Year 190 (CXC) was a common year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Sura (or, less frequently, year 943 Ab urbe condita). The denomination 190 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.
