Because Valentinian III ascended the throne as a child, real power rested with his mother, Galla Placidia, and later with his top generals, particularly Flavius Aetius. Throughout his reign, Valentinian had little control over political or military affairs, with much of the empire’s administration being handled by others.

Key Events During His Rule:

1. The Rise of Flavius Aetius
   One of the most influential figures of Valentinian’s reign was Flavius Aetius, a skilled general who maintained control over much of the empire’s military. Aetius played a key role in stabilizing the empire’s defenses and forming alliances with barbarian groups to counter external threats.

2. The Invasion of Attila the Hun (451 CE)
   One of the defining moments of Valentinian’s rule was the invasion of Gaul by Attila the Hun. In 451 CE, Attila led his forces into Roman territory, threatening to overrun the empire. However, Aetius, in alliance with the Visigoths, defeated Attila at the Battle of the Catalaunian Plains, one of the last great victories of the Western Roman Empire.

3. Murder of Flavius Aetius (454 CE)
   Despite Aetius’ success in defending the empire, Valentinian III became suspicious of his power. In 454 CE, the emperor personally assassinated Aetius during a meeting at the imperial court. This act eliminated Rome’s greatest general at a time when the empire could least afford to lose him. shutdown123
