The causes of the defeat were following : the turkish government which strived for establishing and strenthening a new national independent state and realizing modernization did not allow the kurdish separatism within its borders ; the kurds lost the support from the western countries because of the international changes ; the division of the kurds themselves 其失败的原因，一是由于谋求建立、巩固新兴民族独立国家和实现现代化的土耳其政府不能容许境内库尔德人的分离主义；二是由于国际形势的变化，库尔德人失去了西方国家的支持；三是与库尔德人自身的分裂有关。
