He captured Athens and looted the city in 480-479 BCE.
A punitive expedition he sent to Eretria and Athens was defeated by Athens at Marathon 490 BCE.
Darius I of Persia sought to fight Athens primarily because of their support for the Ionian Revolt against Persian rule. The Athenians had provided military assistance to the Ionian city-states, which angered Darius and threatened his authority. Additionally, subduing Athens would enhance Persian dominance in the region and serve as a warning to other Greek city-states about the consequences of defiance. Ultimately, Darius aimed to expand his empire and secure Persian interests in the Mediterranean.
Battle of Marathon
Xerxes was heir to Darius. What 'advice about him' means in this context I can't fathom.
No, it was a punitive expedition launched by Darius I against not the Greeks generally but Eretria and Athens. Eretria was captured and enslaved but Athens defeated the attack on it at Marathon and in front of the city in 490 BCE. Cyrus the Great was killed in a battle with the Massagetae the previous century and was subsequently succeeded by his son Cambyses II.
There were three kings of Persia called Darius in the 6th, 5th and 4th Centuries BCE. Greece was not a unified country - the Greek world was comprised of 2,000 independent city-states, including Sparta, Thebes, Corinth, Athens. So there was no capital of the Greek world.
First it was Darius the Great, and after he died it was taken on by his son Xerxes.
