During the decline of the Roman Empire, the Roman emperors usually died by being killed in battle or being killed

by assassination. The instability of the empire during this time period led to frequent power struggles among factions vying for control, which often resulted in violence and bloodshed. Emperors such as Julius Nepos, Romulus Augustulus, and Julius Caesar were all killed either in battle or by assassination as the empire crumbled around them. These violent deaths of emperors only added to the chaos and turmoil of the declining Roman Empire.
