The year 40 AD (written as XL in Roman numerals) was a leap year starting on Friday in the Julian calendar. Back then, people knew it as the Year of the Consulship of Augustus without colleague. This means that the Roman Emperor Augustus was the only consul that year, which was unusual.

Two new areas, Noricum and Mauretania, became part of the Roman Empire.
Emperor Caligula changed the way the Roman government worked, making himself even more powerful, like an absolute ruler.

There's a famous story that he even made his horse, Incitatus, a senator!
Around this time, construction likely began on the Pont du Gard, a huge aqueduct (a bridge-like structure to carry water) in a Roman province called Gallia Narbonensis (part of modern-day France).
