The official account of Darius's rise to power involves him deposing a magical imposter who looked exactly like the murdered royal heir, Bardia. Historians believe this is a highly improbable cover story for what was actually a violent coup where Darius himself murdered the legitimate heir to seize the throne.

Darius portrayed himself as an agent of cosmic truth and order ('Arta'). He branded enemies not just as political opponents but as agents of a universal lie ('Drauga'), turning rebellion into a moral and religious crime that demanded punishment and legitimized his rule.

The Spanish used a legal document called the "Requerimiento" to legitimize conquest. Before attacking, they read a history of the world and demanded submission to the Pope and Spanish King. Refusal provided a legal pretext for slaughter, a practice some Spaniards at the time considered absurd.

The vast majority of lands now considered the 'Muslim world,' including North Africa and the Middle East, were historically Christian territories taken by military conquest (jihad). The West often overlooks this long history of religiously motivated expansionism.

The English believed their string of improbable victories against a larger, richer France proved God's favor. They viewed their claim to the French throne not as aggression but as a divinely sanctioned right, using battlefield success as theological proof that their cause was just.

By casting their empire as a reflection of cosmic order, the Persians implicitly defined all outside peoples as living in a state of chaos and 'the lie.' This created an ideological justification for perpetual conquest, as bringing foreigners into the empire was framed as a moral duty to spread universal truth.

Facing widespread rebellions after a questionable rise to power, Darius used extreme, performative cruelty. The systematic mutilation and mass impalement of rebels were not random acts of rage but calculated displays of terror designed to crush dissent and establish his authority as absolute and unchallengeable.

While past rulers focused on pure conquest, Darius built enduring stability through meticulous administration, organizing tribute and fiscal policy. Though mocked by nobles as a mere 'shopkeeper,' this bureaucratic focus was as crucial as his military skill in sustaining the Persian empire for two centuries.

The perception of Christianity as purely passive is a modern distortion. Historically, concepts like "just war" and chivalry embodied an assertive, "muscular Christianity" that could be ferocious in defense of faith and civilization, a quality that is now lost.
