VALENTINIAN II (Flavius Valentinianus)
- Valentinian II was the younger son of Valentinian I by his second wife, Justina.
- Following his father's death in 375, he was proclaimed co-emperor in the west with his half-brother, Gratian. As he was only four years of age, he was initially was under the protection of Gratian.
- In 383 Magnus Maximus, Gratian's commander in Britain, rebelled. Deserted by his troops, Gratian was killed at Lugdunum (Lyon). Thus at the age of twelve, Valentinian became the sole legitimate emperor in the west. He moved his court to Milan, where his mother managed his affairs.
- When Magnus Maximus invaded Italy in 387 Valentinian fled. Theododius, the eastern emperor came to his aid and defeated the usurper, re-establishing Valentinian in the West.
- Valentinian was dominated by his general Arbogast, and was either killed by him or committed suicide (May, 392).
