sima yu

sima yu -lrb- 司馬遹 -rrb- -lrb- 278 -- 300 -rrb- , courtesy name xizu -lrb- 熙祖 -rrb- , formally crown prince minhuai -lrb- 愍懷太子 -rrb- was a chinese crown prince during the jin dynasty -lrb- 265-420 -rrb- .
sima yu 's father sima zhong was developmentally disabled , and before he , then crown prince , was to marry his wife jia nanfeng , his father emperor wu gave him one of his own concubines , consort xie jiu -lrb- 謝玖 -rrb- , so that consort xie could teach him how to have sexual relations .
while crown princess jia bore the crown prince four daughters , sima yu was his only son .
when sima yu was four years old , there was a fire in the palace , and emperor wu walked up a tower to observe it .
sima yu pulled him aside and said , `` at night , when something unusual like this happens , we should take precautions .
the light of the fire should not shine on the emperor . ''
emperor wu was surprised by this perceptive observation by a child , and praised the young prince as very much like his own grandfather sima yi .
this was part of the reason why emperor wu let crown prince zhong remain his heir .
in 289 , he created prince yu the prince of guangling .
after emperor wu died in 290 , crown prince zhong ascended the throne as emperor hui , and prince yu was created crown prince .
as crown prince yu grew in age , however , he lost some of the good reputation that he had as a child , as he disliked studying and spent much time on building projects and games .
empress jia , who had constantly been jealous of crown prince yu and consort xie , did not discourage this behavior , but in fact encouraged it to further damage crown prince yu 's reputation .
when crown prince yu 's staff would try to correct his ways , he would not listen to them .
he also would not listen to them with regard to their advice to maintain strong relations with empress jia 's family members .
empress jia 's mother guo huai -lrb- 郭槐 -rrb- had constantly advised empress jia to treat crown prince yu well , as her own son , and she advocated marrying a daughter of empress jia 's sister jia wu -lrb- 賈午 -rrb- to crown prince yu .
however , empress jia and jia wu opposed this , and instead married a daughter of the official wang yan -lrb- 王衍 -rrb- to crown prince yu .
-lrb- wang had two daughters , but empress jia had crown prince yu marry the less beautiful one and had her nephew jia mi marry the more beautiful one . -rrb-
after lady guo 's death , the relationship between empress jia and crown prince yu quickly deteriorated , as jia wu and another associate of empress jia , emperor wu 's concubine consort zhao can -lrb- 趙粲 -rrb- , provoked difficulties between them .
further , crown prince yu and jia mi never liked each other , and jia mi , as a result , also advised empress jia to depose crown prince yu .
in 299 , empress jia agreed and took action .
when crown prince yu was in the palace to make an official petition to have his ill son sima bin -lrb- 司馬彬 -rrb- created a prince , empress jia forced him to drink a large amount of wine and , once he was drunk , had him write out a statement in which he declared intention to murder the emperor and the empress and to take over as emperor .
empress jia presented the writing to the officials and initially wanted crown prince yu executed -- but after some resistance , she only had him deposed and reduced to status of a commoner .
crown prince yu 's mother consort xie was executed , as was his favorite concubine consort jiang jun -lrb- 蔣俊 , sima bin 's mother -rrb- .
wang yan divorced his daughter from the crown prince , who wrote an extant , lengthy letter to her explaining the incident through which empress jia framed him .
in 300 , under the advice of a prince she favored -- sima lun the prince of zhao , emperor wu 's granduncle -- empress jia decided to eliminate crown prince yu as a threat .
she sent assassins and had crown prince yu assassinated .
he was buried with honors due a prince -- under the title of prince of guanling .
sima lun 's intent was , however , to use this assassination as excuse to overthrow empress jia , and he did so later that year .
he had crown prince yu reburied with the honors due a crown prince and had him given the posthumous name minhuai .
he also welcomed crown princess wang back to the palace , along with crown prince yu 's surviving sons sima zang -lrb- 司馬臧 -rrb- -lrb- whom he had created crown prince -rrb- and sima shang -lrb- 司馬尚 -rrb- .
however , when sima lun then usurped the throne briefly in 301 , crown prince zang was killed .
after emperor hui 's restoration later that year , sima shang was created crown prince , but died in 302 , extinguishing crown prince yu 's line .
