Question

Which factors contributed to the Greek victory against the 480-479 B.C.E. Persian invasion led by Xerxes?

Factor Contributing to Persia’s Defeat:
Not a Factor Contributing to Persia’s Defeat:

1. the unity of the Hellenic League

2. Athens’ new naval investments

3. Attica’s geography

4. the successful defense of Athens from Persian arson

Answer 1

1. the unity of the Hellenic League — Contributing.
Briefly: Spartan-led coordination (plus contributions from Athens, Corinth, etc.) allowed combined land and naval resistance (e.g., Plataea, Salamis).

2. Athens’ new naval investments — Contributing.
Briefly: Themistocles’ expansion of the Athenian trireme fleet gave the Greeks naval strength decisive at Salamis.

3. Attica’s geography — Contributing.
Briefly: The coast/islands (especially the narrow Straits of Salamis) and Greece’s overall broken, mountainous terrain favored Greek tactics and hampered Persian maneuvering.

4. the successful defense of Athens from Persian arson — Not a factor.
Briefly: Athens was sacked and burned in 480 BCE; the population and fleet had evacuated, so defense of the city itself was not a contributing cause of Persian defeat.
