Step-by-step explanation:
The outcome of the Persian Wars was a major victory for Greece. The Persian Wars were a series of conflicts between Greece and the Persian Empire from 499 BCE to 449 BCE. Despite being initially outnumbered, the Greek city-states, led by Sparta and Athens, were able to defeat the Persians. The victories at the battles of Marathon, Thermopylae, and Salamis were significant turning points in favor of the Greeks, ultimately leading to the Persian retreat and the liberation of Greek city-states.
