东突厥在隋末唐初经历了一个由极盛到衰败的过程,这一过程与中原地区由动乱衰弱到统一强大的过程此消彼长。一旦中原地区出现统一强盛的局面,东突厥不仅在与中原关系中处于劣势,且与周边其他民族政权的关系也随之处于不利的境地。经历了几十年与中原地区诸政治势力关系的演变,东突厥政权最终为唐朝击溃败亡。 East Turkestan experienced a process from extremes to decline in the late Sui and Tang dynasties, a process that contradicted the course of the Central Plains from the breakdown of turmoil to the unification and strengthening of the Central Plains. Once a unified and prosperous situation has emerged in the Central Plains, the East Turkestan is not only at a disadvantage in its relations with the Central Plains, but also at a disadvantage in its relations with the other ethnic groups in the region. After decades of evolving relations with the political forces in the Central Plains, the East Turkestan Regime eventually defeated the defeat of the Tang Dynasty.
