I want to know the answer to the following question:
What battle did Persia lose in 490 BC?
All the background I'm provided with is that "Attempts by some of the Greek city-states of Asia Minor to overthrow Persian rule failed, and Persia invaded the states of mainland Greece in 492 BC, but was forced to withdraw after a defeat at the Battle of Marathon in 490 BC.". Is that enough to answer the question?
