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.
Wang Mang
By this point, many other rebel leaders had become jealous of Liu Yan's capabilities, and while a good number of their men admired Liu Yan and wanted him to become the emperor of a newly declared Han Dynasty, they had other ideas. They found another local rebel leader, also of Han imperial descent, Liu Xuan, who was considered a weak personality, and requested that he be made emperor. Liu Yan initially opposed this move and instead suggested that Liu Xuan carry the title "Prince of Han" first (echoing the founder of the Han Dynasty, Emperor Gao). The other rebel leaders refused, and in early 23, Liu Xuan was proclaimed Gengshi Emperor. Liu Yan became prime minister.
