Heraclianus was a provincial governor and a usurper of the Western Roman Empire (412–413) opposed to Emperor Honorius, who had originally brought him to power. Heraclianus helped put down a rebellion by Priscus Attalus. However, he decided to stage his own rebellion and during his invasion of the Italian peninsula, was either defeated in battle or captured and executed.

Honorius 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 notably precarious and chaotic. In 410, Rome was sacked for the first time in almost 800 years.
