The Battle of Salamis was a naval battle fought in 480 BC during the Second Persian Invasion of Greece. It took place in the straits between the island of Salamis and the mainland. The Greek fleet, led by Themistocles, faced the much larger Persian navy commanded by King Xerxes. The Greeks used their knowledge of the local waters to outmaneuver the Persians, resulting in a decisive victory. This battle was crucial in the Greco-Persian Wars, as it marked a turning point in the conflict. The defeat of the Persian fleet weakened their naval power and boosted Greek morale, ultimately leading to the eventual Greek victory in the war.
