Intro to Ancient Greece Unit 8 ReviewThe Peloponnesian War's Impact

Key Events and Timeline

• The Peloponnesian War lasted from 431 BC to 404 BC, a period of 27 years
• Divided into three distinct phases: the Archidamian War (431-421 BC), the Peace of Nicias (421-415 BC), and the Decelean War (415-404 BC)
• The Archidamian War began with Sparta's invasion of Attica and ended with the Peace of Nicias
• The Peace of Nicias was a truce that lasted for six years, although hostilities continued indirectly
• The Decelean War, named after the Spartan fort of Decelea in Attica, marked the final phase of the conflict
• Athens' disastrous Sicilian Expedition (415-413 BC) during the Decelean War significantly weakened its power
• The war concluded in 404 BC with the surrender of Athens and the end of its naval empire

Major Participants and Alliances

• The two main belligerents were Athens and its Delian League allies against Sparta and the Peloponnesian League
• Athens, a naval power, relied on its strong fleet and wealth from the Delian League
• Sparta, a land-based military power, boasted a formidable army and alliances with other city-states
• Key Athenian figures included Pericles, Cleon, Nicias, Alcibiades, and Demosthenes
• Notable Spartan leaders were Archidamus II, Brasidas, Lysander, and Agis II
• Other important city-states involved were Corinth and Thebes (allied with Sparta) and Argos (allied with Athens)
• The Persians, under Darius II, later intervened on the side of Sparta, providing financial support

Causes and Triggers

• Long-standing tensions between Athens and Sparta, fueled by their divergent political systems and ideologies (democracy vs. oligarchy)
• Athens' growing power and influence through the Delian League, which Sparta perceived as a threat to its hegemony
• The Megarian Decree, imposed by Athens, which economically crippled Sparta's ally Megara and heightened tensions
• Conflicts between Athens and Corinth, particularly over Corcyra and Potidaea, which drew Sparta into the war
• Sparta's fear of Athens' expansionist policies and its potential to dominate the Greek world
• The debate in Sparta's assembly, where the majority voted for war against Athens
• Pericles' aggressive stance and refusal to make concessions to Sparta's demands

Strategies and Tactics

• Athens relied on its naval superiority, using its fleet to protect its empire and harass Spartan allies
• Pericles' defensive strategy involved withdrawing the population within Athens' walls and avoiding land battles
• Sparta focused on land-based warfare, invading Attica annually to destroy crops and infrastructure
• Sparta sought to undermine Athens' power by encouraging revolts among its allied city-states
• Athens employed a counter-strategy of raiding the Peloponnesian coast and supporting Sparta's enemies
• Both sides engaged in diplomacy and propaganda to gain allies and weaken their opponent's support
• Athenian generals, such as Demosthenes, conducted ambitious amphibious operations to attack Spartan territories
• Sparta adapted its strategy by establishing a permanent fort at Decelea in Attica, disrupting Athens' supply lines

Significant Battles and Campaigns

• The Plague of Athens (430-426 BC) devastated the city's population and morale, claiming the life of Pericles
• The Mytilenean Debate (427 BC) showcased Athenian ruthlessness in suppressing a revolt by the city of Mytilene
• The Battle of Pylos (425 BC) resulted in a major Athenian victory and the capture of Spartan hoplites on the island of Sphacteria
• The Sicilian Expedition (415-413 BC), a turning point in the war, ended in a disastrous defeat for Athens
  • Athens sought to conquer Syracuse, a powerful city-state in Sicily, but suffered heavy losses and a significant blow to its prestige
• The Battle of Aegospotami (405 BC) saw the destruction of the Athenian fleet by Lysander, paving the way for Sparta's final victory

Social and Economic Consequences

• The war led to significant loss of life, both through battle and the Plague of Athens
• Economic disruption and devastation, particularly in Attica, due to repeated Spartan invasions and the occupation of Decelea
• Increased poverty and social unrest in Athens as a result of the war's hardships
• Decline in Athenian cultural and intellectual life, as resources were diverted to the war effort
• Strained relations between Athens and its allies, many of whom sought to break away from Athenian control
• The weakening of the Greek city-states overall, leaving them vulnerable to future external threats
• The rise of mercenaries and professional soldiers, as the war created a demand for their services

Political Aftermath

• The defeat of Athens and the dismantling of its empire, which had far-reaching consequences for the Greek world
• The establishment of a Spartan hegemony, as Sparta became the dominant power in Greece
• The installation of pro-Spartan oligarchies in Athens and other defeated city-states
• The weakening of the democratic system in Athens and the brief rule of the Thirty Tyrants (404-403 BC)
• The restoration of democracy in Athens under Thrasybulus and the amnesty for past actions during the war
• The continued instability and conflict among Greek city-states, setting the stage for future wars and alliances
• The emergence of new powers, such as Thebes and later Macedon, which would challenge Spartan dominance

Long-term Historical Impact
