Year 18 (XVIII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Augustus and Caesar (or, less frequently, year 771 Ab urbe condita). The denomination 18 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Roman Empire[edit]




  • After a flooding of the Yellow River farmers are forced to rebel. Emperor Wang Mang reacts by sending an army (some 100,000 men) against the agrarian rebels. The rebel leaders, concerned that during battle it would become impossible to tell friend from foe, order that their men color their eyebrows red – and this is where the name Chimei ("The Red Eyebrows") comes from.
