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 Wu of Han
The personal name of Emperor Wu was Liu Che (刘彻). The use of "Han" (汉) in referring to emperor Wu is a reference to the Han dynasty of which he was a part. His family name is "Liu"; the ruling family or clan of the Han dynasty shared the family name of "Liu", the family name of Liu Bang, the founding father of the Han dynasty. The character "Di" (帝) is a title: this is the Chinese word which in imperial history of China means "emperor". The character "Wu" (武) literally means "martial" or "warlike", but is also related to the concept of a particular divinity in the historical Chinese religious pantheon existing at that time. Combined, "Wu" plus "di" makes the name "Wudi", the emperor's posthumous name used for historical and for religious purposes, such as offering him posthumous honours at his tomb.
