This is a list of XII (Byzantine) Eastern Roman Emperors that had been the main target of a plot, had been deposed, assassinated or had been a victim of any kind of misfortune that didn’t end their life naturally. This list does not contain the achievements of the emperors during their reign, just the tragic end that befell on them during their rule.
I. Maurice (582-602)
In 602, Maurice, always dealing with the lack of money, decreed that the army should stay for winter beyond the Danube, which would prove to be a serious mistake. The exhausted troops mutinied against the Emperor. Probably misjudging the situation, Maurice repeatedly ordered his troops to start a new offensive rather than returning to winter quarters. After a while, his troops gained the impression that Maurice no longer mastered the situation, proclaimed Phocas their leader, and demanded that Maurice abdicate and proclaim as successor either his son Theodosius or General Germanus. Both men were accused of treason, but riots broke out in Constantinople, and the emperor left the city with his family for Nicomedia. Theodosius headed east to Persia. Phocas entered Constantinople in November and was crowned Emperor, while his troops captured Maurice and his family. Maurice was murdered on 27 November 602 (some say 23 November). It is said that the deposed emperor was forced to watch his six sons getting executed before he was beheaded himself.
II. Phocas (602-610)

On October 3 610 C.E., his ships appeared under the walls of Constantinople. Here hailed as a liberator, he soon ended Phocas government on October 5, and by the hands of the Patriarch, Heraclius received the crown.

After a penal expedition of 709 C.E. in Ravenna in late 710 C.E. or early 711 C.E. there was an uprising, Justinian sent a similar expedition in Kherson, his former place of exile. Here vengeance was more fierce, and it would cost Justinian II his head. At First the rebellion had affected the population of Kherson, and then it extended to the imperial army and navy.

Leo was attending the matins service when a group of assassins disguised as monks suddenly threw off their robes and drew their weapons. In the dim light they mistook the officiating priest for the Emperor and the confusion allowed Leo to snatch a heavy cross from the altar and defend himself. He called for his guards, but the conspirators had barred the doors and within a few moments a sword stroke had severed his arm, and he fell before the communion-table, where his body was hewed in pieces. His remains were dumped unceremoniously in the snow and the assassins hurried to the dungeons to free Michael II. Unfortunately for them Leo had hidden the key on his body, and since it was too early in the morning to find a blacksmith Michael was hastily crowned as Emperor with the iron clasps still around his legs. Leon’s four sons were castrated, a procedure so brutally carried out that one of them died during the “operation”.

He became the most intimate friend of Michael III and the husband of his mistress Eudokia Ingerinia. With iron energy, not stopping before anything, he aspired to the highest power. Because of this he came into conflict with the Caesar Bardas, but Michael III succumbed to the influence of his favorite and without hesitation sacrificed his uncle. With deception and perjury Basil and Michael III managed to lure Caesar Varda into a trap: in the campaign in Crete, at time of rest, the Caesar sat on the throne next to his nephew’s sister, Basil attacked him from behind his back and killed him with his own hand (21 April 866). The award was the title of Caesar, which the crown ruler Michael III had gifted to him after returning to Constantinople on 26 May 866. Now Basil received from Michael what this man could give him most. The last act of the bloody tragedy is accelerated by Michael III.

Nikephoros was warned that assassins were in the palace, and he demanded the palace be searched but guards left the room of the empress unsearched, and the assassins avoided capture. Later that night when Nikephorus was asleep on the floor before the holy icons, Tzimiskes and the others sneaked into his bed-chamber, alarmed at first to find the bed empty because Nikephoros frequently slept on the floor. Aroused by the noise, Nikephoros rose just as one of the assassins swung his sword in an attempt to decapitate him. It struck him in the face, and he was then dragged to the foot of the bed, his head was cut off and paraded on a spike, while his body was thrown out the window.
