Final answer:
Domitian's reign came to a violent close when he was assassinated in 96 CE by a group of conspirators.
Step-by-step explanation:
Domitian's reign ended violently when he was assassinated in 96 CE by a group of conspirators in the palace. Domitian, like Nero, was a ruler marked by insecurity and suspicion, often using the Praetorian Guard to arrest and execute his critics in the Senate. His wife Domitia worked with members of the Senate to arrange for his assassination. This event marked the end of Domitian's rule and the beginning of a transition period in Roman history.
