Wu Zetian entered the palace of Emperor Taizong at fourteen as a low-ranking consort, according to the Old Book of Tang. Taizong was the father of Li Zhi, later Emperor Gaozong. When Taizong died, Wu left the palace and entered Ganye Temple as a Buddhist nun. Gaozong later saw her there, recalled her to court and appointed her Zhaoyi, a senior consort. She first served the father, then returned to court under his son.
Wu became Gaozong’s empress in 655. These changes in rank placed her within the centre of Tang court life, where succession, family ties and access to the emperor shaped political influence.
