What was a significant result of the Peloponnesian War?

The significant result of the Peloponnesian War was the weakening of Athenian power. This conflict, fought between Athens and Sparta along with their respective allies, ultimately led to Athens suffering considerable losses both in military strength and in political influence. Following the war, Sparta emerged as a dominant power in Greece, while the once-mighty Athenian Empire found itself in a state of decline. The war not only depleted Athens' resources but also destabilized its political structure and diminished its maritime dominance.

This weakening allowed for shifts in power dynamics within the Greek world and set the stage for future conflicts, including those involving other rising powers such as Macedonia. The aftermath of the Peloponnesian War had profound implications for the political landscape of ancient Greece, which struggled with fragmentation rather than unity among the city-states, counter to what some other options suggest.
