Aurelian (; ; 9 September ) was a Roman emperor from 270 to 275 during the Crisis of the Third Century. During his reign, 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. For his success in restoring the Empire's territorial integrity, Aurelian was honored with the title ("Restorer of the World").

Publius Licinius Egnatius Gallienus (, ; – September 268) was Roman emperor with his father Valerian from 253 to 260 and alone from 260 to 268. He ruled during the Crisis of the Third Century that nearly caused the collapse of the empire. He won numerous military victories against usurpers and Germanic tribes, but was unable to prevent the secession of important provinces. His 15-year reign was the longest in half a century.

Marcus Aemilius Aemilianus ( – September 253), also known as Aemilian, was Roman emperor for two months in 253.

Marcus Aurelius Claudius Quintillus (died 270) was a short-lived Roman emperor. He took power after the death of his brother, Emperor Claudius Gothicus, in 270. After reigning for a few weeks Quintillus was overthrown by Aurelian, who had been proclaimed rival emperor by the legions he commanded. The ancient sources variously report him to have killed himself, to have fallen in battle against Aurelian, or to have been murdered by his own soldiers.
