Frigeridus (dux)

Frigeridus was a Roman military commander (dux) who served during the late 4th century AD. His primary known activity involved leading Roman forces against the invading Germanic tribes, specifically the Goths, who crossed the Danube into Roman territory in 376 AD. He is mentioned in the historical accounts of Ammianus Marcellinus, who provides the most detailed information about his campaigns.

Frigeridus' command was centered in the Balkans, the region most immediately impacted by the Gothic migration. Initially, he attempted to contain the Goths and prevent them from spreading throughout Thrace. He engaged in several skirmishes and battles, often with mixed results. While he achieved some successes, he was ultimately unable to prevent the Goths from causing widespread disruption and devastation.

Sources indicate that Frigeridus faced numerous challenges, including a lack of sufficient troops, logistical difficulties, and the internal political intrigues that plagued the late Roman Empire. He also contended with the growing disaffection of some Roman soldiers and the widespread corruption within the administration.

Later in the Gothic War, Frigeridus appears to have been replaced or transferred, although the precise circumstances are unclear. He disappears from the historical record after the early stages of the conflict, and his ultimate fate is unknown. While not one of the most prominent figures of the Gothic War, Frigeridus represents a typical Roman commander of the era tasked with defending the Empire's frontiers against increasingly formidable barbarian incursions.
