AI overview
I don't have enough context to write an accurate overview of "325." While you've indicated this relates to a year, "325" could refer to many different historical events or topics that occurred in that year (such as events in 325 AD, or other contexts entirely), and I cannot determine which one you're asking about without additional information. Could you provide more context about what aspect of 325 you'd like me to explain?

Constantine the Great summons the Christian Church to Nicaea (mosaic in Hagia Sophia, Istanbul)
Year 325 (CCCXXV) was a common year starting on Friday of the Julian calendar. At the time, it was known as the Year of the Consulship of Proculus and Paulinus (or, less frequently, year 1078 Ab urbe condita). The denomination 325 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.
