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.
Emperor Cheng of Han
Emperor Cheng of Han (51 BC – 17 April 7 BC) was an emperor of the Chinese Han Dynasty ruling from 33 until 7 BC. He succeeded his father Emperor Yuan of Han. Under Emperor Cheng, the Han dynasty continued its slide into disintegration while the emperor's maternal relatives of the Wang clan continued their slow grip on power and on governmental affairs as promoted by the previous emperor. Corruptions and greedy officials continued to plague the government and as a result rebellions broke out throughout the country. Emperor Cheng died childless after a reign of 26 years (both of his sons by concubines died in infancy, one of them starved to death) and was succeeded by his nephew Emperor Ai of Han.
