Executed Roman emperors

Aulus Vitellius ( ; 24 September 1520 December 69) was Roman emperor, ruling for eight months from 19 April to 20 December AD 69. Vitellius became emperor following the quick succession of the previous emperors Galba and Otho, in a year of civil war known as the Year of the Four Emperors. Vitellius added the honorific title Germanicus to his name instead of Caesar upon his accession. Like his predecessor, Otho, Vitellius attempted to rally public support to his cause by honoring and imitating Nero who remained popular in the empire.

Marcus Opellius Macrinus (; – June 218) was a Roman emperor who reigned from April 217 to June 218, jointly with his young son Diadumenianus. Born in Caesarea (now called Cherchell, in modern Algeria), in the Roman province of Mauretania Caesariensis to an equestrian family of Berber origins, he became the first emperor who did not hail from the senatorial class and also the first emperor who never visited Rome during his reign. Before becoming emperor, Macrinus served under Emperor Caracalla as a praetorian prefect and dealt with Rome's civil affairs. He later conspired against Caracalla and

Valerius Licinianus Licinius (; Greek: Λικίνιος; c. 265 – 325) was Roman emperor from 308 to 324. For most of his reign, he was the colleague and rival of Constantine I, with whom he co-authored the Edict of Milan that granted official toleration to Christians in the Roman Empire. He was finally defeated at the Battle of Chrysopolis (AD 324), and was later executed on the orders of Constantine.

Marcus Clodius Pupienus Maximus ( 164–238) was Roman emperor with Balbinus for 99 days in 238, during the Year of the Six Emperors. The sources for this period are scant, and thus knowledge of the emperor is limited. In most contemporary texts he is referred to by his cognomen "Maximus" rather than by his second nomen (family name) Pupienus ().

Decimus Caelius Calvinus Balbinus (July/August 238 AD) was Roman emperor with Pupienus for three months in 238, the Year of the Six Emperors.

Diadumenian ( ; ; 14September 208 – June 218) was the son of the Roman emperor Macrinus and served as his co-ruler for a brief time in 218. His mother, Macrinus' wife, is called Nonia Celsa in the unreliable , though this name may have been fictional. Diadumenian became in May 217, shortly after his father's accession to the imperial throne. Elagabalus, a relative of the recently deceased Caracalla, revolted in May of the following year, and Diadumenian was elevated to co-emperor. After Macrinus was defeated in the Battle of Antioch on 8 June 218, Diadumenian was sent to the court of Artabanus

Gratian (; ; 18 April 359 – 25 August 383) was emperor of the Western Roman Empire from 367 to 383. The eldest son of Valentinian I, Gratian was raised to the rank of Augustus as a child and inherited the West after his father's death in 375. He nominally shared the government with his infant half-brother Valentinian II, who was also acclaimed emperor in Pannonia on Valentinian's death. The East was ruled by his uncle Valens, who was later succeeded by Theodosius I.

Majorian (; 7 August 461) was Western Roman emperor from 457 to 461. A prominent commander in the Western military, Majorian deposed Avitus in 457 with the aid of his ally Ricimer at the Battle of Placentia. Possessing little more than Italy and Dalmatia, as well as some territory in Hispania and northern Gaul, Majorian campaigned vigorously for three years against the Empire's enemies. In 461, he was murdered at Dertona in a conspiracy, and his successors until the fall of the Empire in 476 were puppets either of barbarian generals or the Eastern Roman court.

Phocas (; ; 5475 October 610) was Eastern Roman emperor from 602 to 610. Initially a middle-ranking officer in the Roman army, Phocas rose to prominence as a spokesman for dissatisfied soldiers in their disputes with the court of the Emperor Maurice. When the army rebelled in 602, Phocas emerged as the leader of the mutiny. The revolt led to the overthrow and execution of Maurice in November 602.

Flavius Julius Constans ( 323 – 350), also called Constans I, was Roman emperor from 337 to 350. He held the imperial rank of caesar from 333, and was the youngest son of Constantine the Great.

Eparchius Avitus (died 456/7) was Roman emperor of the Western Empire from July 455 to October 456. He was a senator of Gallic extraction and a high-ranking officer both in the civil and military administration, as well as Bishop of Piacenza.

Basiliscus (; died 476/477) was Eastern Roman emperor from 9 January 475 to August 476. He became in 464, under his brother-in-law, Emperor Leo I (457–474). Basiliscus commanded the army for an invasion of the Vandal Kingdom in 468, which was defeated at the Battle of Cape Bon. There were accusations at the time that Basiliscus was bribed by Aspar, the ; many historians dismiss this, instead concluding that Basiliscus was either incompetent or foolish for accepting Vandal King Gaiseric's offer of a truce, which the latter used to construct fireships. Basiliscus's defeat cost the Eastern Empire

Procopius Anthemius (; died 11 July 472) was the Western Roman emperor from 467 to 472. Born in the Eastern Roman Empire, Anthemius quickly worked his way up the ranks. He married into the Theodosian dynasty through Marcia Euphemia, daughter of Eastern emperor Marcian. He soon received a significant number of promotions to various posts, and was presumed to be Marcian's planned successor. However, Marcian's sudden death in 457, together with that of Western emperor Avitus, left the imperial succession in the hands of Aspar. He instead appointed Leo, a low-ranking officer, to the Eastern throne

Leontius (; died 15 February 706) was Byzantine emperor under the regnal name Leo from 695 to 698. Little is known of his early life, other than that he was born in Isauria in Asia Minor. He was given the title of patrikios, and made strategos of the Anatolic Theme under Emperor Constantine IV. He led forces against the Umayyads during the early years of Justinian II's reign, securing victory and forcing the Umayyad caliph, Abd al-Malik ibn Marwan, to sue for peace.

Eugenius (died 6 September 394) was a Western Roman emperor from 392 to 394, unrecognized by the Eastern Roman emperor Theodosius I. While Christian himself, Eugenius capitalized on the discontent in the West caused by Theodosius' religious policies targeting pagans. He renovated the pagan Temple of Venus and Roma and restored the Altar of Victory after continued petitions from the Roman Senate. Eugenius replaced Theodosius' administrators with men loyal to him. This included pagans, reviving the pagan cause. His army fought the army of Theodosius at the Battle of the Frigidus, where he was ca
