Final answer:
The major battles of the Persian Wars include the Battle of Marathon, the Battle of Thermopylae, the Battle of Salamis, and the Battle of Plataea. To identify a battle that was not a major part of the Persian Wars, one would need to look beyond these well-documented clashes.
Step-by-step explanation:
The question asks which of the following was not a major battle of the Persian Wars. Major battles during the Persian Wars include the Battle of Marathon in 490 BCE, where the Athenians defeated the Persians; the Battle of Thermopylae in 480 BCE, known for the heroic stand of the Spartans; the naval Battle of Salamis also in 480 BCE, where the Greek navy achieved a decisive victory against the Persians; and the Battle of Plataea in 479 BCE, where the Greek coalition forces led by the Spartans effectively ended Persian land military ambitions in Greece.
To answer which was not a major battle of the Persian Wars, one would have to consider other battles outside of these events. Without a list of battles to choose from, the discussion is limited to the recognition of these aforementioned key battles as major clashes during the Greek-Persian conflict.
