The Persian Empire maintained control over its Greek subjects through indirect rule, propping up local strongmen known as 'tyrants.' These rulers were loyal to Persia because the empire was their sole source of power, making them effective but vulnerable puppets against a populace that resented them.

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.

Historically, rising and ruling powers don't stumble into war directly. Instead, their heightened distrust creates a tinderbox where a seemingly minor incident involving a third party (like the assassination in Sarajevo pre-WWI) can escalate uncontrollably into a catastrophic conflict.

The two dominant powers, Rome and Persia, engaged in a decades-long, civilization-shattering war that left both empires fiscally and militarily broken. This created a massive power vacuum, allowing newly unified Arab tribes to expand with astonishing speed into unguarded territories.

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 Greek revolt against Persia was not initially a noble quest for democracy. Its leader, Aristagoras, instigated it out of desperation after a failed military expedition left him broke and about to be dismissed by his Persian sponsors. He embraced democratic revolution as a last-ditch survival strategy.
