The Battle of Marathon was the culmination of King Darius I of Persia’s first full scale attempt to conquer the remainder of Greece and incorporate it into the Persian Empire, which would secure the weakest portion of his western border.
The Greek victory over Darius I’s troops gave the Greek city-states confidence in their ability to withstand attacks. Therefore, the Battle of Marathon is considered a defining moment in European history. It was also one of the earliest recorded battles, described in detail by Herodotus.
