Darius the Great (c. 549 BC– 486/485 BC) was the son of Hystaspes and Persian Shah of Iran from 522 BC to 485 BC. After Darius became Shah of Persia, he divided the Persian Empire into twenty provinces, and appointed a governor for each province.

He tried to conquer Greece and subjugate the Greeks in the first Greco–Persian war but lost at the Battle of Marathon.
