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.
Jia Xu
In 220, Cao Pi forced Emperor Xian to abdicate the throne to him, thus ending the Han dynasty. He then established the state of Wei with himself as its first emperor. After ascending the throne, Cao Pi appointed Jia Xu as Grand Commandant (太尉) and promoted him from a Marquis of a Chief Village to the Marquis of Weishou District (魏壽鄉侯), with a marquisate of 800 taxable households. Jia Xu's promotion was allegedly an expression of gratitude from Cao Pi, who wanted to thank him for helping him seize the succession years ago. Sun Quan laughed when he heard that Cao Pi had appointed Jia Xu as his Grand Commandant.
