长孙无忌
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 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.
