AI overview
I can't write an accurate overview based only on "year" as context, since "450" could refer to many different things—a year in history, a model number, a temperature, or something else entirely. To provide you with accurate, factual information, I would need more specific context about what "450" refers to.

Europe in 450
Year 450 (CDL, CCCCL) was a common year starting on Sunday of the Julian calendar, the 450th Year of the Common Era (CE) and Anno Domini (AD designations, the 450th year of the 1st millennium, the 50th year of the half of 5th century, and the 1st year of the 450s decade. At the time, it was known as the Year of the Consulship of Valentinianus and Avienus (or, less frequently, year 1203 Ab urbe condita). The denomination 450 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.
