The Empress Dowager Xiaozhuang, (Chinese: 孝莊文皇后; Pinyin: Xiàozhuāngwén Huánghòu; Manchu: Hiyoošungga Ambalinggū Genggiyenšu Hūwanghu; March 28, 1613 - January 27, 1688), known for the majority of her life under the title "Grand Empress Dowager", was the mother of the Shunzhi Emperor and the grandmother of the Kangxi Emperor during the Qing Dynasty in China. She wielded significant influence over the Qing court during the rule of her son and grandson. Known for her wisdom and political ability, Xiaozhuang has become a largely respected figure in Chinese history, strictly in contrast to the despotic reputation of Empress Dowager Cixi.
Empress Xiao Zhuang Wen was a daughter of a prince of Borjigit clan of the Khorchin Mongols, Prince Jaisang, and thus was a descendant of Genghis Khan. Her given name was Bumbutai (Chinese: 布木布泰; pinyin: Bùmùbùtài).
