AD 40 (XL) was a leap year starting on Friday of the Julian calendar. At the time, it was known as the Year of the Consulship of Augustus without colleague (or, less frequently, year 793 Ab urbe condita). The denomination AD 40 for this year has been used since the Early Middle Ages, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Events

By place

Roman Empire

• Emperor Caligula is consul without colleague.
• Caligula starts on a campaign to conquer Britain, which fails miserably. He declares himself victorious regardless.
• Noricum and Mauretania are incorporated into the Roman Empire.
• Caligula reforms the principatus into a Hellenistic Autocracy. He distributes honors carelessly, declares himself a god and orders that all the heads of the Greek deity statues be replaced by his. He also appoints his horse, Incitatus, a senator.
• Construction begins on the Pont du Gard aqueduct in Gallia Narbonensis (approximate date).[1]

Europe

• The Germanic Quadi tribe begin settling in present-day Moravia and Slovakia.

Parthia

• Vardanes I becomes king of Parthia, opposed by his brother Gotarzes II.

Vietnam

• The Vietnamese Trưng Sisters rebel against the rule of the Chinese Emperor Guang Wu of Han.

Religion

• Christianity comes to Egypt as a church is founded in Alexandria. Mark the Evangelist founds the Church of Alexandria as the first Patriarch (traditional date).
