In the years leading up to the Peloponnesian War, Athens was becoming very powerful. They formed a military alliance called the Delian League, which included over 300 city-states. These members paid Athens for protection, making Athens quite influential. This worried Sparta, as they had their own alliance, the Peloponnesian League, and didn’t want Athens to become too dominant.
The tension between Athens and Sparta was already high when their allies, Megara and Corinth, went to war. Athens sided with Megara, while Sparta supported Corinth. This conflict marked the start of the Peloponnesian War. After fifteen years of fighting, Athens and Sparta agreed to the Thirty Years’ Peace, recognizing each other’s territories to avoid further conflict. However, this peace only lasted six years.
During the peace, Greece was still unstable. In 440 BC, Athens faced a rebellion from its ally, Samos. Sparta thought about breaking the treaty, but Corinth, a key Spartan ally, wanted to avoid war. Meanwhile, Corinth had its own issues with a rebellious colony, Corcyra, which sought help from Athens. This almost led to war between Athens and Corinth, but it was another Corinthian colony, Potidaea, that finally broke the peace.
Athens ordered Potidaea to remove its defenses and dismiss Corinthian officials. Corinth promised to help if Potidaea revolted, which it did, leading to the Battle of Potidaea. Although this violated the peace treaty, it was Athens’ later actions that escalated the conflict. By 432 BC, Athens imposed a trade ban on Megara, an ally of Sparta. Sparta demanded Athens lift the ban, but Athens refused, leading to a meeting of the Peloponnesian League. This meeting confirmed that Athens had broken the peace, leading to war.
The first phase of the war, called the Archidamian War, started in 431 BC. Athens had a strong navy, while Sparta had a powerful army. Sparta focused on land battles, capturing Athenian allies, while Athens used its navy to win battles at sea, like the Battle of Naupactus in 430 BC. However, a plague hit Athens, weakening its forces and causing fear among its allies.
After the plague and the death of the Athenian leader Pericles, Athens became more aggressive, resuming naval attacks. They had some successes, but Sparta soon invaded Amphipolis, an Athenian colony. By 421 BC, both sides wanted peace, leading to the Peace of Nicias, which lasted six years.
Tensions remained, and some Peloponnesian League members tried to form their own alliances, causing brief conflict. Sparta won the Battle of Mantinea, reasserting its power. The war reignited in 415 BC when Athens tried to help its allies in Sicily against Syracuse, which had ties to Sparta. The Athenian leader Alcibiades switched sides to Sparta, revealing Athenian plans. Despite initial setbacks, Sparta and its allies gained the upper hand.
The war continued until 405 BC, when Sparta, with help from Persia, built a strong navy and defeated Athens. This marked the end of Athenian naval dominance and established Sparta as the leading city-state. With Athens under control, the region changed significantly. Although Sparta won, many believed this marked the end of Greece’s Golden Age. Soon after, the Persian Empire regained its territories, and Philip II of Macedon further reduced Sparta’s power. While Sparta won the war, the consequences for Ancient Greece were significant and ultimately negative.

During the decades leading up to the conflict between Sparta and Athens, Athens was significantly increasing its strength and influence. A regional military alliance, known as the Delian League, was forming under Athenian control. At its peak, the Delian League had over 300 members, who paid tribute to Athens in exchange for military cooperation and protection against external threats, effectively creating an Athenian Empire. Sparta, observing this development, was understandably concerned. The rise of Athenian influence threatened Sparta’s own expansion goals. Conversely, Sparta was part of its own military alliance, the Peloponnesian League, which resembled the Delian League. This situation became increasingly problematic as the power dynamics between Sparta and Athens shifted, bringing the two city-states closer to conflict.
The relationship between Athens and Sparta was already strained when war broke out between their allies, Megara and Corinth. Since both Megara and Corinth were allied with Sparta, Athens seized the opportunity to intervene and form a new alliance with Megara, leaving Sparta to support Corinth. This marked the beginning of the first phase of the Peloponnesian War, which lasted fifteen years before a peace treaty was established. By the end of this period, Athens and Sparta recognized each other’s spheres of influence, leading to the signing of the Thirty Years’ Peace treaty, intended to prevent further conflict for three decades. However, this peace was short-lived, collapsing just six years later.
During the treaty’s duration, Greece remained unstable. By 440 BC, Athens faced a revolt from its ally, Samos, prompting Sparta to consider breaking the treaty. However, Corinth, a key ally of Sparta, opposed reigniting war with Athens. Consequently, the Peloponnesian League decided to adhere to the treaty and avoid involvement in the Athenian conflict. This decision proved wise, as Corinth soon faced its own challenges from a rebellious colony, Corcyra, which sought an alliance with Athens. This situation brought Athens and Corinth to the brink of war, but it was another Corinthian colony, Potidaea, that ultimately led to the breakdown of the Thirty Years’ Peace.
Potidaea, aligned with Athens, was ordered by Athens to dismantle its fortifications and dismiss Corinthian magistrates. Corinth responded by promising support if Potidaea revolted against Athens. When Potidaea did revolt, the Battle of Potidaea ensued, with Corinth sending forces to assist their ally. Despite this being a violation of the peace agreement, it did not immediately escalate tensions between Athens and Sparta. Instead, it was Athens’ subsequent actions that heightened the conflict.
By 432 BC, Athens was perceived by Sparta as overstepping its bounds. Athens imposed a trade embargo on Megara, which had reestablished its alliance with Sparta. Sparta’s demands for Athens to lift the embargo went unheeded, leading Corinth to request a congress of the Peloponnesian League to address their grievances against Athens. When the meeting occurred, a delegation from Athens attended, resulting in a tense atmosphere. Ultimately, it was clear that Athens had violated the peace, leading to war.
The first phase of this conflict, known as the Archidamian War, officially began in 431 BC. This war was characterized by an unusual dynamic: Athens had a strong navy but a less formidable land army, while Sparta had a powerful land force. The Spartans focused their efforts on land battles, capturing Athenian allies in Attica, while Athens utilized its naval superiority to conduct operations at sea, including a notable victory at the Battle of Naupactus in 430 BC. However, the war was soon interrupted by a devastating plague that struck Athens, significantly reducing its forces and causing fear among its allies.
With the war temporarily halted and the Athenian general Pericles deceased from the plague, Athens shifted to a more aggressive strategy, resuming naval operations against the Peloponnese. Despite initial successes, including the surrender of a Spartan force, Sparta quickly retaliated by invading Amphipolis, a colony of Athens. By 421 BC, both sides sought peace, resulting in the signing of the Peace of Nicias, which brought six years of relative stability.
However, tensions remained as some members of the Peloponnesian League attempted to form their own coalition, leading to conflict between Sparta and its former allies. This internal strife was short-lived, as Sparta emerged victorious in the Battle of Mantinea, reestablishing its dominance.
The conflict with Athens reignited in 415 BC when Athens received a request for assistance from its Ionian allies in Sicily, who were threatened by Syracuse, a city with ethnic ties to Sparta. An expedition led by Alcibiades was dispatched, but upon arrival, he was ordered to return to Athens for trial. Fearing an unfair trial, Alcibiades defected to Sparta, revealing Athenian plans in Sicily. Despite initial setbacks for Athens, the Peloponnesian League, including Sparta, intervened, ultimately gaining the upper hand.
The war continued until 405 BC, when Sparta, with financial and logistical support from the Persian Empire, built a formidable navy that decisively defeated the Athenian fleet. This victory shocked Greece, marking the end of Athenian naval supremacy and establishing Sparta as the dominant city-state.
With Athens under strict control and tribute to Sparta, the region underwent significant changes. While Sparta addressed the issue of Athenian dominance, many believed this marked the decline of the Golden Age of Ancient Greece. Shortly after Sparta’s victory, the Persian Empire would reclaim its territories, and Philip II of Macedon would further diminish Sparta’s power. Thus, while Sparta may have triumphed in battle, the broader implications for Ancient Greece were profound and ultimately detrimental.
