The Megarian Decree, enacted during the Peloponnesian War in the 5th century BCE, was a significant economic sanction imposed by Athens on the city-state of Megara. This punitive measure had far-reaching consequences for both Athens and Megara.
Background
The decree was a product of the ongoing Peloponnesian War between Athens and its Delian League allies and the Peloponnesian League, led by Sparta. Megara, located strategically between Athens and Corinth, had shifted its allegiance from Athens to Sparta, which angered the Athenians.
The Content of the Megarian Decree
The Megarian Decree forbade Megarians from engaging in trade and commerce within the Athenian Empire, which included the vital Black Sea ports. This measure crippled Megara’s economy, as trade was a lifeline for the city.
Pericles’ Role
Pericles, the influential Athenian statesman, championed the decree as a means to weaken Megara and pressure other city-states in the Peloponnesian League. This strategy aimed to isolate Sparta and her allies.
Economic Impact on Megara
The economic consequences for Megara were dire. The city’s trade routes and markets were effectively cut off, causing economic hardship, unemployment, and poverty among its citizens.
Political Implications
The Megarian Decree heightened tensions between Athens and its rivals, particularly Corinth, which was a close ally of Megara. It further polarized the Greek city-states and contributed to the escalation of the Peloponnesian War.
Legal Controversy
The Megarian Decree faced criticism on legal grounds. Critics argued that it violated the Thirty Years’ Truce, a peace treaty between Athens and Sparta. However, Athens maintained that Megara’s actions justified the sanctions.
Long-Term Impact
While the Megarian Decree dealt a significant blow to Megara in the short term, it did not achieve Athens’ ultimate goals in the Peloponnesian War. The conflict continued for nearly three decades, with Athens suffering eventual defeat.
Conclusion
The Megarian Decree was a noteworthy episode in the Peloponnesian War, demonstrating the complex web of alliances, sanctions, and strategies that defined the conflict. It illustrated the lengths to which city-states were willing to go to gain an advantage in this protracted and devastating war.
