The Battle of Marathon, fought in 490 BC, is considered the turning point in the Greco-Persian Wars, where the outnumbered Athenian forces defeated the Persian army. This significant victory not only boosted Greek morale but also demonstrated the effectiveness of the hoplite-style warfare used by the Greeks. The battle showcased the courage of the Athenian soldiers and highlighted the importance of unity among the Greek city-states in resisting Persian domination. The triumph at Marathon became a source of inspiration for future Greek resistance against Persia and laid the foundation for subsequent victories, including those at Salamis and Plataea.
