"Princess of Great Peace", personal name unknown, possibly Li Lingyue (李令月) (after 662 – 2 August 713) was a royal princess and prominent political figure of the Tang dynasty and her mother Wu Zetian's Zhou dynasty. She was the youngest daughter of Wu Zetian and Emperor Gaozong and was influential during the reigns of her mother and her elder brothers Emperor Zhongzong and Emperor Ruizong (both of whom reigned twice), particularly during Emperor Ruizong's second reign, when for three years until her death, she was the real power behind the throne. She is the most famous and influential princess of the Tang dynasty and possibly in the whole history of China thanks to her power, ability and ambition. She was involved in political difficulties and developments during the reigns of her mother and brothers. Indeed, after the coup against Empress Dowager Wei, she became the real ruler of Tang. During the reign of Emperor Ruizong, she was not restricted by anything, the emperor issued rulings based on her views and the courtiers and the military flattered her and majority from every civil and military class joined her faction, so her power exceeded that of the emperor.
