Jingtai Emperor's change of heirs apparent

The change of heirs apparent of 1452 was a major political event in the Ming dynasty of China. It refers to the attempt by the Jingtai Emperor to depose his nephew, Zhu Jianshen, and install his own son, Zhu Jianji, as heir to the throne. This took place after the Tumu Crisis of 1449, during which the Jingtai Emperor ascended the throne following the capture of his brother, Emperor Yingzong, by the Mongol forces. To achieve his goal, the Emperor resorted to various means, including widespread bribery of high-ranking officials and the use of force against those who opposed him. An emperor using such methods to secure the succession for his son was a rare and notable occurrence in Chinese history.

In 1454, Zhu Jianji died, having held the position of heir for only a year. Although some ministers suggested restoring Zhu Jianshen as heir, the Emperor never reinstated him. Three years later, the Jingtai Emperor was overthrown in a palace coup, and Emperor Yingzong regained the throne, with Zhu Jianshen once again designated as heir.
