The Fragile Balance of Power in the Aegean
The year 411 BCE marked a critical juncture in the Peloponnesian War, when the conflict between Athens and Sparta entered its most complex phase. As the war dragged into its twentieth year, both sides found themselves increasingly dependent on foreign support, particularly from the Persian Empire. The strategic island of Rhodes became a focal point when Peloponnesian forces, responding to invitations from Rhodian leaders, sailed with 94 ships to establish control. Their arrival at Camirus shocked the unprepared populace, who fled before being persuaded to join the Spartan alliance. This development sent shockwaves through the Athenian command at Samos, who launched a preemptive but ultimately unsuccessful naval expedition to prevent Rhodes’ defection.
Meanwhile, the Persian satrap Tissaphernes played a dangerous game of balancing Greek factions against each other. His financial support for the Peloponnesian fleet came with strings attached – payments were irregular and often reduced, creating growing resentment among Spartan allies. The Athenians, facing their own financial difficulties, watched these developments with increasing alarm as their imperial revenues dwindled and their naval supremacy faced its most serious challenge since the Sicilian disaster.
Alcibiades and the Persian Gambit
The exiled Athenian general Alcibiades emerged as the most intriguing figure in this complex geopolitical puzzle. After falling out with the Spartans and fearing for his life following their order for his execution, Alcibiades sought refuge with Tissaphernes. His intimate knowledge of Greek politics made him invaluable to the Persian satrap, who employed him as a chief advisor. Alcibiades implemented a shrewd strategy to weaken both Greek powers: he convinced Tissaphernes to reduce payments to the Peloponnesian fleet from one Attic drachma to three obols per day (half the previous rate), arguing this would prevent sailors from becoming corrupted by wealth.
More significantly, Alcibiades advised Tissaphernes to prolong the war by maintaining a balance of power. He warned against allowing either side to gain complete control of both land and sea, suggesting Persia should let the Greeks exhaust themselves through continued conflict. This advice aligned perfectly with Persian interests and demonstrated Alcibiades’ sophisticated understanding of realpolitik. His arguments that Athens made a more suitable imperial partner than Sparta – because Athenian ambitions were primarily maritime rather than territorial – reveal his ability to frame policies in terms that served both his personal interests and those of his Persian patrons.
The Oligarchic Conspiracy in Athens
The situation took a dramatic turn when elements within the Athenian fleet at Samos, recognizing Alcibiades’ influence over Tissaphernes, began plotting to overthrow the democracy. They believed that replacing the democratic government with an oligarchy would facilitate Alcibiades’ return and secure Persian financial support. This conspiracy gained momentum through secret societies (hetairiai) in Athens and the military leadership at Samos. The oligarchic faction, led by figures like Peisander, argued that only through constitutional change could Athens hope to win the war.
Phrynichus, one of the Athenian generals, emerged as the most vocal opponent of this plan. He correctly suspected Alcibiades cared little for oligarchy and was primarily interested in securing his return. In a remarkable act of betrayal, Phrynichus even attempted to warn the Spartan commander Astyochus about Alcibiades’ machinations, demonstrating the lengths to which political factions were willing to go in this crisis. When his warning was leaked, Phrynichus narrowly avoided disaster by fortifying Samos against a potential Spartan attack, turning Alcibiades’ subsequent accusations against him into evidence of his own vigilance.
The Four Hundred Seize Power
Back in Athens, the oligarchic conspirators moved decisively. Through a combination of political maneuvering and intimidation, they established a new constitution that concentrated power in the hands of four hundred oligarchs. The assembly, under pressure at the temple of Poseidon at Colonus, voted away its own democratic institutions under the pretense of establishing a broader government of five thousand (though this larger body never actually convened). The coup was supported by armed contingents from Andros, Tenos, and other allied cities, ensuring its success through the threat of violence.
The new regime immediately sought peace with Sparta, sending envoys to King Agis at Decelea. However, Agis remained skeptical of their stability and launched a probing attack against Athens’ walls. When this failed to provoke the expected internal collapse, he withdrew, leaving the oligarchs to consolidate their position. Meanwhile, they dispatched representatives to Samos to justify their actions to the fleet, claiming the changes were necessary to save Athens and that real power rested with the five thousand, not just the four hundred.
Democratic Resistance at Samos
The situation at Samos took an unexpected turn when the Athenian forces there, learning of the oligarchic coup, revolted against the new regime. The democratic faction, supported by the crew of the state trireme Paralus, gained the upper hand after violent clashes with oligarchic sympathizers. In a remarkable display of political independence, the Samos-based Athenians established what amounted to a democratic government-in-exile, electing new generals like Thrasybulus and Thrasyllus who were committed to restoring democracy.
This rebel government made several bold claims: that they represented the true Athenian state, that they could finance themselves through the empire without support from the oligarchic regime, and that they might even recall Alcibiades to secure Persian support. Their position was strengthened when they successfully defended against a Peloponnesian naval attack, proving their military capability independent of Athens. The stage was set for a civil war within the Athenian state itself, with democratic forces at Samos pitted against the oligarchic government in Athens.
Strategic Stalemate and the Failure of Alcibiades’ Plan
As these political dramas unfolded, the military situation reached a stalemate. The Peloponnesian fleet, frustrated by Tissaphernes’ continued delays and reduced payments, grew increasingly restless. The Syracusan contingent in particular pressed for immediate action against the Athenians. When they finally sailed to challenge the Athenian fleet at Samos, both sides hesitated to engage in a decisive battle, the Athenians waiting for reinforcements from the Hellespont and the Peloponnesians ultimately withdrawing to Miletus when those reinforcements arrived.
Alcibiades’ intricate scheme ultimately failed to achieve its primary objectives. His negotiations with Athenian envoys collapsed when he made impossible demands (including allowing Persian ships to sail freely in Athenian waters), exposing the limits of his influence with Tissaphernes. The satrap, still wary of Spartan ambitions in Asia Minor, eventually renewed his treaty with the Peloponnesians but continued to withhold full support, maintaining the balance of power Alcibiades had recommended.
Legacy of the 411 BCE Crisis
The events of 411 BCE represented one of the most complex political-military crises of the Peloponnesian War. They demonstrated how external pressures could fundamentally transform a city’s political institutions, as Athens’ democracy gave way (however temporarily) to oligarchy under the strain of prolonged warfare. The simultaneous existence of two Athenian governments – the oligarchic regime in Athens and the democratic faction at Samos – created a unique constitutional crisis that foreshadowed later divisions in Greek political life.
Alcibiades’ role as a political chameleon reached its zenith during this period, as he navigated between Spartan, Persian, and Athenian interests with remarkable dexterity. His failure to deliver Persian support to either side, however, revealed the limits of personal diplomacy in the face of structural geopolitical realities. The eventual collapse of the Four Hundred oligarchy several months later would pave the way for his return to Athenian politics, but the events of 411 permanently altered the political landscape of the Athenian empire.
Most significantly, these events demonstrated how the pressures of total war could unravel even the most established political systems. The democratic ideals that had defined Athens for nearly a century proved vulnerable when survival seemed to require their abandonment. Yet the fierce resistance of the Samos-based fleet also showed the enduring appeal of those ideals, even among those who had every reason to resent the democracy that had exiled Alcibiades and failed to prevent the Sicilian disaster. This tension between pragmatism and principle would continue to shape Athenian politics until the war’s bitter conclusion seven years later.
