Valentinian II

Valentinian II (Latin: Flavius Valentinianus Augustus; 371 – 15 May 392), was Roman Emperor from AD 375 to 392.

Early life and accession (371–375)

Flavius Valentinianus was born to Emperor Valentinian I and his second wife, Justina. He was the half-brother of Valentinian’s other son, Gratian, who had shared the imperial title with his father since 367. He had three sisters Galla, Grata and Justa. The elder Valentinian died on campaign in Pannonia in 375. Neither Gratian (then in Trier) nor his uncle Valens (emperor for the East) were consulted by the army commanders on the scene. Instead of merely acknowledging Gratian as his father’s successor, Valentinian I’s generals acclaimed the four-year-old Valentinian augustus on 22 November 375. The army, and its Frankish general Merobaudes, may have been uneasy about Gratian's lack of military ability, and so raised a boy who would not immediately aspire to military command.

Reign from Milan (375–387)

Gratian, forced to accommodate the generals who supported his half-brother, governed the trans-alpine provinces (including Gaul, Hispania, and Britain), while Italy, part of Illyricum, and Africa were under the rule of Valentinian. In 378, their uncle, the Emperor Valens, was killed in battle with the Goths at Adrianople, and Gratian invited the general Theodosius to be emperor in the East. As a child, Valentinian II was under the influence of his Arian mother, the Empress Justina, and the imperial court at Milan, an influence contested by the Catholic bishop of Milan, Ambrose.

List of Roman emperors

Roman Emperors and Empresses were rulers of the Roman Empire, wielding power over its citizens and military. The empire was developed as the Roman Republic invaded and occupied most of Europe and portions of northern Africa and western Asia. Under the republic, regions of the empire were ruled by provincial governors answerable to and authorised by the "Senate and People of Rome". Rome and its senate were ruled by a variety of magistrates – of whom the consuls were the most powerful. The republic ended, and the emperors were created, when these magistrates became legally and practically subservient to one citizen with power over all other magistrates. Augustus, the first emperor, was careful to maintain the facade of republican rule, taking no specific title for his position and calling the concentration of magisterial power Princeps Senatus (the first man of the senate). This style of government lasted for 300 years, and is thus called the Principate era. The modern word 'emperor' derives from the title imperator, which was granted by an army to a successful general; during the initial phase of the empire, it still had to be earned by the 'Princeps'. The term emperor is a modern construction, used when describing rulers of the Roman Empire because it emphasises the strong links between the ruler and the army (on whose support the ruler's power depended), and does not discriminate between the personal styles of rule and titles in different phases of the Empire.

Valentinian I

Valentinian I (Latin: Flavius Valentinianus Augustus; 321 – 17 November 375), also known as Valentinian the Great, was Roman emperor from 364 to 375. Upon becoming emperor he made his brother Valens his co-emperor, giving him rule of the eastern provinces while Valentinian retained the west.

During his reign, Valentinian fought successfully against the Alamanni, Quadi, and Sarmatians. Most notable was his victory over the Alamanni in 367 at the Battle of Solicinium. His brilliant general Count Theodosius defeated a revolt in Africa and the Great Conspiracy, a coordinated assault on Roman Britain by Picts, Scots, and Saxons. Valentinian was also the last emperor to conduct campaigns across both the Rhine and Danube rivers. Valentinian rebuilt and improved the fortifications along the frontiers, even building fortresses in enemy territory.

Due to the successful nature of his reign and the rapid decline of the empire after his death, he is often considered to be the "last great western emperor". He founded the Valentinian Dynasty, with his sons Gratian and Valentinian II succeeding him in the western half of the empire.
