During the Crisis of the Third Century, 26 Roman emperors were murdered over a period of 50 years.

"26 emperors were murdered in a period of 50 years." (said at 0:00:13)

During the Crisis of the Third Century (traditionally dated 235–284 CE, a span of roughly 50 years between the death of Severus Alexander and the accession of Diocletian), approximately 26 men are recognized by traditional Roman historical convention as legitimate or Senate-recognized emperors (the "barracks emperors"). While the period was characterized by extreme political instability and most rulers met violent ends (predominantly assassination, troop mutinies, or death in battle), not all 26 were murdered; notable exceptions include Claudius Gothicus and Hostilian, who died of plague, and Valerian, who died in Persian captivity. If usurpers and regional claimants (such as those in the Gallic and Palmyrene empires) are included, the total number of individuals claiming imperial authority during these 50 years exceeds 50.

During the Crisis of the Third Century, 26 emperors were murdered over a 50-year period.

"Let's talk about the crisis of the 3rd century where 26 emperors were murdered in a period of 50 years." (said at 0:57:15)

During the Crisis of the Third Century (traditionally dated from the assassination of Severus Alexander in 235 CE to the accession of Diocletian in 284 CE, a period of roughly 50 years), approximately 26 distinct individuals were recognized as legitimate Roman emperors by the Senate, alongside dozens of usurpers and regional claimants. While political violence was exceptionally rampant and the majority of these rulers were assassinated, mutinied against, or killed in civil conflict, not all 26 were murdered. For instance, Claudius Gothicus and Hostilian died of infectious disease (the Plague of Cyprian), Decius was killed in battle against the Goths, and Valerian died in Persian captivity. Thus, 26 represents the approximate total number of recognized emperors during the 50-year crisis, rather than the count of murdered rulers.
