雍正帝
Yuntang (17 October 1683 – 22 September 1726), born Yintang, was a Manchu prince of the Qing dynasty. He was the ninth son of the Kangxi Emperor and an ally of his eighth brother Yunsi, who was the main rival to their fourth brother Yinzhen in the power struggle over the succession. In 1722, Yinzhen succeeded their father and became historically known as the Yongzheng Emperor, after which he started purging his former rivals. In 1725, the Yongzheng Emperor stripped Yuntang off his "beizi" title, banished him from the Aisin Gioro clan, and imprisoned him in Baoding. Yuntang died under mysterious circumstances later. In 1778, the Qianlong Emperor, who succeeded the Yongzheng Emperor, posthumously rehabilitated Yuntang and restored him to the Aisin Gioro clan.
