The Greco-Persian Wars were a series of massive military conflicts. They involved the Achaemenid Empire and various Greek city-states. These wars lasted from 499 BC until 449 BC. The conflict was a collision between two very different worlds. The Persians managed a massive, unified empire. In contrast, the Greeks lived in many small, independent cities.

The roots of the war began in 547 BC. During this time, Cyrus the Great conquered Ionia. Ionia was a region in Asia Minor inhabited by Greeks. To maintain control, the Persians appointed tyrants to rule these cities. This political setup caused great tension. In 499 BC, a leader named Aristagoras started the Ionian Revolt. He incited the cities of Hellenic Asia Minor to rebel against Persian rule. Athens and Eretria sent military support to help the rebels. In 498 BC, these forces captured and burned the Persian capital of Sardis.

King Darius the Great sought revenge for the destruction of Sardis. The Ionian Revolt continued with a stalemate for several years. However, the Persians regrouped and attacked Miletus in 494 BC. The Ionians suffered a decisive defeat at the Battle of Lade. This caused the rebellion to collapse completely. Darius then planned to conquer mainland Greece. He wanted to secure his empire from future revolts. He also wanted to punish Athens and Eretria for their interference.

The first Persian invasion began in 492 BC. The general Mardonius successfully re-subjugated Thrace and Macedon. However, various mishaps ended this campaign early. In 490 BC, a second force arrived via the Aegean Sea. Commanders Datis and Artaphernes led this expedition. They captured and razed the city of Eretria. When they moved to attack Athens, they met the Athenian army. The Persians were decisively defeated at the Battle of Marathon. This event temporarily halted Persian expansion into Greece.

After Darius died in 486 BC, his son Xerxes took command. Xerxes led a massive second invasion in 480 BC. He assembled one of the largest ancient armies ever seen. The Persians won at the Battle of Thermopylae. This victory allowed them to overrun much of Greece. They even burned the evacuated city of Athens. However, the Persian momentum shifted at sea. The Greeks won a severe victory at the Battle of Salamis.

The Greeks then went on the offensive. They achieved a decisive victory at the Battle of Plataea. This victory ended the Achaemenid invasion of Greece. The Greeks also destroyed the Persian fleet at the Battle of Mycale. Following these wins, Ionia and Macedon regained their independence. To stay safe, many Greeks formed the Delian League. This was a confederation led by Athens. They campaigned against Persia for thirty more years. They won a major victory at the Battle of the Eurymedon in 466 BC.

We learn about these events through ancient historians. Herodotus is the most important source. He was born in 484 BC in Halicarnassus. He is often called the "Father of History." He wrote his "Histories" to trace the origins of the wars. He tried to use explanations he could personally verify. Later, the historian Thucydides also wrote about this era. He is considered a very reliable primary account. Archaeologists have found physical evidence of the wars too. For example, they found Persian arrowheads at Thermopylae.
