Empress Dugu Qieluo

Dugu Qieluo or Dugu Jialuo, formally Empress Wenxian (文獻皇后), was an empress of the Sui dynasty of China. She was the wife of Emperor Wen, who, on account of his love and respect for her, as well as an oath they made while they were young, did not have any concubines for at least most of their marriage, an extreme rarity among Chinese emperors. She also bore him all his children. However, she was domineering, ruthless, exceedingly powerful, and influential during her husband's reign, and assisted him in running the empire.
