Didius Julianus
Marcus Silius Messala (born ca. AD 160, fl.193) was a Roman senator and suffect consul towards the end of the 2nd century. In 193, Messala was the suffect consul from May until June. He was in command of the location where the murder of Pertinax took place. Septimius Severus accused Messala of murdering Pertinax and using his influence to convene and order the Senate to install the Senator Didius Julianus as Emperor. Septimius Severus called the death of Didius Julianus divine providence and ordered the execution of Messala.
