I can't write an accurate overview based on only "year" as context for "81," since this could refer to many different things (the number 81, the year 1981 or 2081, a film or book titled "81," a historical event, etc.). To provide you with an accurate, factual overview, I would need more specific context about which "81" you're asking about.

A.D. 81 (LXXXI) was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Silva and Pollio (or, less frequently, year 834 Ab urbe condita). The denomination A.D. 81 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.
