Who was the Persian king that fought against the Greeks at the battles of salamis and Marathon?

Answer 1

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.

Answer 2

At the time of the land battle of Marathon in 490 BCE the Persian king was Darius the Great. He himself did not attend as it was only a punitive expedition he sent.

At the naval battle of Salamis in 480 BCE it was Darius' successor Xerxes the Great, who watched this naval battle from a hill overlooking the Salamis Strait.

Answer 3

He did not invade Greece. King Darius the Greatsent a punitive amphibious expedition in 490 BCE against the city-states of Eretria and Athens for their 498 BCE participation in supporting the Ionian Revolt in Asia Minor, during which the Athenians burnt the gods at his provincial capital of Sardis. The expedition captured Eretria, but was defeated when it landed at Marathon to attack Athens, and returned home.

Answer 4

King Darius I. When he was trying to punish Greece for not bowing to his will, he decided to invade. He was finally defeated at the Battle of Marathon.

Answer 5

Darius the Great.
