Prince Yu (愉)

Prince Yu of the Second Rank, or simply Prince Yu, was the title of a princely peerage used in China during the Manchu-led Qing dynasty (1644–1912). As the Prince Yu 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 first bearer of the title was Yunxu (允禑; 1693–1731), the 15th son of the Kangxi Emperor. In 1730, Yunxu was granted the title "Prince Yu of the Second Rank" by the Qianlong Emperor. The title was passed down over seven generations and held by seven persons.
