context_page_description: Demaratus, or Demaratos, was a king of Sparta from around 515 BC until 491 BC, 15th of the Eurypontid line, successor to his father Ariston. As king, he is known chiefly for his opposition to the co-ruling Spartan king, Cleomenes I. He later fled to Achaemenid Persia where he was given asylum and land, and fought on the Persian side during the Second Persian invasion of Greece.
context_section_description: When Cleomenes attempted to make Isagoras tyrant in Athens, Demaratus tried unsuccessfully to frustrate his plans.  In 491 BC, Aegina was one of the states which gave the symbols of submission (earth and water) to Persia.  Athens at once appealed to Sparta to punish this act of medism, and Cleomenes I crossed over to the island to arrest those responsible.  His first attempt was unsuccessful, due to interference from Demaratus, who did his utmost to bring Cleomenes into disfavour at home.
  In retaliation, Cleomenes urged Leotychidas, a relative and personal enemy of Demaratus, to claim the throne on the grounds that the latter was not really the son of Ariston, but of Agetus, his mother's first husband.  Cleomenes  bribed the Delphic oracle to pronounce in favour of Leotychidas, who became king in 491 BC.
  After the deposition of Demaratus, Cleomenes visited the island of Aegina for a second time, accompanied by his new colleague Leotychides, seized ten of the leading citizens and deposited them at Athens as hostages.
  On his abdication, Demaratus was forced to flee. He went to the court of the Persian king Xerxes I, who gave him the cities of Teuthrania and Halisarna around Pergamum, where his descendants Eurysthenes and Procles  still ruled at the beginning of the 4th century BC.
  He accompanied Xerxes I on his invasion of Greece in 480 BC and is alleged to have warned Xerxes not to underestimate the Spartans before the Battle of Thermopylae:
  The same goes for the Spartans. One-against-one, they are as good as anyone in the world. But when they fight in a body, they are the best of all. For though they are free men, they are not entirely free. They accept Law as their master. And they respect this master more than your subjects respect you. Whatever he commands, they do. And his command never changes: It forbids them to flee in battle, whatever the number of their foes. He requires them to stand firm -- to conquer or die. O king, if I seem to speak foolishly, I am content from this time forward to remain silent. I only spoke now because you commanded me to. I do hope that everything turns out according to your wishes.
  — Herodotus vii (trans. G. Rawlinson)
  Xerxes I also asked Demaratus about his knowledge of the Greeks and if they will put up a fight against the Persian army. In response Demaratus speaks favourably about the Greeks even after being deposed and exiled from Sparta:
  So Demaratus said, 'my lord, you have asked me to tell the whole truth—the kind of truth that you will not be able to prove false at a later date. There has never been a time when poverty was not a factor in the rearing of the Greeks, but their courage has been acquired as a result of intelligence and the force of law. Greece has relied on this courage to keep poverty and despotism at bay. I admire all the Greeks who live in those Dorian lands, but I shall restrict what I have to say to the Lacedaemonians alone. First, then, there's no way in which they will ever listen to any proposals of yours which will bring slavery on Greece; second, they will certainly resist you, even if all the other Greeks come over to your side. As for the size of their army, there's no point in your asking how, in terms, of numbers, they can do this. If there are in fact only a thousand men to march out against you (though it may be fewer or it may be more), then a thousand men will fight you.'
  — Herodotus vii (trans. Robin Waterfield)
  Greek exiles in the Achaemenid Empire
  Demaratus was one of several Greeks aristocrats who took refuge in the Achaemenid Empire following reversals at home, other famous ones being Themistocles and Gongylos. In general, they were generously rewarded by the Achaemenid kings, and received land grants to support them, and ruled over various cities in Asia Minor.
