This paper analyzes Carthage’s strategic approach during the First Punic War, contrasting its continuity-based tactics with Rome’s adaptable strategies. Carthage relied on alliances, naval dominance, and mercenary forces to counter Rome’s advances in Sicily. However, Rome’s effective use of "fides" as a mean of soft power destabilized Carthaginian influence, aligning key Sicilian cities with Roman interests. While Carthage demonstrated resilience through defensive and counter-offensive operations, its inability to adapt strategically marked a turning point, solidifying Rome’s ascent as a Mediterranean power.
