　　945年，段思平的兒子段思英即位，在位僅一年，就因權位之爭被廢為僧。
　　
　　據說段思英是個極其荒淫昏庸之人，“淫戲無度”，結果在位一年，就被段思平之弟段思良夥同相國董迦羅廢除，段思良自立為帝。，《滇史》稱：“思平一子思英不肖，心欲廢之，左右諸臣諫阻。及將死，謂弟思良曰：吾子非承大業，爾宜善繼吾緒。思良泣受命。”好像有點類似後來趙宋所謂的“金匱之盟”中“國當立長君”的味道。其實，段思英被廢為僧，屬於大理國統治集團內部各種勢力爭鬥中，一次典型的奪宮之變。
　　
　　據《滇史》記載，“思英性暴戾，居喪淫戲無度，多變易文德年制度”。這就是說，段思英被廢，是因為三個原因：性情暴戾；淫戲無度；變易舊製。據雲南省社科院歷史研究所研究員段玉明所著的《大理國史》所述，段思英的性情是否暴戾，除《滇史》外，其它各史均無記載；至於淫戲無度是否到了必欲廢之的地步，也有待研究。因此，性情暴戾、淫戲無度，應該都不是段思英被廢的主要原因，倒是“變易舊製”這第三個原因頗耐人尋味。段思英將其母楊桂仙封為“榆城宣惠聖國母”，不是一個單純的尊母行為，而是一個推崇楊氏勢力的信號，這顯然與段思平立國時，以董姓為重要依靠的方針有悖，所謂變易舊製，應該就是指這一變化。董氏為滇中舊族，是段思平改朝換代時的主要依靠力量，董氏的代表人物董迦羅乃段思平的軍師，與段思英之叔段思良關係不一般。大理國建立後，董迦羅順理成章地成了大權在握的相國。段思平死後，段思英企圖擡高楊氏勢力的地位，很可能是因為受到了董氏勢力的威逼，而段思英的所作所為，勢必引起以董氏勢力為首的各政治勢力的不滿，在這個過程中，董迦羅自然與和他相交甚深的段思良結成了利益聯盟。
　　
　　946年，在位僅有一年光景的段思英被其叔段思良與相國董迦羅廢而為僧，自認開國有功的段思良即位。從此以後，大理國的王位繼承上思平、思良兩支係更替的爭奪，埋下激烈的權力爭鬥的伏綫。段思英被廢為僧後，在大理崇聖寺修行。段思英是被廢為僧的首位國王，在位期間用過一個年號，文經(945)，故史稱大理文經帝。

　　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.
