Year 525 (DXXV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Probus and Philoxenus (or, less frequently, year 1278 Ab urbe condita). The denomination 525 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. In this year, the monk Dionysius Exiguus proposed a calendar starting with the birth of Jesus (the AD system), so this was the first time the year was designated AD. However, the system was not used in general until the reign of Charlemagne in the 9th century.

Byzantine Empire[edit]





  • The Daisan river, tributary of the Euphrates, floods Edessa, and within a couple of hours fills the entire city, except for the highest parts. Eventually the pent-up waters break through the city walls. The Shroud of Turin is allegedly discovered during the rebuilding of the city (see Image of Edessa).
