Empress Zhangsun Empress Zhangsun ( 長孫皇后 , personal name unknown ) ( 601 – 28 July 636 ) , formally Empress Wendeshunsheng ( 文德順聖皇后 , literally " the civil , virtuous , serene , and holy empress " ) or , in short , Empress Wende ( 文德皇后 ) , was an empress of the Chinese dynasty Tang Dynasty . She was the wife of Emperor Taizong and the mother of Emperor Gaozong . She was of Xianbei origin and well educated . Background . The future Empress Zhangsun was born in 601 . Her father was the Sui Dynasty general Zhangsun Sheng ( 長孫晟 ) , and her mother was Zhangsun Sheng ' s wife Lady Gao , the daughter of the official Gao Jingde ( 高敬德 ) . She had at least four older brothers — Zhangsun Sheng ' s oldest son Zhangsun Xingbu ( 長孫行布 , who was killed in 604 while resisting the rebellion of Emperor Yang of Sui ' s brother Yang Liang the Prince of Han ) , Zhangsun Heng ' an ( 長孫恆安 ) , Zhangsun Anye ( 長孫安業 ) , and Zhangsun Wuji . ( Zhangsun Wuji was also born of Lady Gao , while Zhangsun Anye was not ; who Zhangsun Xingbu ' s and Zhangsun Heng ' an ' s mothers were was not recorded in history . ) Zhangsun Sheng died in 609 , and Zhangsun Anye , instead of raising his younger brother and sister , expelled them , as well as his stepmother Lady Gao , from the Zhangsun household and sent them back to Lady Gao ' s brother Gao Shilian , and Gao Shilian raised them . The future Empress Zhangsun was said to be studious and proper in her actions . In 614 , she married Li Shimin , the second son of the general Li Yuan the Duke of Tang . ( Li Shimin was 15 , and she was 13 . ) As Princess of Qin and crown princess . In 617 , Li Yuan , aided by Li Shimin and his older brother Li Jiancheng , among others , rebelled at Taiyuan ( 太原 , in modern Taiyuan , Shanxi ) , and later that year captured the capital Chang ' an , declaring Emperor Yang ' s grandson Yang You the Prince of Dai emperor ( as Emperor Gong ) . In 618 , after news arrived that Emperor Yang had been killed in a coup at Jiangdu ( 江都 , in modern Yangzhou , Jiangsu ) led by the general Yuwen Huaji , Li Yuan had Emperor Gong yield the throne to him , thus establishing the Tang Dynasty . Li Yuan became the first Tang ruler , Emperor Gaozu . He appointed his son , Li Shimin , as the Prince of Qin , his wife as the Princess of Qin . The couple would eventually have three sons – Li Chengqian , Li Tai , and Li Zhi – and at least three daughters , who were later named the Princesses Changle , Jinyang , and Xincheng . Li Shimin was Tang ' s most capable general in its campaigns to reunite China following Sui ' s collapse , defeating the major enemies Xue Rengao the Emperor of Qin , Liu Wuzhou the Dingyang Khan , Wang Shichong the Emperor of Zheng , and Dou Jiande the Prince of Xia . In doing so , he overshadowed his older brother Li Jiancheng , the crown prince . The brothers developed an intense rivalry . Princess Zhangsun was said to serve her father - in - law Emperor Gaozu carefully while trying to reduce the adversarial nature of the brothers ' relationship ( unsuccessfully ) . Sources state that in 626 , the crown prince Li Jiancheng and another brother , Li Yuanji the Prince of Qi , who supported Li Jiancheng , set out to ambush the rising Li Shimin . But Li Shimin heard about this trap , and organized a counter - coup , walking into the trap with several of his own most trusted and skilled soldiers . When Li Shimin mobilized his personal troops within his mansion , and as he did so , Princess Zhangsun was said to have personally made an appearance before the troops to encourage them . Her brother Zhangsun Wuji was one of Li Shimin ' s major strategists in this matter . Li Shimin was able to counter Li Jiancheng and Li Yuanji at Xuanwu Gate and kill them , and then essentially forced Emperor Gaozu to appoint him crown prince . Princess Zhangsun was accordingly named crown princess . Two months later , Emperor Gaozu yielded the throne to Li Shimin , who took the throne as Emperor Taizong . Princess Zhangsun , consequently , became empress , and their oldest son , Li Chengqian , became crown prince . As empress . As empress , Empress Zhangsun was said to be frugal and humble , taking only the supplies that she needed without living luxuriously . When Li Chengqian ' s wet nurse the Lady Sui ' an stated that his palace lacked sufficient goods and requested more , she replied , " All a crown prince should worry about is not having enough virtues or enough fame . Why worry about not having enough goods ? " It was also said that she rarely got angry with the ladies in waiting and eunuchs who served her . She often gave Emperor Taizong examples from history to inspire him to rule better . At times , if Emperor Taizong got angry at the ladies in waiting or eunuchs for no reason , she would pretend to be angry as well and ask to personally interrogate them and hold them in custody ; she would then wait until his anger had subsided , and then begin to plead on their behalf , thus reducing improper punishments within the palace . It was said that whenever Emperor Taizong ' s concubines or ladies in waiting would be ill , she would personally visit them and reduce her own expenditures to treat them . Emperor Taizong would at times try to discuss with her matters of award and punishment to see what she opined , but each time she refused to do so , stating that it was not her place to do so . As her brother Zhangsun Wuji was a major strategist who contributed much to his victory over Li Jiancheng , he wanted to make Zhangsun Wuji a chancellor , and Empress Zhangsun declined on Zhangsun Wuji ' s behalf , stating : Emperor Taizong initially disagreed and made Zhangsun Wuji chancellor anyway in fall 627 , but with Zhangsun Wuji himself also repeatedly declining , Emperor Taizong relented in spring 628 and removed Zhangsun Wuji from the chancellor position . Also in 627 , Empress Zhangsun ' s other brother Zhangsun Anye was implicated in a treasonous plot , along with the generals Li Xiaochang ( 李孝常 ) , Liu Deyu ( 劉德裕 ) , and Yuan Hongshan ( 元弘善 ) . Initially , Zhangsun Anye , like the other conspirators , were to be put to death , but Empress Zhangsun interceded on his behalf , stating that even though Zhangsun Anye deserved death , the people would have thought that she was retaliating for his ill treatment of her and Zhangsun Wuji when they were little . Emperor Taizong agreed and spared Zhangsun Anye , only exiling him to Xi Prefecture ( 巂州 , roughly modern Liangshan Yi Autonomous Prefecture , Sichuan ) . In 632 , Emperor Taizong was about to marry the Princess Changle to Zhangsun Wuji ' s son Zhangsun Chong ( 長孫沖 ) . As the princess was born of Empress Zhangsun and was his favorite daughter , Emperor Taizong ordered that her dowry had to exceed that for his sister , the Princess Yongjia . The chancellor Wei Zheng advised against it , pointing out that this was contrary to Emperor Ming of Han ' s observation that his sons should not be as honored as his brothers . Emperor Taizong agreed and also informed Empress Zhangsun , who was greatly impressed with Wei ' s honest advice , and therefore , after receiving permission from Emperor Taizong , she had her eunuchs send rewards of money and silk to Wei , praising him for his honesty . On another occasion , after Emperor Taizong returned from an imperial gathering , he was angry and yelled , " Let me find a chance to kill this red - neck ! " Empress Zhangsun asked whom he was referring to , and he replied , " I am referring to Wei Zheng . He always find a way to insult me in front of everyone in the imperial hall ! " Empress Zhangsun retreated to her bedchambers and put on the official empress gown ; standing solemnly , she prepared to bow to Emperor Taizong . He was surprised , and asked her what the reason was . She responded , " I have heard that only a most able emperor will have subordinates who have integrity . Wei shows this much integrity because you are an able emperor . How can I not congratulate you ? " Emperor Taizong ' s anger turned to happiness , and he did not punish Wei . Later that year , on an occasion when Emperor Taizong and she personally visited Emperor Gaozu ( who had then taken the title of " Taishang Huang " ( retired emperor ) ) at his Da ' an Palace ( 大安宮 ) , they personally served a feast to him . Emperor Taizong , for several years , had often suffered from severe illnesses , and Empress Zhangsun often attended to him day and night , carrying poison within her belt and resolving to commit suicide if the emperor should die . Empress Zhangsun herself was said to suffer from severe asthma , and her conditions were exacerbated in 634 when she was ill , but nevertheless attended to Emperor Taizong when he was forced to wake up in the middle of the night and put on armor and weapons due to an emergency report by his brother - in - law , Chai Shao ( 柴紹 ) the Duke of Qiao . By 636 , her conditions were severe , and Li Chengqian suggested to her that , as the doctors appeared to have done everything they could , Emperor Taizong declare a general pardon and encourage commoners to become Buddhist or Taoist monks , to try to gain divine favor . Empress Zhangsun , knowing that Emperor Taizong had long disapproved of Buddhism and Taoism and herself believing over use of pardons to be improper , refused . Li Chengqian instead told the idea to the chancellor Fang Xuanling , who reported it to Emperor Taizong . Emperor Taizong considered issuing a general pardon , but Empress Zhangsun again refused . As she came close to death ( at a time that Fang had drawn anger from Emperor Taizong and was temporarily relieved of his post and returned to his mansion ) , she bid Emperor Taizong goodbye with these words ; She died in 636 . After she died , the palace authorities submitted Empress Zhangsun ' s writings — a 30 - volume work titled " Examples for Women " ( 女則 , " Nü Ze " ) , and a commentary criticizing Han Dynasty ' s Empress Ma – to Emperor Taizong . When Emperor Taizong read her works , he was greatly saddened , and he stated : He summoned Fang back to his chancellor position , and then he buried her with honors due an empress , but reduced the expenditures to the extent possible , as she wished . He himself would eventually be buried at the same tomb , after his death in 649 . Issue . Empress Zhangsun produced seven children with Emperor Taizong :
