The "SARMATIA DEVICTA" follis struck at the Arles mint in 323 AD under Emperor Constantine I commemorates the Roman victory over the Sarmatians, a group of Iranian peoples who lived to the northeast of the empire. The inscription meaning "Sarmatia Defeated" celebrates a military conquest significant for the security and expansion of Rome's borders. Coins like these were common tools of imperial propaganda, issued to broadcast military successes to subjects and neighboring peoples alike. The use of provincial mints such as Arles ensured these messages reached a broad audience across the Western provinces. The coin’s iconography and text highlight Constantine’s role as a victorious military commander and consolidate loyalty to his reign during a time of complex political transformations within the empire.
