Assassination attempt (Commodus)

The first crisis of the reign came in 182 when Lucilla engineered a conspiracy against her brother. Her motive is alleged to have been the envy of Empress Crispina. Her husband, Pompeianus, was not involved, but two men alleged to have been her lovers, Marcus Ummidius Quadratus Annianus (the consul of 167, who was also her first cousin) and Appius Claudius Quintianus, attempted to murder Commodus as he entered a theater. They bungled the job and were seized by the emperor's bodyguard.
