Flavius Honorius was Roman emperor from 393 to 423. He was the younger son of emperor Theodosius I and his first wife Aelia Flaccilla, and brother of Arcadius, who ruled the eastern half of the empire from 395, when their father died, until his death in 408. In 410, during Honorius's reign over the western Roman Empire, Rome was sacked for the first time in almost 800 years.
Even by the standards of the Western Empire, Honorius's reign was precarious and chaotic. His early reign was supported by his principal general, Stilicho, who was successively Honorius's guardian and his father-in-law.
