What was a significant outcome of the Persian Wars?

The significant outcome of the Persian Wars was the unification of the Greek city-states against Persia. During these conflicts, which included notable battles such as Marathon and Salamis, the various Greek city-states recognized a common enemy in the Persian Empire, prompting a sense of solidarity among them. This unprecedented unity allowed many city-states, previously divided and often in competition or conflict with one another, to collaborate effectively in a military context. The success against Persia not only fostered a sense of Greek identity but also established a precedent for future cooperation among the city-states, ultimately laying some groundwork for the political and cultural developments that would follow in classical Greece.
