Why was a Roman Emperor erased from history by his own family?

In short: Constantine II ruled the Roman Empire for three years, yet he was eventually branded a public enemy and scrubbed from official records. His short reign was defined by a desperate, fatal struggle to assert seniority over his brothers, culminating in a failed invasion that cost him his life.

Born in 316 to Emperor Constantine I and Fausta, Constantine II was groomed for power from birth. Proclaimed caesar in 317, he spent his youth securing military credentials, including victories over the Goths and Alamanni. By the time his father died in 337, Constantine II was poised to lead, but he faced a complex political landscape. His father had intended for his sons to share power with cousins Dalmatius and Hannibalianus, an arrangement the brothers rejected. Shortly after their father's death, a brutal purge of these relatives occurred, orchestrated by Constantine II's brother, Constantius II.

Constantine II believed his age granted him authority over his younger siblings, particularly Constans, who controlled Italy and Africa. This conviction led to persistent friction. He attempted to exert influence beyond his own territories in Gaul, Hispania, and Britain, even issuing legislative edicts in Constans's domain. His efforts to assert seniority were not limited to politics; he also engaged in religious maneuvering, such as ordering the return of the exiled bishop Athanasius to Alexandria, potentially to undermine his brother Constantius II.

The tension reached a breaking point in April 340, when Constantine II launched an invasion of Italy. The campaign ended in disaster near Aquileia, where he was killed in an ambush. Following his death, his brother Constans moved to erase his legacy. Constantine II was subjected to damnatio memoriae, a formal condemnation that saw his laws repealed and his name struck from public memory. Later panegyrics by writers like Libanius omitted him entirely, treating his brief reign as if it had never occurred, leaving him a ghost in the annals of the Roman Empire.
