The series of conflicts fought between the Greek city-states and the Achaemenid Persian Empire from the Ionian Revolt of 499 BCE through the failed Persian invasions of the Greek mainland led by Darius I in 490 BCE and by his son Xerxes I in 480 to 479 BCE. The mainland campaign of Xerxes brought the defense of the pass at Thermopylae, the evacuation and burning of Athens, the decisive Greek naval victory at Salamis and the land victory at Plataea the following year, after which fighting continued intermittently in the Aegean and Asia Minor for decades. Herodotus's Histories, written a generation later, is the principal connected narrative for the wars and the source for most of what is known about the oracles the Greek states consulted before and during them, Delphi's included.
Facts
Consequences
What It SettledSourced to the subject's own accountThe war wound down after the Greek-led Delian League cleared Persian forces from Ionia and Cyprus; a Greek fleet sent to Cyprus in 451 BC achieved little, and the war drew to a quiet close shortly after. 2 Religious DimensionXerxes's advance to Thermopylae in August 480 BC coincided with the Olympic Games and the festival of Carneia; Spartan religious custom held that making war during those festivals was sacrilegious, which shaped when Sparta's main army could march. 2 Sourced to the subject's own accountThis atlas records no death toll for the Greco-Persian Wars. The Greek states' repeated consultation of Delphi before and during the campaign, including the two Athenian responses of 481 BCE naming Salamis, was ordinary practice for nearly every Greek state at war in this period, not a mark that the war was fought over religious difference. The war was a Persian imperial campaign of conquest against the Greek city-states and a Greek war of defense against it, fought over territory and political control rather than religion.

Death Toll AssessmentNo scholarly synthesis totals the Greco-Persian Wars' dead. Herodotus records figures for Marathon, Thermopylae, Salamis, Plataea and Mycale, but modern historians regard many of his numbers, including the size of the Persian invasion force itself, as unreliable, and no revised total has been produced.
Herodotus's Histories is the main narrative source and gives casualty figures for the war's major engagements, but modern classical historians treat those figures, and the Persian troop strengths behind them, with heavy skepticism. No scholarly total built from revised figures was found. The Event

From the Ionian Revolt to the Battles That Stopped Persia
This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.
The Greco-Persian Wars were a series of conflicts fought between the Greek city-states and the Achaemenid Persian Empire from the Ionian Revolt of 499 BCE through the failed Persian invasions of the Greek mainland led by Darius I in 490 BCE and by his son Xerxes I in 480 to 479 BCE. The mainland coalition was led chiefly by Athens and Sparta, whose forces met the invading Persian army and navy at a series of decisive engagements across a single crowded decade of campaigning. Xerxes's campaign brought the defense of the pass at Thermopylae, the evacuation and burning of Athens, the decisive Greek naval victory at Salamis, and the land victory at Plataea the following year.
Persia withdrew from the Greek mainland after Salamis and Plataea, though the wider war continued at sea and in Asia Minor for several more decades before ending in Greek favor around 449 BCE. Herodotus's Histories, written a generation later, is the principal connected narrative for the wars and the source for most of what is known about them, including the oracles the Greek states consulted before and during them.
Oracles, Omens and an Uncertain Death Toll
This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.
No scholarly synthesis totals the Greco-Persian Wars' dead across the full half-century of conflict, from the Ionian Revolt through the last engagements in Asia Minor decades later. Herodotus records figures for Marathon, Thermopylae, Salamis, Plataea and Mycale, but modern historians regard many of his numbers, including the reported size of the Persian invasion force itself, as unreliable, and no revised total reconciling the individual battles into one war-wide figure has ever been produced by later scholarship on the wars.
The Greek states repeatedly consulted the oracle at Delphi before and during the mainland invasion, most consequentially the two Athenian responses of 481 BCE naming Salamis directly as the place where the invasion would be decided. Both sides also read omens and portents through the campaign, and later suspicion that Delphi had made its own accommodations with the advancing Persian court shadowed the oracle's reputation for a full generation afterward, a suspicion later writers attached squarely to the priesthood administering the shrine rather than to the god it served.

What Was the Total Death Toll of the Greco-Persian Wars?
Herodotus's Histories records casualty figures for individual engagements, Marathon, Thermopylae, Salamis, Plataea and Mycale among them, but modern scholars regard many of the ancient figures, including the size of the Persian invasion force itself, as unreliable and often inflated. No modern scholarly synthesis was located that totals deaths across the wars' span into a single figure; scholarship instead discusses each battle's own contested numbers on its own terms.
What would resolve this A modern scholarly total built from revised, rather than Herodotus's own, troop and casualty figures across the wars' major engagements, or a demographic study of Achaemenid and Greek population loss over the conflict. No such synthesis was located.
