The Ethnic composition of Contemporary Central Asian society reflects historical accumulation of various civilizations inflows in Central Asia. The pattern of Social Conflict in Central Asian Countries are categorized to relations between indigenous group & deported ethnic groups or relations among indigenous ethnic groups. Social conflict pattern of the former group occurred from last period of Soviet Union to beginning of independent Central Asian countries. And conflict pattern of the tatter group have been continuing since breaking of Soviet Union to the present in Central Asian Society. The Ferghana Valley, which is located at Eastern-northern Uzbekistan, Western-Northern Kyrgyzstan and Northern Tajikistan, is a symbol of Multi-ethnic character of Central Asian Society From the medieval period various ethnic groups settled and kept their traditional way of Life; nomadic, semi-nomadic and settled communities by ethnic groups. In the formation of Soviet Union this region was divided by Soviet new ethnic categories, which were not able to cover local ethnic structure of the Ferghana Valley and which created Uzbekistan, Kyrgyzstan and Tajikistan. The Soviet authorities seriously considered dividing of Ferghana Vally in terms of effective ruling, so poly-ethnic structure & economical linkage among local communities did not affected on the creating new ethno-territorial units in Soviet union. The delimitation of the Ferghana Valley in Soviet period did not change everyday life of populations of Ferghana valley, regardless of ethnic groups, because those days inter-republic borders had no actual meaning in the frame of Soviet Union. After breaking of Soviet Union, artificial or political inter-republic borders became actual national borders which blocked trans-republic life pattern of populations in the Ferghana Valley.
