Marcus Claudius Tacitus was Roman emperor from 275 to 276. During his short reign he campaigned against the Goths and the Heruli, for which he received the title Gothicus Maximus.
The 280's decade ran from January 1, 280, to December 31, 289.
Aurelian was a Roman emperor, who reigned during the Crisis of the Third Century, from 270 to 275. As emperor, he won an unprecedented series of military victories which reunited the Roman Empire after it had nearly disintegrated under the pressure of barbarian invasions and internal revolts. Born in modest circumstances, near the Danube River, he entered the Roman army in 235 and climbed up the ranks. He went on to lead the cavalry of the emperor Gallienus, until Gallienus' assassination in 268. Following that, Claudius Gothicus became emperor until his own death in 270. Claudius' brother Quintillus ruled the empire for three months, before Aurelian became emperor.

Flavius Valerius Constantius "Chlorus", also called Constantius I, was Roman emperor from 305 to 306. He was one of the four original members of the Tetrarchy established by Diocletian, first serving as caesar from 293 to 305 and then ruling as augustus until his death. Constantius was also father of Constantine the Great, the first Christian emperor of Rome. The nickname Chlorus was first popularized by Byzantine-era historians and not used during the emperor's lifetime.

Marcus Aurelius Probus was Roman emperor from 276 to 282. Probus was an active and successful general as well as a conscientious administrator, and in his reign of six years he secured prosperity for the inner provinces while withstanding repeated invasions of barbarian tribes on almost every sector of the frontier.
Marcus Aurelius Carinus was Roman emperor from 283 to 285. The elder son of emperor Carus, he was first appointed Caesar and in the beginning of 283, with the title of Augustus, he was appointed co-emperor of the western portion of the empire by his father. Official accounts of his character and career, which portray him as debauched and incapable, have been filtered through the propaganda of his successful opponent, Diocletian.
Marcus Aurelius Carus was Roman emperor from 282 to 283. During his short reign, Carus fought the Germanic tribes and Sarmatians along the Danube frontier with success.
Gordian I was Roman emperor for 22 days with his son Gordian II in 238, the Year of the Six Emperors. Caught up in a rebellion against the Emperor Maximinus Thrax, he was defeated by forces loyal to Maximinus, and he committed suicide after the death of his son.
Gordian II was Roman emperor with his father Gordian I in 238 AD, the Year of the Six Emperors. Seeking to overthrow Maximinus Thrax, he died in battle outside Carthage. Since he died before his father, Gordian II had the shortest reign of any Roman emperor, at 22 days.

The Historia Augusta is a late Roman collection of biographies, written in Latin, of the Roman emperors, their junior colleagues, designated heirs and usurpers from 117 to 284. Supposedly modeled on the similar work of Suetonius, The Twelve Caesars, it presents itself as a compilation of works by six different authors, written during the reigns of Diocletian and Constantine I and addressed to those emperors or other important personages in Ancient Rome. The collection, as extant, comprises thirty biographies, most of which contain the life of a single emperor, but some include a group of two or more, grouped together merely because these emperors were either similar or contemporaneous.
SextusJulius Saturninus was a Roman usurper against Emperor Probus.
Bonosus was a late 3rd-century Roman usurper. He was born in Hispania to a British father and Gallic mother. His father—a rhetorician and "teacher of letters"—died when Bonosus was still young but the boy's mother gave him a decent education. He had a distinguished military career with an excellent service record. He rose successively through the ranks and tribuneships but, while he was stationed in charge of the Rhenish fleet c. 280, the Germans managed to set it on fire. Fearful of the consequences, he proclaimed himself Roman emperor at Colonia Agrippina (Cologne) jointly with Proculus. After a protracted struggle, he was defeated by Marcus Aurelius Probus and hanged himself rather than face capture.
Cyriades was a Roman rebel who betrayed the city of Antioch to Shapur I sometime during the 250s. His chief claim to fame is that he is enumerated as one of the Thirty Tyrants who supposedly tried to overthrow the emperor Gallienus.
The Gallienus usurpers were the usurpers who claimed imperial power during the reign of Gallienus. The existence of usurpers during the Crisis of the Third Century was very common, and the high number of usurpers fought by Gallienus is due to his long rule; fifteen years was a long reign by the standards of the 3rd century Roman Empire.
Maeonius, or Maconius, was a fictional usurper who, according to the Historia Augusta, briefly ruled over Palmyra. He is included in the list of the Thirty Tyrants.
