Book of the Later Han

The book was compiled by Fan Ye and others in the 5th century during the Liu Song dynasty, using a number of earlier histories and documents as sources.

In 23 CE, Han dynasty official Wang Mang was overthrown by a peasants' revolt known as the Red Eyebrows.

Fan Ye used earlier histories, including accounts by Sima Qian and Ban Gu, along with many others (some had similar names, such as the Han Records of the Eastern Lodge by various contemporaries throughout the 2nd century, and the Records of Later Han by Yuan Hong from the 4th century), most of which did not survive intact.

The section on the Treatise on the Western Regions was based on a report composed by Ban Yong (with a few later additions) and presented to Emperor An of Han in around 125.

It contains a few references to events occurring after the death of Emperor An, including a brief account of the arrival of the first official envoys from Rome in 166.
