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.
Names of China
The name "Han" (/; ) derives from the Han dynasty (206 BC–220 AD), who presided over China's first "golden age". The Han dynasty collapsed in 220 and was followed by a long period of disorder, including Three Kingdoms, Sixteen Kingdoms, and Southern and Northern Dynasties periods. During these periods, various non-Chinese ethnic groups invaded from the north and conquered areas of North China, which they held for several centuries. It was during this period that people began to use the term "Han" to refer to the natives of North China, who (unlike the invaders) were the descendants of the subjects of the Han dynasty.
