Emperor Domitian, despite his initially peaceful rule, became very suspicious over time. He was almost always accompanied by a guard. He covered the walls of his palace with shiny stone (the so-called fengit) so that he could see what was happening behind his back thanks to the gloss.
Domitian reportedly even said: “unfortunate is the fate of the principals, because they will not believe reports of the plot until they are murdered.” As it turned out, his suspicions were correct. Senators were not favourable to him, and neither were many of his associates. Finally, his wife, Domitia Longina, entered into a plot with his trusted freedmen and two Praetorian prefects.
The emperor was stabbed to death in 96 CE. Thus ended her reign of the Flavian dynasty.
