With what demand did they appear in the cities of Hellas after Darius the First?

They demanded from the Greeks land and water, that is, the subordination of the Greek city-states to Persia. However, not all Greek city-states accepted this offer, some of them refused and began a struggle against the Persian conquerors. Despite the advantage of the Persian Empire in military strength, the Greeks were still able to win this war. Especially ancient Athens distinguished itself here, which greatly rose in this war.
