Diocletian was a Roman emperor from 284 to 305. Born to a family of low status in Dalmatia, Diocletian rose through the ranks of the military to become a cavalry commander of the Emperor Carus's army. After the deaths of Carus and his son Numerian on campaign in Persia, Diocletian was proclaimed emperor. The title was also claimed by Carus's surviving son, Carinus, but Diocletian defeated him in the Battle of the Margus.

He was a junior-ranking emperor, or Caesar, from 293 to 305, and senior emperor, Augustus, from 305 to 306. Constantius was also the father of Constantine the Great, the first Christian emperor of Rome. The nickname Chlorus was first popularized by Byzantine-era historians and was not used during the emperor's lifetime.
Numerian was Roman emperor from 283 to 284 with his older brother Carinus. They were sons of Carus, a general raised to the office of praetorian prefect under Emperor Probus in 282.
Maximian, nicknamed Herculius, was Roman emperor from 286 to 305. He was Caesar from 285 to 286, then Augustus from 286 to 305. He shared the latter title with his co-emperor and superior, Diocletian, whose political brain complemented Maximian's military brawn. Maximian established his residence at Trier but spent most of his time on campaign. In late 285, he suppressed rebels in Gaul known as the Bagaudae. From 285 to 288, he fought against Germanic tribes along the Rhine frontier. Together with Diocletian, he launched a scorched earth campaign deep into Alamannic territory in 288, temporarily relieving the Rhine provinces from the threat of Germanic invasion.
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 co-emperor of the western portion of the empire by his father.

He held power for seven years, fashioning the name "Emperor of the North" for himself, before being assassinated by his finance minister Allectus.
Marcus Aurelius Sabinus Julianus was a Roman usurper against Emperor Carinus or Maximian. It is possible that up to four usurpers with a similar name rebelled in a timeframe of a decade, but at least one of them is known by numismatic evidence.
Marcus Aurelius was a name used by men from the Roman Empire and afterwards. The earliest so called was the emperor Marcus Aurelius.
