开端 终结 在位 945年 945年 文经 945年 945年 

　　945年，段思平的儿子段思英即位，在位仅一年，就因权位之争被废为僧。
　　
　　据说段思英是个极其荒淫昏庸之人，“淫戏无度”，结果在位一年，就被段思平之弟段思良伙同相国董迦罗废除，段思良自立为帝。，《滇史》称：“思平一子思英不肖，心欲废之，左右诸臣谏阻。及将死，谓弟思良曰：吾子非承大业，尔宜善继吾绪。思良泣受命。”好像有点类似后来赵宋所谓的“金匮之盟”中“国当立长君”的味道。其实，段思英被废为僧，属于大理国统治集团内部各种势力争斗中，一次典型的夺宫之变。
　　
　　据《滇史》记载，“思英性暴戾，居丧淫戏无度，多变易文德年制度”。这就是说，段思英被废，是因为三个原因：性情暴戾；淫戏无度；变易旧制。据云南省社科院历史研究所研究员段玉明所著的《大理国史》所述，段思英的性情是否暴戾，除《滇史》外，其它各史均无记载；至于淫戏无度是否到了必欲废之的地步，也有待研究。因此，性情暴戾、淫戏无度，应该都不是段思英被废的主要原因，倒是“变易旧制”这第三个原因颇耐人寻味。段思英将其母杨桂仙封为“榆城宣惠圣国母”，不是一个单纯的尊母行为，而是一个推崇杨氏势力的信号，这显然与段思平立国时，以董姓为重要依靠的方针有悖，所谓变易旧制，应该就是指这一变化。董氏为滇中旧族，是段思平改朝换代时的主要依靠力量，董氏的代表人物董迦罗乃段思平的军师，与段思英之叔段思良关系不一般。大理国建立后，董迦罗顺理成章地成了大权在握的相国。段思平死后，段思英企图抬高杨氏势力的地位，很可能是因为受到了董氏势力的威逼，而段思英的所作所为，势必引起以董氏势力为首的各政治势力的不满，在这个过程中，董迦罗自然与和他相交甚深的段思良结成了利益联盟。
　　
　　946年，在位仅有一年光景的段思英被其叔段思良与相国董迦罗废而为僧，自认开国有功的段思良即位。从此以后，大理国的王位继承上思平、思良两支系更替的争夺，埋下激烈的权力争斗的伏线。段思英被废为僧后，在大理崇圣寺修行。段思英是被废为僧的首位国王，在位期间用过一个年号，文经(945)，故史称大理文经帝。

　　Duan Ying said to be a very dissolute stupid person, "lewd show excessive", the result his year, he was Duan Duan Ping's younger brother, Dong Xiang-Guo Liang together with Galois repeal, Duan good self as the Emperor. , "Dian history", said: "Si Ping-Zisi British and foolishness, waste of hearts desire, so Zhu Chen dissuade. And will die thinking that the good brother said: Wu Zi cause of non-commitment, Seoul should continue my good thread. Si-liang ordered weeping. "seems somewhat similar to Zhao Song was called" Golden Covenant "in the" country when long-Jun Li "flavor. In fact, Duan Ying was spent as a monk, belonging to Dali various forces fighting within the ruling in a typical house of the change wins.
　　According to "History of Yunnan" records, "the British think of violent, pornographic mourning unrestrained play, changing the system easy to Bonaventure years." This means that, Duan Ying was spent because of three reasons: violent temper; pornographic movie excessive; Variation of the old system. According to the history of Yunnan Academy of Social Sciences researcher Yu-Ming Duan book "Dali and national history," above, Duan British temperament is violent, in addition to "History of Yunnan", the other the history of no records; As for the pornographic movie is excessive to the point of waste which must also be studied. Therefore, the nature violent, pornographic movie excessive, should not think the British section of the main reasons being spent, since the "Variation of the old system," the third reason is quite interesting. Duan Ying Gui Xian will be his mother called "Elm City xuanhui Holy mother of the country" is not a simple respect for female behavior, but a respected Young's power signal, which is obviously Duan Siping founding, the names of directors and the importance of relying on contrary to the principle of the so-called Variation of the old system is that the change should be. Yunnan Dong for the old family, is regime change Duan Siping mainly depend on when the power is Galois Dong Dong representatives of the army, division, Duan Siping, and Duan United Kingdom of Shu Duan good relations are not general. Dali created, Dong Galois became a matter of course with the country in power. Duan Ping died, Duan Yang forces in the British attempt to elevate the status, probably because of coercion by the John Tung forces, while the actions of the British section of thinking will inevitably lead to forces led by the John Tung various political forces dissatisfaction in the process, directors, and his natural and Galois deep segments intersect to form a coalition of interests thought good.
