Having given a big impression on World history, Turkish tribes or states had to migrate from their mainland in Central Asia to west because of lack of climate, shrinking their greenland, various diseases and a number of political reasons. This massive migration movement on different parts of regions inevitably required to struggle with each other. Being mentioned on Russian history, Cuman-Qipchaqs had a great area from caucasia, moorland in the Black Sea, Middle Europe, Balkans to Anatolian geography. In this vast geography, Cuman-Qipchaqs interacted with some strong states during that period such as Khazar, Mongol, Georgian, Selcuks, Russian, Bulgarian, Hungarian and Byzantine Empire. From the late of thirteenth century to fifteenth century, in East European geography Cuman-Qipchaqs lived for a long time after Peçeneks. Cumans and Russia were sometimes enemy and sometimes allied forces. And they acguired big achivements over military and political area. Cuman ladies were effective to help to Kievan Rus when they had a conflict . And therefore Cumans interfered in Kievan internal affairs and they acguired a big proportion of property from Russia. The invasion of Kievan Rus to cumans caused Russia to defeat heavily against cumans. Until mongols arrived in border of East Europe, these two states remained to live between this struggle and relativity. During their period, Cuman-Qipchaqs cut Russian invasion for a long time, dominating a strategic region at the north of Black Sea and they enabled this territory to remain as Turkish land.
