Year 273 (CCLXXIII) 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 Tacitus and Placidianus (or, less frequently, year 1026 Ab urbe condita). The denomination 273 for this year has been used since the early medieval period, when the Anno Dominicalendar era became the prevalent method in Europe for naming years.[1] The year also saw most lost territories to rebellion returned to the Roman Empire by Emperor Aurelian.[2]

In bitter street-fighting, Aurelian crushes a rebellion in Alexandria by Firmus, a sympathizer of Palmyra. Firmus is strangled to death.
