujin or Temirchi stands for an iron-forger). Legends tell that the person who was helping the kid delivery was horrified when he saw a piece of dried blood in a small fist of the baby. 27 years later after Temujin had excelled the rest in the hard matter of uniting Mongol tribes and clans, Tory, the khan of the Kireys called him Jeniskhan (of Khan the Victor) that in Mongol sounded like Chingis-khan.
On the edge of the XII and the XIII centuries the political situation in the steppes of the Central Asia and Kazakhstan was marked by increasing fight between the heads of stronger tribal unions for power over the rest tribes. In course of this struggle the energetic and resolute Temujin managed to unite the Central Asian tribes scattered by the war and established a strong state. Chingis-khan empire was formed with active help of the nobility on top of the centralized nomadic society. The newly-formed states were supposed to represent the interests of this nobility top. Therefore the constant war that, alongside with the captured pasture lands, brought salvage valuables to the nomad nobility and thus was a part of the nomads' productive activities. Exactly for this reason the political unification of Central Asia caused cessation of the internal wars between the tribes. It could be supported by the nomadic tribal nobility only on condition that the war, as a permanent source of profit, doesn't stop, but increase and expand.
One of the reasons for Chingis-khan's military success was the unification of major mil.itary forces of Central Asia and Kasakhstan including not only Mongol tribes but also the Turkic ones, first time after the collapse of the Turkic Kaganat.
Conquest plans of Chingis-khan were vast including subjugation of West Asia and Eastern Europe.
The Mongol conquest considerably delayed the formation of the nationality on the territory of Kazakhstan but could not stop the process. Though slowly, but the economic life was gradually stabilizing and people revived the long ago established tendency towards intimacy approaches between tribes with common origin, language material and spiritual culture.
