Xerxes I and took part in the
second Persian invasion of Greece. In 480 and 479 BC, Mardonius spearheaded the Persian army's
destruction of Athens. Shortly thereafter, he was killed during the
Battle of Plataea.
Early and personal life

Mardonius was the son of
Gobryas, a Persian nobleman who had assisted the Achaemenid prince
Darius when he claimed the throne. The alliance between the new king and his friend was cemented by diplomatic marriages: Darius married Gobryas' daughter, and Gobryas married Darius' sister. Furthermore, Mardonius married Darius' daughter
Artozostra. Thus, Darius the Great was simultaneously Mardonius' uncle, father-in-law, and half-brother-in-law.
Military career
First Persian invasion of Greece
Darius appointed Mardonius as one of his generals and, after the
Ionian Revolt, sent him in 492 BC to retaliate against the Greek city-state of
Athens

for assisting the
Ionians. On his way to Athens, he used his army in the Ionian cities to depose the Greek
tyrants and set up
democratic governments, an action which surprised the Greeks at that time. Historians consider that he may have taken this action so that the Ionians would not revolt a second time after the Persian army had passed through. His fleet and army then passed across the
Hellespont.
Mardonius first attacked
Thasos, a Greek island which possessed gold mines. It became a tributary of the Achaemenid empire. The

and the army continued onto
Macedonia, which was soon added to the Persian Empire as a fully subordinate client kingdom, becoming also part of its administrative system.

However, after these victories, Mardonius’ fleet was destroyed in a storm off the coast near
Mount Athos. According to

. While Mardonius was wounded in the battle, he was victorious, re-subjugating Thrace into the empire.
Nevertheless, the loss of the fleet meant that he had to retreat back into
Asia Minor. He was relieved of his command by Darius, who appointed
Datis and
Artaphernes junior to lead the invasion of Greece in 490 BC, and though they were subsequently successful in capturing
Naxos and destroying
Eretria, they were later defeated at the
Battle of Marathon.
Second Persian invasion of Greece
Mardonius came back into favour under Darius' successor
Xerxes I, Mardonius' cousin and brother-in-law. Xerxes was at first not interested in renewing the war with Greece, but Mardonius, who had the most influence on Xerxes in all of Persia, repeatedly tried to convince him that he must avenge Darius' defeat. This view was opposed by another of Xerxes’ advisors,
Artabanus, who urged more caution in the matter. Herodotus, who portrays Mardonius as a somewhat evil adviser (as opposed to a number of other good advisers whose arguments are never followed), says that Mardonius simply wanted to become

(governor) of Greece and had a love for 'mischief and adventure'.
He was present at the
Battle of Thermopylae, and after the Persian defeat at the
Battle of Salamis, he attempted to convince Xerxes to stay and fight yet another campaign. This time Mardonius could not persuade Xerxes, but when Xerxes left he did become governor of those parts of Greece that had been conquered by the Persians. He subdued Macedon, ruled at that time by King
Alexander I, but Alexander himself gave valuable information about Mardonius' plans to the Athenians, saying that, as a Greek, he could not bear to see Greece defeated.
After the first part of the campaign directly under the orders Xerxes I, Mardonius remained in Greece with 300,000 elite troops, who fought in the last stages of the war, destroying

captured and sacked Athens, which had been deserted before the Battle of Salamis. He offered to return Athens and help rebuild the city if the Athenians would accept a truce, but the Athenians rejected the truce and prepared for another battle.
Battle of Plataea

Mardonius prepared to meet them at
Plataea, despite the opposition from another Persian commander,
Artabazus, who, like Artabanus, did not think that the Persian army could automatically defeat the Greeks. Mardonius was killed in the ensuing battle by the Spartans. It is claimed by

a Spartan called Aeimnestus killed Mardonius. This led to his army breaking up.
Herodotus relates of the Spartan leader Pausanias’ response when an Aeginetan suggests mounting on a pole the head of the slain Persian general Mardonius, as Xerxes had wanted to do to Leonidas after the battle of Thermopylae—a suggestion taken by Pausanias to threaten the very root of civilization: "Such doings befit barbarians rather than Greeks, and even in barbarians we detest them...Come not before me again with such a speech nor with such counsel, and thank my forbearance that you are not now punished".
