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.
Shu Han
Cao Cao died in 220 and was succeeded by his son, Cao Pi, who forced the last Han ruler, Emperor Xian, to abdicate the throne in his favour. Cao Pi then established the state of Cao Wei and declared himself emperor. Liu Bei contested Cao Pi's claim to the throne and proclaimed himself "Emperor of Shu Han" in 221. Although Liu Bei is widely seen as the founder of Shu, he never claimed to be the founder of a new dynasty; rather, he viewed Shu as a continuation of the fallen Han dynasty.
