Wang Mang 王莽, Emperor of Xin Dynasty

Wang Mang (Chinese: 王莽, c. 45 BC – 6 October 23 AD), courtesy name Jujun (巨君), was a Han Dynasty official who seized the throne from the Liu family and founded the Xin (or Hsin, meaning "renewed") Dynasty (新朝), ruling 9–23 AD. The Han dynasty was restored after his overthrow, and his rule marks the separation between the Western Han Dynasty (before Xin) and Eastern Han Dynasty (after Xin). Some historians have traditionally viewed Wang as a usurper, while others have portrayed him as a visionary and selfless social reformer. Though a learned Confucian scholar who sought to implement the harmonious society he saw in the classics, his efforts ended in chaos.

In October 23 AD, the capital Chang'an was attacked and the imperial palace ransacked. Wang Mang died in the battle.

The Han dynasty was reestablished in 25 AD when Liu Xiu (Emperor Guangwu) took the throne.
