Peloponnesian War

The Peloponnesian War (431-404 BCE) was a significant conflict in ancient Greece, fought between two major alliances: the Delian League led by Athens and the Peloponnesian League led by Sparta. The war stemmed from power struggles and economic competition following the Persian Wars. It featured notable events like the Athenian plague and the Sicilian Expedition, ultimately leading to Athens' defeat. The war profoundly impacted Greek society, diminishing Athenian power and altering the political landscape, paving the way for the rise of Sparta and later the overall decline of Greek independence.
