===Reign===
During this time period, generals played a critical role in ensuring the continued reign of Roman Emperors, especially Western Roman Emperors.{{sfn|Lee|2013|p=82}} Constantius's position of ''magister militum'' and his skill as a commander allowed him to gain huge influence over the Western Roman Empire, comparable to the earlier [[Stilicho]].{{sfn|Adkins|Adkins|2014|p=36}} For this reason, Honorius bestowed many honors upon Constantius,{{sfn|Lee|2013|p=82}} such as appointing him consul three times: in 414, alongside [[Constans (consul 414)|Constans]]; in 417, alongside Honorius;{{Sfn|Grant|2015|p=60}}{{sfn|Cooley|2012|p=482}} and in 420, alongside [[Theodosius II]].{{Sfn|Grant|2015|p=60}}{{sfn|Cooley|2012|p=483}} In order to further ensure Constantius's loyalty, Honorius arranged the betrothal of his sister, [[Galla Placidia]], to Constantius in 417.{{Sfn|Grant|2015|p=60}} Later, on 8 February 421, Honorius made Constantius co-Western Emperor under himself. However, his cousin Theodosius II, emperor of the Eastern Empire, did not recognize him as such. Reportedly, Constantius was angry about this and considered starting a campaign against Theodosius.
