Liu Bei's Imperial Bloodline
Was Liu Bei's pedigree or bloodline documented officially by the Han Imperial Court? While watching 2010's "Three Kingdoms" drama series, there is a scene where when Liu Bei kowtows before Emperor Xian. The emperor then asks Liu Bei his line of descent and Liu Bei answers, naming his father and grandfather. To verify, Emperor Xian orders one of his court officials to bring out a document and the official, to my surprise, reads out Liu Bei's line going all the way back to Emperor Jing of the Western Han Dynasty (a period of 300 years or about 20 generations), verifying his imperial bloodline. (Disclaimer: I do understand that this is a drama and things are embellished in dramas haha)
Now, this seemed quite incredulous to me initially because why would the Imperial Court keep record of a lowly peasant like Liu Bei? Liu Bei claimed to be a direct descendant of Liu Sheng, Prince of Zhongshan, who was a the son of Emperor Jing. Because Liu Sheng alone had over 100 sons, this genealogical branch exploded over the centuries. By the time Liu Bei was born, his relation to the sitting emperor was so distant that it conferred no practical nobility or wealth.
Additionally, under Han Dynasty succession laws, noble titles and estates were passed down to only one primary heir. The remaining sons and their descendants were gradually stripped of their noble status and demoted to commoner standing. Consequently, Liu Bei's family had completely lost their official court ties by the time of the Yellow Turban Rebellion.
Would this scene be accurate where the official just happens to have a record of Liu Bei's branch? Does the court have records of the other thousands of commoner Liu clansmen who also descend from the House of Han?
