Peloponnesian War: The War

Britannica Schools

Peloponnesian War, (431–404 bce), war fought between the two leading city-states in ancient Greece, Athens and Sparta. Each stood at the head of alliances that, between them, included nearly every Greek city-state. The fighting engulfed virtually the entire Greek world, and it was properly regarded by Thucydides, whose contemporary account of it is considered to be among the world’s finest works of history, as the most momentous war up to that time.

A brief treatment of the Peloponnesian War follows. For full treatment, see Ancient Greek civilization: The Peloponnesian War.

The Athenian alliance was, in fact, an empire that included most of the island and coastal states around the northern and eastern shores of the Aegean Sea. Sparta was leader of an alliance of independent states that included most of the major land powers of the Peloponnese and central Greece, as well as the sea power Corinth. Thus, the Athenians had the stronger navy and the Spartans the stronger army. Further, the Athenians were better prepared financially than their enemies, owing to the large war chest they had amassed from the regular tribute they received from their empire.

Athens and Sparta had fought each other before the outbreak of the Great Peloponnesian War (in what is sometimes called the First Peloponnesian War) but had agreed to a truce, called the Thirty Years’ Treaty, in 445. In the following years their respective blocs observed an uneasy peace. The events that led to renewed hostilities began in 433, when Athens allied itself with Corcyra (modern Corfu), a strategically important colony of Corinth. Fighting ensued, and the Athenians then took steps that explicitly violated the Thirty Years’ Treaty. Sparta and its allies accused Athens of aggression and threatened war.

On the advice of Pericles, its most influential leader, Athens refused to back down. Diplomatic efforts to resolve the dispute failed. Finally, in the spring of 431, a Spartan ally, Thebes, attacked an Athenian ally, Plataea, and open war began.

The years of fighting that followed can be divided into two periods, separated by a truce of six years. The first period lasted 10 years and began with the Spartans, under Archidamus II, leading an army into Attica, the region around Athens. Pericles declined to engage the superior allied forces and instead urged the Athenians to keep to their city and make full use of their naval superiority by harassing their enemies’ coasts and shipping. Within a few months, however, Pericles fell victim to a terrible plague that raged through the crowded city, killing a large part of its army as well as many civilians. Thucydides survived an attack of the plague and left a vivid account of its impact on Athenian morale. In the meantime (430–429), the Spartans attacked Athenian bases in western Greece but were repulsed. The Spartans also suffered reverses at sea. In 428 they tried to aid the island state of Lesbos, a tributary of Athens that was planning to revolt. But the revolt was headed off by the Athenians, who won control of the chief city, Mytilene. Urged on by the demagogue Cleon, the Athenians voted to massacre the men of Mytilene and enslave everyone else, but they relented the next day and killed only the leaders of the revolt. Spartan initiatives during the plague years were all unsuccessful except for the capture of the strategic city Plataea in 427.

In the next few years the Athenians took the offensive. They attacked the Sicilian city Syracuse and campaigned in western Greece and the Peloponnese itself. In 425 the picture was bleak for Sparta, which began to sue for peace. But led by Brasidas, hero of the Battle of Delium, a Spartan force gained important successes in Chalcidice in 424, encouraging Athenian subject states to revolt. In a decisive battle at Amphipolis in 422, both Brasidas and the Athenian leader Cleon were killed. This set the stage for Cleon’s rival Nicias to persuade the Athenians to accept the Spartans’ offer of peace.

The so-called Peace of Nicias began in 421 and lasted six years. It was a period in which diplomatic maneuvers gradually gave way to small-scale military operations as each city tried to win smaller states over to its side. The uncertain peace was finally shattered when, in 415, the Athenians launched a massive assault against Sicily. The next 11 years made up the war’s second period of fighting. The decisive event was the catastrophe suffered by the Athenians in Sicily. Aided by a force of Spartans, Syracuse was able to break an Athenian blockade. Even after gaining reinforcements in 413, the Athenian army was defeated again. Soon afterward the navy was also beaten, and the Athenians were utterly destroyed as they tried to retreat.

By 411 Athens itself was in political turmoil. Democracy was overthrown by the oligarchical party, which was in turn replaced by the more moderate regime of the Five Thousand. At the end of 411 the rebuilt Athenian navy, fresh from several victories, acted to restore democratic rule. However, the democratic leaders refused Spartan peace offerings, and the war continued at sea with the Spartan and Athenian fleets trading costly victories. The end came in 405 when the Athenian navy was destroyed at Aegospotami by the Spartan fleet under Lysander, who had received much aid from the Persians. The next year, starved by an impenetrable blockade, Athens capitulated. Athens’ defeat was perhaps the worst casualty in a war that crippled Greek military strength, and thus the most culturally advanced Greek state was brought into final eclipse.

The Peloponnesian War was a war fought in ancient Greece between Athens and Sparta—the two most powerful city-states in ancient Greece at the time (431 to 405 B.C.E.). This war shifted power from Athens to Sparta, making Sparta the most powerful city-state in the region. The war featured two periods of combat separated by a six-year truce.

Athens and Sparta had previously quarreled in the decades prior to the war. One of Sparta’s allies, Corinth, had directly engaged the Athenian army. As a Spartan ally, Corinth resumed hostilities toward Athens when Athens threatened Corinth’s interests in the region surrounding Corcyra. This eventually drew Sparta into the conflict. The Spartan army began by raiding lands within an Athenian allied territory, particularly a region near Athens called Attica. The Athenians had built walls stretching from their seaport to the city of Athens. The walls helped protect Athens from direct assault, and its leader, Pericles, urged Athens not to engage in direct land battles with the Spartans. Instead, the Athenians used their navy to deliver troops into the Spartan territory to conduct raids on settlements.

After years of open warfare, Sparta offered peace and Athens accepted. The agreement was made official with the signing of the Peace of Nicias. The treaty stated that Athens and Sparta would defend each other for the next 50 years. However, the treaty only lasted six.

Hostilities resumed between Athens and Sparta with an assault launched by the Athenians at Sicily. Sparta decided to retaliate. Learning from its past experiences with the Athenian navy, they established a fleet of warships. It would be another decade of warfare before the Spartan general Lysander defeated the Athenian fleet at Aegospotami. This defeat led to Athenian surrender. As a result, the Peloponnesian War was concluded. Simultaneous to the end of this conflict came the end of the golden age of ancient Greece.

The Peloponnesian War between Athens and Sparta and their respective allies came in two stages: from c. 460 to 446 and from 431 to 404 BCE. With battles at home and abroad, the long and complex conflict was damaging to both sides. Sparta, with financial help from Persia, finally won the conflict by destroying the Athenian fleet at Aegospotami in 405 BCE.

The two most powerful city-states in ancient Greece, Athens and Sparta, went to war with each other from 431 to 405 B.C. The Peloponnesian War marked a significant power shift in ancient Greece, favoring Sparta, and also ushered in a period of regional decline that signaled the end of what is considered the Golden Age of Ancient Greece.
