In 413 BCE, during the Peloponnesian War, Sparta, with Persian support, constructed a naval base at Decelea. This audacious move aimed to disrupt Athenian supply routes, impose a two-front war, and shift the balance of power, altering the course of the conflict in ancient Greece.
The Peloponnesian War
The Peloponnesian War, which spanned from 431 to 404 BC, was a protracted conflict between the two powerful Greek city-states of Athens and Sparta, along with their respective allies. The war had already witnessed significant battles, political maneuvering, and shifting alliances, and by 413 BC, it was clear that it would be a long and grueling struggle.

Strategic Objectives
Sparta, recognizing that its land-based forces alone might not be sufficient to defeat Athens, decided to employ a maritime strategy. The construction of a naval base at Decelea, a location in the Athenian territory, was a bold and calculated move. This base would serve multiple strategic objectives.
Disrupting Athenian Supplies
One of the primary aims of the Spartan naval base was to disrupt the flow of supplies to Athens, which relied heavily on its access to the sea. By establishing a presence in Athenian territory, Sparta could threaten the vital grain supply routes from the Black Sea. Weakening Athens’ food security and thereby its military capability.
Forcing a Two-Front War
Sparta aimed to weaken Athens through pressure on two fronts. By occupying Decelea, they created a constant threat near the Athenian heartland. As a result, Athens had to split its forces. Some troops stayed home to guard the city, while others fought abroad. This division strained Athenian strength. Even so, Athens tried to hold its ground. However, the strategy worked in Sparta’s favor. Over time, the growing demands pushed Athens closer to collapse.
Persian Support
Crucially, Sparta received support from the Persian Empire, which provided financial backing for the construction and maintenance of the naval base. The Persians, having their own interests in weakening Athens, were willing to aid Sparta in this endeavor.
Impact on the War
The establishment of the naval base at Decelea had a profound impact on the Peloponnesian War. Athens, burdened by the strain of a two-front war and weakened by supply shortages, faced a challenging situation. The Spartan-Persian alliance had successfully shifted the balance of power.
Conclusion
Sparta’s construction of a naval base at Decelea in 413 BC was a strategic masterstroke during the Peloponnesian War. With Persian support, they effectively disrupted Athenian supply routes, forced Athens into a two-front war, and altered the course of the conflict. This endeavor showcases the intricate strategies and political alliances that shaped ancient Greek warfare.
