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.
Chinese sovereign
Hàn Guāng Wǔ Dì is equivalent to Dōng Hàn Guāng Wǔ Dì since he was the founder of the Eastern (dōng) Han Dynasty. All dōng (east)-xī (west), nán (south)-běi (north), qián (former)-hòu (later) conventions were invented only by past or present historiographers for denoting a new era of a dynasty. They were never used during that era.
