Sparta vs Athens

Greek hoplites holding the pass at Thermopylae

The two greatest cities of ancient Greece could hardly have been more different. Sparta was a militarised land power built around its feared army; Athens a democratic sea power of trade, culture and empire. They joined forces to beat Persia, then turned on each other in a long war that exhausted them both.

Key points

Sparta: the warrior state

Sparta organised its whole society for war. Its citizens trained as soldiers from boyhood1, supported by a large subject population of helots who worked the land. This produced the most respected heavy infantry in Greece, the men who held the pass at Thermopylae. But Sparta was conservative, suspicious of change and weak at sea, and its rigid system depended on keeping the helots down.

Athens: the democratic sea power

Athens took the opposite path. After the Persian Wars it built a maritime empire around the Delian League4, funded a great navy and developed the first large-scale citizen democracy (of adult male citizens), alongside an extraordinary flowering of drama, philosophy and art. Its power rested on its fleet and its walls5, which let it dominate the sea while sheltering behind fortifications on land, where Sparta was strongest.

From allies to enemies

The two cities led the Greeks to victory over Persia at Salamis and Plataea, but the alliance did not last. Athenian expansion alarmed Sparta, and in 431 BC the Peloponnesian War began.6 For a generation the land power and the sea power struggled to a standstill, until Sparta, backed by Persian gold, built a fleet and destroyed Athens' navy.7 Athens surrendered in 404 BC3, but the war left Greece exhausted and open to new powers.

The land power and the sea power fought to a standstill, and Greece paid the price.

The verdict

Sparta won the war, but neither side truly won the peace: a weakened Greece soon fell under the sway of Thebes and then Macedon.3 See the moments where the two cities stood together against Persia, from Thermopylae to Salamis, among the greatest battles of ancient Greece.

Frequently asked questions

What was the main difference between Sparta and Athens?

Sparta was a militarised land power ruled by a warrior elite, with the best infantry in Greece. Athens was a democratic sea power built on its navy, trade and culture. Sparta was strongest on land, Athens at sea.

Did Sparta and Athens ever fight together?

Yes. During the Persian invasions of 480-479 BC they led the Greek alliance together, Sparta leading on land at Thermopylae and Plataea (with Athenians in the line at Plataea), and Athens supplying the largest fleet at Salamis under a Spartan admiral. Their cooperation broke down in the decades that followed.

Who won the Peloponnesian War?

Sparta won. After nearly thirty years of war (431-404 BC), Sparta, financed by Persia and finally able to challenge Athens at sea, destroyed the Athenian fleet and forced Athens to surrender in 404 BC.

Did winning the Peloponnesian War make Sparta supreme?

Only briefly. The long war exhausted Greece, and Spartan dominance was soon broken by Thebes and then overshadowed by the rise of Macedon under Philip II and Alexander the Great.
