"Three Hundred" refers to a famous battle fought in 480 BC during the Greco-Persian Wars. It involved a small Greek force, led by King Leonidas I of Sparta, who defended the narrow pass at Thermopylae against a much larger Persian army commanded by King Xerxes I. The battle is celebrated for the bravery and sacrifice of the 300 Spartan warriors who fought valiantly despite overwhelming odds. The story of "Three Hundred" has been popularized in modern culture, particularly through the graphic novel and film titled "300". These adaptations highlight themes of heroism, loyalty, and the struggle for freedom, while also dramatizing the historical events surrounding the battle.
