DARIUS I THE GREAT
550 BC - 486 BC

Darius was king of Persia from 522 BC - 486 BC.

His family was the Achaemenid Dynasty.

When Darius wasn't busy with his many building projects, he tried to conquer Greece. He put down the Ionian Revolt.

In 493 BC, Darius seized Thracian Chersonese from Miltiades, who would pay him back for this later.

In 490 BC it was pay-back time. During the Greco-Persian Wars, Darius' army lost the Battle of Marathon.

Darius was the one who authored the inscriptions on the Behistun Rock.
