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.
Southward expansion of the Han dynasty
Supported by the Han military, Minyue was established in 202 BC and Eastern Ou in 192 BC after the fall of the Qin dynasty. Zhao Tuo, a former Chinese commander of the Qin, established Nanyue in 208 BC after the death of the emperor Qin Shi Huang. Emperor Gaozu, first emperor of the Han dynasty, approved Zhao Tuo's new title as king. Zhao was born in the city of Zhending in Central China, and the ruling class of the new kingdom was composed of Chinese officials from the former Qin dynasty. In 180 BC, Zhao offered to submit as a vassal state and the Han accepted, a decision partly based on his family's northern Chinese ancestry.
