As the Prince An 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 Abatai (1589–1646), the seventh son of Nurhaci, the founder of the Qing dynasty.
The title was renamed to "Prince An of the Second Rank" in 1651 when it was passed down to Abatai's fourth son, Yolo (1625–1689).
However, in 1778, the Qianlong Emperor considered Abatai and Yolo's past contributions to the Qing Empire, and decided to restore the Prince An peerage as a feng'en fuguo gong title – the lowest possible grade for a princely peerage.
