The sudden death of the Xuande Emperor in January 1435 at age thirty-seven created an institutional crisis. His eight-year-old son Zhu Qizhen succeeded him as the first child emperor of the Ming Dynasty, and thus there was no precedence on how the state would be governed, and his grandmother
Grand Empress Dowager Zhang eventually emerged as leader of an informal regency that included three veteran grand secretaries - Yang Shiqi, Yang Rong, and Yang Pu (nicknamed the "Three Yangs") – who had served since the beginning of the Yongle reign, and three senior eunuch officials from the Directorate of Ceremonial, the highest office in the palace eunuch hierarchy. Wang Zhen joined this group in autumn 1435 when appointed to the Directorate at approximately age thirty-three, markedly younger than his colleagues but already influential through his close relationship with the new boy emperor, who viewed him as a mentor and confidant. In 1449, during the
Tumu Crisis campaign against the
Northern Yuan, he was killed, and the Ming emperor Zhu Qizhen was captured by
Oirat Mongols. According to some reports, Wang Zhen was killed by his own officers. == References ==
