As part of the ongoing war which went from 499 to 449 BCE, the Persians mounted a punitive expedition against Eretria and Athens for supporting the revolt of Greek city-states in Asia Minor. The expedition captured Eretria but was turned back at the battle of Marathon.
Everyone seems to be convinced that there was only one Persian War, when in fact there were two. The first was in 490 BC as Darius I of Persia attempted to invade Greece. The second was in 480 and 479 BC as his son Xerxes invaded Greece.
Another view:
The invasion of 490 was a limited punitive expedition directed against two cities only of the many cities in Greece - Athens and Eritea - for interfering in the Persian empire by supporting rebellions there by Greek cities within the empire. It was not Greece which was invaded. The object was to install Persian sympathisers to rule the two cities who would prevent further interference.
This failed, so the Persians decided to bring all of the mainland Greek cities within the Persian empire and so establish an ethnic fronter to stop ongoing external interference in the peace within the empire. In 480 it was a general invasion to achieve that result.
Incidentally, there were many wars involving the Greek worl and Persia over 200 years, terminated by Alexander's conquest of the Persian empire in the late 3rd Century BCE.
There were two Persian Wars, both won by the Greeks because the Persians were induced to leave. The Athenian general Miltiades won the first war at the Battle of Marathon in 490 BC. Ten years later the second war began, and it was won by the Spartan king Pausanias at the Battle of Plataea in 479 BC.
The Ionian Revolt - a revolt by the Greek city-states against Persian rule.

The Ionians (The city-states of Ionia.) revolted , 499 BC to 449 BC , against the Persians .
Historians today think the 1st Persian war started around 490 BC.
There were two Persian Wars, recorded by the Greek historian Herodotus. The first was in 490 BC, and the second was in 480-479 BC. If the question is about the Persian Gulf War, it was in 1990-91.
The Persian Wars lasted from 499-448 BC. The Pelopenesian Wars lasted from 431-404 BC So the answer is: The Persian Wars happened first.
