King Darius destroyed Miletus as punishment for the Ionian rebelling and defeated them in 493 B.C.E.
King Darius sent ambassadors to Greece to ask for Greek earth and water. If the Greek would do so, it would be a sign that they accepted Persian rule.

The Athenians and Spartans both killed the Persian ambassadors. In 490 B.C.E. King Darius sent about 15,000 foot soldiers and cavalry across the Aegean Sea to Greece for war.
