元朝与清朝相比何以短命皇帝易主明显不足为训
同样是游牧民族建立的王朝，元朝为什么比清朝短命那么多呢？
首先，元朝皇帝普遍短寿，这导致国家极其不稳定。从开国皇帝忽必烈到末代元顺帝之间，有9位皇帝，他们最大的共同点就是短命。这9位皇帝分别是：元成宗活到42岁、元武宗活到30岁、元仁宗活到35岁、元英宗活到20岁、泰定帝活到53岁（这是唯一超过50岁的）、天顺帝活到8岁、元文宗活到28岁、元世宗活到29岁、元宁宗活到7歲。要知道清朝在位时间最长的皇帝康熙享寿69岁，而最高寿的皇子乾隆享寿89岁，所以皇后普遍短命绝对是元朝的硬伤！
其次，royal succession system in the Yuan dynasty had a significant flaw. Since the Yuan dynasty originated from the Mongol Empire, the emperor was not only an emperor but also a khan of Mongolia. The inheritance system of Mongols was "the youngest son remains at home" system. This system, which suited their nomadic lifestyle on the grassland, caused chaos when applied to royal succession in China. First, it was difficult to determine who would be the youngest son due to peaceful life and large harem within palace; secondly, after death of emperor, older sons usually possessed strong power and resources that younger ones could hardly match! Thus almost every time there were changes in throne during middle period of Yuan dynasty produced either big or small disturbances greatly consuming national strength!
最后，不断变动的人事制度和权力结构也加剧了国家失衡。在中原王朝自古以来都在强化中央集权以保证内部稳定，但是在蒙古汗国盛行奴隶制下形成了不同模式。而到了汉族人统治下的中国，在这种基础上又有所变化，使得大臣能够获得无限信任并拥有无法被制约的大权，从而导致丞相可以共治天下甚至决定废立君主。
此外，由于官员认为贪污是正常行为，以至于中晚期的明室都认为官员贪污理所当然！他们把国家当做取之不尽，用之不竭宝库，一味索取却不进行任何治理！物价飞涨社会动荡百姓衣食难保，最终引发民变！
