Chinese emperors family tree (early)
Emperor Xian, the last emperor of the Han dynasty, was a descendant of the first emperor Liu Bang. Lasting for over 400 years (the first to last for more than a century), the Han Dynasty is regarded as one of the golden ages of Chinese history. The Han Dynasty was interrupted by the reign of the usurper Wang Mang, who declared the Xin dynasty (9–23 AD); on this basis, the Han Dynasty is generally divided into the Western Han (206 BC – 9 AD and 23–25 AD) and the Eastern Han (25–220 AD). The rulers of the Shu Han, one of the three successor states to the Han Dynasty during the Three Kingdoms period, were descended from the Han imperial family, and considered themselves a continuation of the Han Dynasty; they are included below.
Xi Zuochi
Even the work's title, naming the Han and Jin dynasties without mention of the intervening Wei, is indicative of its primary thrust. The annals began with Emperor Guangwu of Han, restorer of the dynasty and founding emperor of the Eastern (or Later) Han, and continued through to the time of Emperor Min of Jin, final emperor of the Western Jin (i.e. years CE 25–317). Although his primary goal was to argue that ritual abdication was insufficient to achieve a legitimate mandate, Xi Zuochi's aims had the secondary effect of legitimating Liu Bei's Shu Han as the legitimate successor to the Han dynasty, which he displayed by employing the Shu Han calendar, going so far as to use dynastic founder Emperor Wu of Jin's taboo personal name in recording the events of Liu Shan's final regnal year. Late in life, in his final memorial to the throne, Xi Zuochi laid bare his rationale and method behind delegitimating Wei while conducting the balancing act of considering the Jin dynasty still legitimate.
