Development of the Battle of Thermopylae

The Persian troops crossed the Strait of the Dardanelles (ancient Hellespont) using two floating bridges. Then they occupied Thrace and Macedonia and invaded Hellas from the north. However, to be able to enter the country of the Greeks they had to cross the Thermopylae gorge , also called Hot Gates, because there were hot springs there.

In the V century a. This gorge consisted of a pass about 100 meters wide, between the slopes of the mountains and a cliff with an almost straight fall towards the Aegean Sea. That narrow place was chosen by the Greeks to stop the invading forces from passing by , since it canceled out the numerical difference and prevented them from being overtaken by the flanks.

At the same time, and so that the Persians could not disembark with their troops south of Thermopylae, the Greek fleet blocked the passage of the Asian navy in the Strait of Artemisium.

Once at Thermopylae, Xerxes sent emissaries to try to convince Leonidas to surrender, but the Spartan king rejected all the offers made by the Persians.

Xerxes launched several waves of invaders one after another, but all were repulsed by the Greeks. They fought in close formation, side by side, brandishing long spears with their right hand and holding bronze shields with their left. The Persians fought with small wicker shields and shorter spears. Thrown on the run, they crashed into an impenetrable wall of shields and pointed spears.

The Persian victory was possible due to the betrayal of a GreekEphialtes of Thessaly , who led the Persians through a little-known trail that put the Asians in the rear of the defenders. Seeing himself surrounded, Leonidas ordered the flight of the allies and prepared to resist with his three hundred Spartans. It also had about 1,000 men who refused to leave.

Taken front and back, the Greeks were finally defeated and slaughtered with a hail of Persian arrows .

Causes and consequences of the Battle of Thermopylae


The causes of the Battle of Thermopylae were the following:

  • The defeat suffered by the Persians in the first medical war, the Battle of Marathon , which was a great humiliation for the Persian Emperor Darius I.
  • The desire of Xerxes I to avenge the defeat suffered by the imperial troops, in addition to subduing the Greeks and extending their dominions across the Balkan peninsula . Xerxes had ascended the throne in 486 BC. C. and was the son of Dario I and Atosa, daughter of Ciro the Great, founder of the Persian Empire .
  • The firm decision of the Greek polis to defend their independence and freedom and prevent their country from becoming part of the Persian Empire.
  • The execution of the Persian ambassadors in Athens and Sparta . In 481 a. C., Xerxes had sent emissaries to all the cities of Hellas to demand the delivery “of the water and the earth” like symbol of submission to their authority. Most of the Greek cities accepted this demand. The Athenians, on the other hand, tried the Persian ambassadors, sentenced them to death, and executed them. In Sparta, King Leonidas had them thrown into a well without any process. Xerxes considered the murder of his emissaries a declaration of war.

Importance of the Battle of Thermopylae

The sacrifice at Thermopylae of Leonidas and the 300 Spartan hoplites endured over time as a symbol of the struggle for the defense of freedom, and of how discipline and proper use of the land could act as multiplier effects of the performance of a small army. , but well trained and with high morale.
