Greco-Persian Wars

The Greco-Persian Wars (also often called the Persian Wars) were a series of conflicts between the Achaemenid Empire of Persia (modern day Iran) and Greek city-states that started in 499 BC and lasted until 449 BC. The collision between the fractious political world of the Greeks and the enormous empire of the Persians began when Cyrus the Great conquered the Greek-inhabited region of Ionia in 547 BC.
