'' of Constans marked: . After Constantine's death, Constans and his two brothers,
Constantine II and
Constantius II were proclaimed
augusti and divided the Roman empire among themselves on 9 September 337. Constans was left with Italy, Africa and Illyricum. In 338, he campaigned against the
Sarmatians. Meanwhile, Constans came into conflict with his eldest brother Constantine II over the latter's presumed authority over Constans' territory. After attempting to issue legislation to Africa in 339, which was part of Constans' realm, Constantine led his army into an invasion of Italy only a year later. However, he was ambushed and killed by Constans' troops, and Constans then took control of his brother's territories. .
Aquileia, 342 AD –
Bode Museum|alt= Constans began his reign in an energetic fashion. From 341 to 342, he led a campaign against the
Franks where, after an initial setback, the military operation concluded with a victory and a favorable peace treaty.
Eutropius wrote that he "had performed many gallant actions in the field, and had made himself feared by the army through the whole course of his life, though without exercising any extraordinary severity," while
Ammianus Marcellinus remarked that
Julian was the only person the Alamanni feared after the death of Constans. In the early months of 343, he visited
Britain, an event celebrated enough for Libanius to dedicate several sections of his panegyric to explaining it. Although the reasons for the visit remain unclear, the ancient writers were primarily interested in Constans' precarious journey to the province, rather than his actions within it. One theory considers it to have involved the northern frontier, based on Ammianus' remark that he had discussed the
Areani in his now-lost coverage of Constans' reign. Additionally, after recording attacks "near the frontiers" in 360, the historian wrote that the Alamanni were too much of a threat for Julian to confront the problem, in contrast to what Constans was able to do. Constans was accused of employing corrupt ministers during his reign, due to his purported personal greed. One example included the
magister officiorum (master of the offices) Flavius Eugenius, who remained in his position throughout most of the 340s. Despite Eugenius being alleged to have misused his power to seize property, the emperor continued to support him, his trust going as far as to honor him with a statue in the
Forum of Trajan in
Rome.

Religion Constans issued an edict banning superstition and pagan sacrifices in 341, his justification being that he was following the precedent set by his father. Only a short while later though, he tried to moderate his stance by legislating against the destruction of temple buildings. Constans' support of
Nicene orthodoxy and the bishop
Athanasius of Alexandria brought him into conflict with his brother Constantius. Although the two emperors called the
Council of Serdica in 343 to settle the conflict, it was a complete failure, and by 345 Constans was outright threatening civil war against his brother. Eventually, Constantius agreed to allow Athanasius to return to his position, as the bishop's replacement had recently died. Constans also used the military to suppress
Donatism in Africa, where the church was split between Donatists and Catholics.
Alleged homosexuality Constans was targeted with gossip over his personal life. Numerous ancient writers suspected him of homosexuality, perhaps because he never married.
Aurelius Victor charged the emperor with "rabid"
pederasty towards young barbarian hostages, and asserted it was a contributing factor to his unpopularity. Modern scholars have generally doubted the veracity of these claims, with some of them pointing to Constans' legislation against homosexuality in 342. ==Death==
