Wu Shun (武顺) (623-665, common era) was the Lady of Han (韩国夫人) during the Tang Dynasty and the older sister of Wu Zetian. The Lady of Han was an honorable title for relatives of the Emperor and Empress. Wu Shun was allegedly the mother of Li Xian, the crown prince, and the rumors eventually led to his demise. In all likelihood, her bloodthirsty and power-hungry sister Empress Wu, who had become a full-fledged power behind the throne after January 665, ordered her poisoning.
