The period from the mid fourth the the mid fifth centuries was one characterized by great instability. The empire had outgrown itself, its size making it difficult for a single emperor to manage. More ofter, power was shared by two or more Augusti, each one’s existence strengthening the position of his colleague. As such, an emperor would likely mint coinage both in his own name and in that of his peer. Of course, relations between the two colleagues would often deteriorate, and the empire saw considerable civil conflict.

On the borders of the empire various barbaric tribes were challenging borders, ravaging communities, and ultimately were seen as endangering civilization itself. Internally, usurpers were constantly appearing. These usurping emperors generally had one of two ambitions. In some instances, their goal would be to kill one of the existing Augusti and to take up the rule of their territory. Constans lost his life to one such plot. At the time his court was staying at Autun, where he was hunting. One of the court, a man by the name of Marcellinus, orchestrated the plot to put Magnentius in power. The former gave a party on the birthday of his son. During the course of the event, Magnentius suddenly entered, dressed in imperial robes, and was proclaimed emperor by the guests, including several senior officers in Constans' army. The people of Autun and the army followed suit, and Constans fled. He was soon after caught and executed. (Kent 1981, 9)

Alternatively, occassionally a usurper would attempt to simply take control of a piece of territory, and hope to be acknowledged by the existing Augustus as a colleague. Procopius was one such usurper. 

The results of these threats were that the emperors of this period were highly insecure. Threatened by foreign invasion, conspiracy, and insurrection, popular support was both highly important and remarkably capricious. The period Augusti generally used coinage as best they could to validate their own legitimacy, and to communicate images of military potency. This can be seen reflected on either side of the coin. On the obverse, the portrait busts become uniform and idealized, reflecting not only the shift away from classical representational portraiture, as well as the popular sentiment that imperial portraiture ought to emphasize imperial majesty rather than revealing the rulers physical imperfections (Gierson and Mays, 74). It seems appropriate that such sentiments would prevail during a time in which the popularity and well-being of the emperor were in near-constant peril. The coin reverses can be seen to reflect the same conditions. Some of these are aimed at implying unity among the various emperors and across the empire. Others clearly bespeak the ruler's military potency. Still others tend to associate the Augustus with the God, emphasizing that he has been appointed by the divine. Examples of each can be seen in the loan collection.
