256
year

Year 256 (CCLVI) was a leap year starting on Tuesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Claudius and Glabrio (or, less frequently, year 1009 Ab urbe condita). The denomination 256 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.

Why this record matters
A short description can identify a subject without explaining its stakes. For “256”, the useful work is to connect “year” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 25, 2026. The linked authority identifier is Q31712. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1009.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
