The Battle of Marathon was part of the First Persian War. Darius I of Persia sent an army to try and conquer Athens, but it was defeated.

Explanation:

The Battle of Marathon was the decisive battle that ended the First Persian War and the Persians' first attempt to conquer the Greek city states.

In August 490 BC a Persian expedition army landed on the advice of Hippias on the east coast of Attica, near the village of Marathon, a long walk from Athens. Under the charismatic leadership of Miltiades, the Athenians managed to thwart this attempt. According to high estimates, the Persians lost 6,000 to 7,000 men. On the other hand, "only" 192 Athenian warriors, whose remains were buried on the spot in a still existing burial mound.

According to a story from later times, the messenger Phidippides brought the news of the Greek victory in one go to Athens, where he died of exhaustion on arrival. It is probably a legend. Nevertheless, the Marathon run was introduced as a reminder when the modern Olympic Games were set up. Historically, the Athenian troops immediately returned to Athens at a rapid pace after the Persians' departure, a forced march of seven hours. They arrived on time to prevent a second landing attempt from the Persian fleet that had sailed around Cape Sunion.
