Feng'en fuguo gong (Manchu: ᡴᡝᠰᡳ ᠪᡝᡨᡠᠸᠠᡴᡳᠶᠠᡵᠠᡤᡠᡵᡠᠨ ᡩᡝᠠᡳᠰᡳᠯᠠᡵᠠᡤᡠᠩ|v=kesi-be tuwakiyara gurun-be aisilara gung, Mongolian: Хишигийг сахих улсад туслагч гүн), translated as "Grace Bulwark Duke" or "Duke Who Assists to the State by the Grace" or "State Duke of the Second Rank", was one of the royal and noble titles of the Qing dynasty. A title was created in 1653 by division of the zhenguo gong title into two ranks following the criterion of sharing Eight Privileges.[1] The title was the eighth highest rank in the extended system of ranks and the fifth inheritable rank.[2]
The title was the lowest possible to inherit in the peerage of the second rank except of special circumstances.[3] The title could also convey a honorifical name consisting of two characters.[4] The title could be made perpetually inheritable in case of abolition of the peerage.[5]
The title could be granted to the son of Feng'en zhenguo gong born to State Duchess of the First Rank.[6]
Princess consort was styled as "feng'en fuguo gong furen" (奉恩輔國公夫人), which translates to "State Duchess of the Second Rank". Often the title was replaced by the term Primary Wife (嫡妻).
Son of feng'en fuguo gong was granted a title of third class bulwark general.[7] As the title was the last possible for the peerage, the right to inherit the title of Duke of the Second Rank was reserved to the sons born to primary consorts. However, the title son inherited could convey different honorifical name in case when father's title had been given honorifical name. De facto sons born to secondary consorts of the feng'en fuguo duke received various official positions and became unranked imperial clansmen.[8]
Daughter born to primary consort of feng'en zhenguo duke was granted a title of Lady of the Third Rank (乡君). Daughters born to secondary consort of feng'en fuguo gong were granted a title of sixth rank clanswoman.[9]
The allowance of grace bulwark duke reached 500 taels of silver and 500 hu of rice.[10]
The basic allotment of xiangjun reached 40 taels and 40 hu of rice. As most of the ladies of the third rank were married off, the allowance included 40 taels and 5 rolls of fabrics. Xiangjun was allowed to have 4 personal maids and 2 bodyguards.[13]
