Prince Rui of the First Rank, or simply Prince Rui, was the title of a princely peerage used in China during the Manchu-led Qing dynasty (1644–1912). As the Prince Rui peerage was not awarded "iron-cap" status, this meant that each successive bearer of the title would normally start off with a title downgraded by one rank vis-à-vis that held by his predecessor. However, the title would generally not be downgraded to any lower than a feng'en fuguo gong except under special circumstances.

The Jiaqing Emperor, also known by his temple name Emperor Renzong of Qing, personal name Yongyan, was the sixth emperor of the Manchu-led Qing dynasty and the fifth Qing emperor to rule over China proper. He was the 15th son of the Qianlong Emperor. During his reign, he prosecuted Heshen, the corrupt favorite of his father and attempted to restore order within the empire while curbing the smuggling of opium into China.
