Honorius [1] 9 September 384 – 15 August 423) was Roman emperor from 393 to 423. He was the younger son of emperor Theodosius I and his first wife Aelia Flaccilla. After the death of Theodosius in 395, Honorius, under the regency of Stilicho, ruled the western half of the empire while his brother Arcadius ruled the eastern half. His reign over the Western Roman Empire was precarious and chaotic. In 410, Rome was sacked for the first time since the Battle of the Allia almost 800 years prior
Honorius died of edema on 15 August 423, leaving no heir. In the subsequent interregnum Joannes was nominated Emperor. The following year, however, the Eastern Emperor Theodosius II installed his cousin Valentinian III, son of Galla Placidia and Constantius III, as Emperor.
