Greek City-States Timeline

(c. 800 BCE – 338 BCE)

Greek city-states, known as poleis, were independent political units that flourished across the Aegean world from roughly 800 BCE until their absorption into larger empires. Each polis had its own government, laws, army, and culture, ranging from the democratic Athens to the militaristic Sparta. These fiercely independent communities drove remarkable achievements in philosophy, art, science, and politics, while also engaging in frequent wars with one another, most notably the Peloponnesian War.

Rise of the Polis

Mycenaean civilization collapses

1100 BC

The collapse of Mycenaean palace civilization around 1100 BC ushered in the Greek Dark Ages. Writing was lost, trade declined, and populations dispersed, setting the stage for the gradual emergence of small, independent communities that would eventually develop into the Greek city-states.

Athens and Sparta

Ionian Revolt against Persia begins

499 BC - 493 BC

Greek city-states in Ionia, led by Miletus, revolted against Persian rule in 499 BC. Athens and Eretria sent ships to aid the rebels, and although the revolt was crushed by 493 BC, it provoked Persian retaliation and set the stage for the Greco-Persian Wars.

Battle of Marathon

Second Athenian League founded

378 BC
