Coins from Late Roman Empire
The Late Roman Empire category covers the final years of the Roman Empire as a united realm; from the ascencion of Valentinian I on 364 AD to the death of Theodosius I in 395 AD, the last emperor to rule both the western and eastern parts of the empire.

This is not to say that the Empire was united during this period of history; the brothers Valentinian I and Valens ruled separate halfs of the empire in a fashion superficially similar to the brothers Honorius & Arcadius, the sons of Theodosius I. Still, Valentinian dynasty and Thodosius I represent the last competent emperors who even attempted to pursue policies which benefitted both halfs of the Empire and after their deaths the two halves would drift slowly but surely apart.

Militarily, this period was characterized by the invasions and revolts of the Goth with the disastrous Battle of Adrianople at the center of the stage; Valens was killed alongside two thirds of the Roman army. The goths would have free access to plundering the countryside for years, and much of the Roman army would henceforth consist of Germanic mercenaries. This would lead to further problems down the road, especially in the West.

Flavius Julius Valens Augustus was Eastern Roman Emperor from 364 to 378.

He was given the eastern half of the empire by his brother Valentinian I after the latter's accession to the throne.

He was a careful administrator, but very suspicious of plots and without any military merit whatsoever.

In 378, Valens fought the combined forces of the Visigoths at Adrianop...
Procopius was a member of the Constantinian dynasty and a usurper against Valentinian I and Valens in 365-366 AD.

According to Zosimus, Julian had given Procopius an imperial robe. When Jovian was acclaimed Emperor, Procopius gave him the robe and asked to be allowed to retire to private life. Jovian accepted.

Flavius Valentinianus Augustus was Roman Emperor from AD 375 to 392.

Valentinian himself seems to have exercised no real authority, and was a figurehead for various powerful interests: his mother, his co-emperors, and powerful generals.

He was thoroughly dominated by the Frankish general Arbogast. When Valentinian formally dismissed Arbogast, the latter ignored the order, pub...
Flavius Theodosius Augustus, also known as Theodosius the Great, was Roman Emperor from AD 379 to AD 395.

She died early in 386, aged 30.
Flavius Magnus Maximus Augustus was Western Roman Emperor from 383 to 388.

In 387, Maximus' ambitions led hi...
Flavius Victor Augustus was the son of Magnus Maximus. He was proclaimed an Augustus by his father and ruled nominally from 384 to his death in 388.
