AD 8 in the context of Marcus Vinicius (consul 19 BC)

⭐ Core Definition: AD 8

The 0s began on January 1, AD 1 and ended on December 31, AD 9, covering the first nine years of the Common Era.

In Europe, the 0s saw the continuation of conflict between the Roman Empire and Germanic tribes in the Early Imperial campaigns in Germania. Vinicius, Tiberius and Varus led Roman forces in multiple punitive campaigns, before sustaining a major defeat at the hands of Arminius in the Battle of the Teutoburg Forest. Concurrently, the Roman Empire fought the Bellum Batonianum against a rebelling alliance of native peoples led by Bato the Daesitiate in Illyricum, which was suppressed in AD 9. A conflict also took place in Korea, where Daeso, King of Dongbuyeo invaded Goguryeo with a 50,000-man army in AD 6. He was forced to retreat when heavy snow began to fall, stopping the conflict until the next decade. In China, the last ruler of the Chinese Western Han dynasty (Ruzi Ying) was deposed, allowing Wang Mang to establish the Xin dynasty.

AD 8 in the context of Proleptic Julian calendar

The proleptic Julian calendar is produced by extending the Julian calendar backwards to dates preceding AD 8 when the quadrennial leap year stabilized. The leap years that were actually observed between the implementation of the Julian calendar in 45 BC and AD 8 were erratic (see the Julian calendar article for details).

A calendar obtained by extension earlier in time than its invention or implementation is called the "proleptic" version of the calendar. Likewise, the proleptic Gregorian calendar is occasionally used to specify dates before the introduction of the Gregorian calendar in 1582. Because the Julian calendar was used before that time, one must explicitly state that a given quoted date is based on the proleptic Gregorian calendar if that is the case.
