He realised that this failed attempt to take over Eretria and Athens would encourage othe Greek city-states to intervene in his empire so he determined to bring all the mainland Greek city-states under control of a Persian provincial governor. He bribed some of the cities to agree to this, and planned to mount an expedition to bring the rest under control. He died before he could do this and left it to his son and successor King Xerxes. His attempt failed at the battles of Salamis, Plataea and Mycale in 480-479 BCE.
Athens and its ally Plataia defeated the Persian expeditionary force sent out by King Darius at Marathon in 490 BCE.
Darius I .
The name of the King that was fighting in the battle of the Marathon was Leonidas. I am not sure which King you are talking about, but this is Athens King.Reality:Leonidas was not present at Marathon since he is the king of Sparta and they(the spartan army) arrived late for the battle due to a festival. Athens was a democracy so it had no king. The only king that might have been present was the king of Plataea(the only greek city who helped athens) but history seem to have forgotten his name.Addendum:True, there were no kings at Marathon. Perhaps the first answerer is confusing it with the fight at Thermopylae ten years later, when the Spartan king Leonidas led the defence of the pass, or the battle of Plataea eleven years later when there were two kings present - Pausanias king of Sparta and Xerxes king of Persia.
