Was the unification of the empire lasting under Aurelian?

Lucius Aurelian was the emperor of the Roman Empire from 270 to 275. At this time, it was engulfed in uprisings and disintegrated into the Roman itself, separatists from the Palmyra Empire and the Gali Empire. During his reign, the Illyrian emperor suppressed separatist sentiments and reunited the empire in 274. He also repulsed the multiple invasions of the Germanic tribes into the state and carried out a religious reform, introducing the worship of the eastern cult of the Invincible Sun.
