Emperor Yingzong of Ming (29 November 1427 – 23 February 1464), personal name Zhu Qizhen, was the sixth and eighth emperor of the Ming dynasty. He ruled as the Zhengtong Emperor from 1435 to 1449, and as the Tianshun Emperor from 1457 to 1464.
Emperor Yingzong was the eldest son and successor of the Xuande Emperor. After ascending the throne, he adopted the era name Zhengtong, which means "right governance". During his first reign, the empire was at its height of prosperity and power. As the first child emperor of the Ming dynasty, his rule was heavily influenced by high dignitaries at court. Initially, his grandmother, Grand Empress Dowager Zhang, along with the "Three Yangs" (Yang Shiqi, Yang Rong, and Yang Pu), held the highest positions of power.
