"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.
