Empress Zhangsun (長孫皇后, personal name unknown, presumably Wugou (無垢)) (15 March 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 a Chinese essayist and an empress of the Chinese Tang dynasty. She was the wife of Emperor Taizong and the mother of Emperor Gaozong. She was well educated, and her ancestors were of Xianbei ethnicity. Their original surname was Tuoba, later changed to Zhangsun. During her tenure as empress, she served as a loyal assistant and honest advisor to her husband, Emperor Taizong.
Background The future Empress Zhangsun was born on 15 March 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 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 613, she married Li Shimin, the second son of the general Li Yuan the Duke of Tang. Li Shimin was 15, and she was 13 (both ages are by East Asian reckoning).
It was written that the ancestors of Zhangsun family traced their origin to the Xianbei dynasty Northern Wei's founding emperor Emperor Taiwu of Northern Wei's 17th generation ancestor Tuoba Kuaili (拓跋儈立) — that their ancestor was Tuoba Kuali's third son, who took the surname Baba (拔拔), eventually changed to Zhangsun when Emperor Xiaowen of Northern Wei changed Xianbei surnames to Han surnames in 496.
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 Yang You 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, forming friendships with his concubines which she would use to cover up the mistakes of her husband and his faction.
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, on 4 September, 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 not wasteful, 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, and if there was a problem with the decision of Emperor Taizong about the administration, or for the officials and officers, she respectfully asked him to change the decision. Her influence over him was such that she interceded on behalf of condemned criminals and changed his harmful decisions with gentle counsel. One time, when Emperor Taizong got angry at a servant, she pretended to be angry as well and asked to personally interrogate them and hold them in custody; she then waited until his anger had subsided, and then begin to plead on their behalf, thus reducing improper punishments within the palace.From Volume 194 of Zizhi Tongjian [長孫皇后性仁孝儉素，好讀書，常與上從容商略古事，因而獻替，裨益弘多。上或以非罪譴怒宮人，後亦陽怒，請自推鞫，因命囚系，俟上怒息，徐為申理，由是宮壺之中，刑無枉濫。豫章公主早喪其母，後收養之，慈愛逾於所生。妃嬪以下有疾，後親撫視，輟己之藥膳以資之，宮中無不愛戴。]. It was said that whenever Emperor Taizong's concubines would be ill, she would personally visit them and reduce her own expenditures to treat them. When one of Emperor Taizong's concubines died giving birth to a daughter, Empress Zhangsun raised the daughter, Princess Yuzhang, as her own.
Emperor Taizong always loved Empress Zhangsun. After ascending the throne, he often showed more favor to the Empress family than allowed. Because of Empress Zhangsun, he granted extrajudicial favors to Zhangsun Anye, Zhangsun Shunde, and Zhangsun Chang for their illegal acts, and he lavishly gave gifts, grants and wealth to all empress relatives and friends to such an extent that many courtiers even the empress herself and some of her relatives objected to it. Emperor Taizong would at times try to discuss with empress matters of award and punishment and the suggestions of the officials on important matters and even confidential government information to see what she opined, but each time she refused to do so, stating that it was not her place to do so. She replied to him, "The crowing of hens in the morning is a sign of family trouble. As a woman, how dare I be informed of government affairs and give an opinion about it?"; However, Taizong's insistence forced her to tell him what she thought. 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:(文德皇后固请曰︰“妾备位椒房，家之贵宠极矣，诚不愿兄弟复执国政。吕、霍、上官，可为切骨之戒，幸陛下矜察！”上不听，卒用之。) Zizhi Tongjian, vol.192
I have the opportunity to be here in the palace, reaching the highest of honors. I do not wish to see my brothers and nephews wield power. What happened to the households of Han dynasty's Empress Lü Zhi, Huo Guang and Shangguan Jie are cruel examples of what might happen. I pray that Your Imperial Majesty will not make my brother chancellor.
Emperor Taizong initially disagreed and made Zhangsun Wuji chancellor anyway on 18 August 627,([贞观元年]秋，七月，壬子，以吏部尚书长孙无忌为右仆射。) Zizhi Tongjian, vol.192. Taizong's biographies in both Books of Tang recorded the same date of appointment. but with Zhangsun Wuji himself also repeatedly declining, Emperor Taizong relented on 13 February 628([贞观二年]春，正月，辛亥，右仆射长孙无忌罢。.....无忌自惧满盈，固求逊位，皇后又力为之请，上乃许之，以为开府仪同三司。) Zizhi Tongjian, vol.192 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 country-bumpkin!" Empress Zhangsun asked whom he was referring to, and he replied, "I am referring to Wei Zheng. He always finds 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.
