AI overview
I don't have enough context to write an accurate overview. You've indicated the context is "year," but 73 could refer to many different years (1973, 2073, or 73 AD, for example), each with different historical significance. Could you clarify which year or event associated with 73 you'd like me to describe?

AD 73 (LXXIII) was a common year starting on Friday of the Julian calendar. At the time, it was known as the Year of the Consulship of Domitian and Messalinus (or, less frequently, year 826 Ab urbe condita). The denomination AD 73 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.
