Viterbo (Italian: provincia di Viterbo) is a province in the Lazio region of Italy. Its capital is the city of Viterbo.

Flavius Honorius (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, Honorius ruled the western half of the empire while his brother Arcadius ruled the eastern half. 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 (during his childhood) and his father-in-law (after the emperor became an adult).
