What were the causes of the Peloponnesian war
The Peloponnesian War was a conflict between the city-states of Athens and Sparta that took place from 431 to 404 BCE. Several factors contributed to the outbreak of the war:
1. Rivalry between Athens and Sparta: Athens, a major power in Greece, had grown into a dominant maritime empire, while Sparta, a military powerhouse, was the leader of the Peloponnesian League. The two city-states had conflicting interests and ambitions, leading to growing tensions.
2. Megarian Decree: Athens passed a trade decree known as the Megarian Decree in 432 BCE, which excluded Megara, an ally of Sparta, from trading with Athens and its empire. This economic blockade angered Sparta and its allies, who saw it as an aggressive move by Athens.
3. Delian League and Peloponnesian League: Athens had formed the Delian League, an alliance of various city-states, to protect against Persian invasions. Over time, Athens transformed the league into its own empire, which led to growing distrust and resentment from other Greek city-states, particularly Sparta and its allies in the Peloponnesian League.
4. Corinth's grievances: Corinth, a major Spartan ally, was a significant power in Greece. The city-state had various grievances with Athens, including naval aggression and interference in Corinth's trade interests. Corinth's complaints were used as a pretext for Sparta to go to war against Athens.
5. Sicilian Expedition: Athens decided to invade Sicily, a territory held by the city-state of Syracuse, in 415 BCE. This ambitious expedition, which ultimately failed, provoked a backlash and generated feelings of betrayal among Athens's allies. Sparta saw this as an opportunity to weaken Athens further.
6. Fear of Athens's power: Athens's growing imperialism, economic dominance, and democratic regime caused fear among other city-states, particularly Sparta and its allies. They perceived Athens as a threat to their own interests and the traditional Greek way of life.
These factors, among others, converged and led to the outbreak of the Peloponnesian War, causing significant devastation and fundamentally reshaping the political landscape of ancient Greece.
