Peloponnesian War History & Facts
Where did the name Peloponnesian come from?
The Peloponnese, a peninsula in southern Greece, inspired the phrase “Peloponnesian.” Many of the great Greek city-states, such as Sparta, Argos, Corinth, and Messene, were located on this peninsula.
Before the War
Athens and Sparta had committed to a thirty-year peace following the Persian War. While they were striving to recover from the Persian War, they didn’t want to engage in conflict with one another. Under Pericles’ direction, Athens flourished in strength and prosperity during this time, and the Athenian empire expanded.
Sparta and its allies developed a growing sense of resentment and mistrust for Athens. Finally, Sparta declared war on Athens in 431 BC after the two cities found themselves on opposing sides of a struggle involving the city of Corinth.
The First War
Ten years passed during the first Peloponnesian War. At this period, the Athenians ruled the sea while the Spartans ruled the land. Long walls were constructed by Athens from the city to its harbour, Piraeus. They were able to continue trading and receiving supplies from their ships while remaining within the city because to this.
Even though the Spartans never managed to scale Athens’ defenses during the first war, the plague inside the city claimed many lives. This featured Athens’ legendary general and brilliant leader Pericles.

The Second War
The Spartans began to gather allies to conquer Athens. They even enlisted the help of the Persians who lent them money to build a fleet of warships. Athens, however recovered and won a series of battles between 410 and 406 BC.
Athens is Defeated
In 405 BC the Spartan general Lysander defeated the Athenian fleet in battle. With the fleet defeated, the people in the city of Athens began to starve. They did not have the army to take on the Spartans on land. In 404 BC the city of Athens surrendered to the Spartans.
The city-states of Corinth and Thebes wanted the city of Athens destroyed and the people enslaved. However, Sparta disagreed. They made the city tear down its walls, but refused to destroy the city or enslave its people.
