Thus, this will further prove that the deterioration of the Roman army is one of, if not the main reason that the Western Roman Empire ‘fell’.
To begin, the Emperor Constantine ascended to power in 307 CE upon the death of his father, Constantius, in 306 CE. Under Constantine, there was a shift in the operations and organization of the army from the way in which Diocletian’s army operated. To begin, Constantine was responsible for developing the two tier system of organization within the army. In this system, selected units would make one central field army, and the names of the troops within these armies were known as comitatenses. Although this is not necessarily an addition to the army, as Gallienus’ army in the 260s employed units that served as one field army, and they were deployed to places where crises occurred, it is still significant because Constantine’s systematic implementation of this structure would impact the army for years to come. What is more, it is also an important implementation to note because this was one of Constantine’s new movements in the shift from Diocletian’s army that …show more content…

Constantius soon executes Gallus and appoints one of his relatives, Julian to replace the cruel emperor in the east. Upon taking control of the eastern Empire, Julian begins successful military conquests- one of which was the reconquering of Cologne, an area which had weak fortifications with little troops. This expands on the lack of attention paid to these provinces and the flawed policy of Constantine to pull back troops from these frontiers. What is more, Constantius wanted Julian to gather his troops
