4th-century murdered monarchs

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 Aurelius Valerius Maxentius ( 283 – 28 October 312) was a Roman emperor from 306 until his death in 312. Despite ruling in Italy and North Africa, and having the recognition of the Senate in Rome, he was not recognized as a legitimate emperor by his fellow emperors.

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.

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.

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

Alavivus (flourished in 4th century AD) was a Gothic co-king of a group of Thervingi together with Fritigern. Along with the latter he led the migration of the Thervingi from Dacia across the Danube into the Roman Empire in the late 4th century AD. Upon arrival in the Roman Empire, the Goths suffered from widespread famine, with some Gothic parents reportedly being forced to sell their children into slavery in return for rotten dog meat in order to avoid starvation. In 376, Valens' lieutenant Lupicinus invited Alavivus and Fritigern to a banquet to discuss provisions for their people, where Al
