The Battle of Thermopylae was not fought by 300 Spartans alone. This breakdown clarifies the actual scale of the Greek defense.

Popular culture often simplifies the conflict down to a tiny group of warriors standing against an empire. While the legend of the 300 Spartans is compelling, historical evidence indicates that several thousand Greeks from multiple city-states were stationed at the mountain pass. This video examines why the myth of the 300 Spartans persists despite the involvement of a much larger coalition.

We also analyze the Persian army size. Historical accounts of these massive invading forces are frequently debated by modern historians, and this analysis suggests those numbers may be significantly exaggerated. Understanding the real logistics of the ancient world provides a clearer picture of what actually happened during those three days.
