<Li> Wars of the Delian League </Li> <P> The Greco - Persian Wars (also often called the Persian Wars) were a series of conflicts between the Achaemenid Empire of Persia 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 . Struggling to rule the independent - minded cities of Ionia, the Persians appointed tyrants to rule each of them . This would prove to be the source of much trouble for the Greeks and Persians alike . </P> <P> In 499 BC, the tyrant of Miletus, Aristagoras, embarked on an expedition to conquer the island of Naxos, with Persian support; however, the expedition was a debacle and, preempting his dismissal, Aristagoras incited all of Hellenic Asia Minor into rebellion against the Persians . This was the beginning of the Ionian Revolt, which would last until 493 BC, progressively drawing more regions of Asia Minor into the conflict . Aristagoras secured military support from Athens and Eretria, and in 498 BC these forces helped to capture and burn the Persian regional capital of Sardis . The Persian king Darius the Great vowed to have revenge on Athens and Eretria for this act . The revolt continued, with the two sides effectively stalemated throughout 497--495 BC . In 494 BC, the Persians regrouped, and attacked the epicentre of the revolt in Miletus . At the Battle of Lade, the Ionians suffered a decisive defeat, and the rebellion collapsed, with the final members being stamped out the following year . </P> <P> Seeking to secure his empire from further revolts and from the interference of the mainland Greeks, Darius embarked on a scheme to conquer Greece and to punish Athens and Eretria for the burning of Sardis . The first Persian invasion of Greece began in 492 BC, with the Persian general Mardonius successfully re-subjugating Thrace and conquering Macedon before several mishaps forced an early end to the rest of the campaign . In 490 BC a second force was sent to Greece, this time across the Aegean Sea, under the command of Datis and Artaphernes . This expedition subjugated the Cyclades, before besieging, capturing and razing Eretria . However, while en route to attack Athens, the Persian force was decisively defeated by the Athenians at the Battle of Marathon, ending Persian efforts for the time being . </P>
