The Xin Dynasty was a short-lived dynasty in ancient China that lasted from 9 to 23 AD. It was established by Wang Mang, a former regent who seized power from the Han Dynasty. The Xin Dynasty is known for its attempts to implement radical reforms, including land redistribution and currency changes, aimed at addressing social inequalities. However, these reforms faced significant resistance and led to widespread unrest. The dynasty ultimately collapsed due to internal strife and rebellion, notably the Red Eyebrows Rebellion. Following its fall, the Eastern Han Dynasty was restored, marking the end of the Xin Dynasty's brief rule.
