Prince Gong (peerage)

The first bearer of the Prince Gong title in the first family line was Changning (1657–1703), the fifth son of the Shunzhi Emperor.

As the Prince Gong 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 Prince Gong title in the second family line was Yixin (1833–1898), the sixth son of the Daoguang Emperor.

In 1872, during the reign of the Tongzhi Emperor, the second Prince Gong peerage, unlike the earlier one, was granted "iron-cap" status.
