Year 193 (CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 Ab urbe condita). The denomination 193 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.
June 1 – Septimius Severus enters the capital, and has Julianus put to death. He replaces the Praetorian Guard with a 15,000-man force from the Danubian legions, and gains control of the Roman Empire, beginning the Severan dynasty.
In Britain, Clodius Albinus allies with Septimius Severus, and accepts the title of Caesar. British tribes take advantage of the disorder in the Empire, and damage Hadrian's Wall. Extensive repairs to the defence work is carried out by the legionaries.
Counterfeiting workshops begin to appear throughout the Roman Empire.
