Historical Context and Fidelity 300: Rise of an Empire draws loosely on the same historical events that inspired Frank Miller’s graphic narratives: the Greco-Persian Wars, notably the Battles of Marathon, Thermopylae, Salamis, and Plataea (circa 490–479 BCE). The film foregrounds the naval Battle of Salamis (480 BCE), where Athenian-led sea forces played a decisive role. However, the film operates primarily in the register of myth rather than historiography. Key figures are conflated or dramatized for narrative effect: Themistocles is depicted as a tactical naval commander whose actions align with Miller’s heroic archetype more than the complex Athenian politician recorded by Herodotus and later historians; Artemisia—presented as a vengeful, calculating naval commander and Xerxes’ principal advisor—draws from Herodotus’s account but is exaggerated into a near-archvillainess with sexualized villainy and melodramatic motivations. Xerxes’ depiction as a god-king under supernatural thrall also departs significantly from Persian royal ideology as reconstructed by modern historians, reducing geopolitical complexity to personalized tyranny.
