To this end, he sought alliance with the Lacedæmonians; but they would have nothing to do with him, deeming the venture too remote. Then he went to Athens, whence the sons of Pisistratus had been driven forth just before. For Hipparchus had been slain by Harmodius and Aristogiton, and afterwards Hippias would hardly have been expelled but that his enemies captured his children and so could make with him what terms they chose. But the Pisistratidse having been expelled, the city grew in might, and changes were made in the government of it by Cleisthenes the Alcmæonid. But the party that was against Cleisthenes got aid from Cleomenes of Sparta; yet the party of Cleisthenes won. Then, since they reckoned that there would be war with Sparta, the Athenians had sought friendship with Artaphernes at Sardis; but since he demanded earth and water they broke off. But because Athens was waxing in strength, the Spartans bethought them of restoring the despotism of the Pisistratidæ. But Sosicles, the Corinthian, dissuaded the allies of Sparta from taking part in so evil a deed. Then Hippias sought to stir up against the Athenians the ill-will of Artaphernes, who bade them take back the Pisistratidæ, which they would not do. Therefore, when Aristagoras came thither, the Athenians were readily persuaded to promise him aid. And he, having gathered the troops of the Ionians, who were at one with him, marched with them and the Athenians against Sardis and took the city, which by a chance was set on fire. But after that the Athenians refused further help to the Ionians, who were worsted by the Persians. But the ruin of the Ionians was at the sea-fight of Lade, where the men of Chios fought stoutly; but they of Samos and Lesbos deserting, there was a great rout. _IV.--Marathon and Thermopylæ_ Thereafter King Darius, being very wroth with the Athenians for their share in the burning of Sardis, sent a great army across the Hellespont to march through Thrace against Athens, under his young kinsman Mardonius. But disaster befell these at the hands of the Thracians, and the fleet that was to aid them was shattered in a storm; so that they returned to Asia without honour. Then Darius sent envoys to demand earth and water from the Greek states; and of the islanders the most gave them, and some also of the cities on the mainland; and among these were the Aeginetans, who were at feud with Athens. But of those who would not give the earth and water were the Eretrians of Eubcea. So Darius sent a great armament by sea against Eretria and Athens, led by Datis and Artaphernes, which sailed first against Eretria. The Athenians, indeed, sent aid; but when they found that the counsels of the Eretrians were divided, so that no firm stand might be made, they withdrew. Nevertheless, the Eretrians fought valiantly behind their walls, till they were betrayed on the seventh day. But the Persians, counselled by Hippias, sailed to the bay of Marathon.
