    Sparta and Athens had an uneasy rivalry leading up to the Peloponnesian War.

    To understand how neighbors could turn against neighbors in a decades-long war, we first need to understand a bit of history between Athens and Sparta.

    The Peloponnesian War started around 431 BC. Less than 30 years had passed since the end of the Persian Wars, which had seen Athens and Sparta united against Persia in a war that lasted around 50 years. Since then, Athens and Sparta had each enjoyed a period of relative peace.

    Athens flourished and created a maritime empire. It controlled the Delian League, an alliance of 150 city-states, situated largely around the Aegean Sea. The alliance maintained a steady trade of food, supplies, and material. But this success didn’t sit well with Sparta, which headed its own alliance of city-states, known as the Peloponnesian League.

    The key message here is: Sparta and Athens had an uneasy rivalry leading up to the Peloponnesian War.

    While Athens had a functioning democracy, Spartan politics was something of a mixed bag, with democratic, oligarchic, and monarchic mixed together. Sparta had two kings, but they also had elected magistrates known as ephors, and an assembly of men over 30 who voted on foreign and domestic policy. But voting only took place when the Spartan elites called for it.

    Another major difference between Athens and Sparta was their societal structure. In Athens, all citizens were considered equal, but Sparta had a strict hierarchy with two different types of subordinate people: helots and perioikoi. Helots were a step above slaves and were responsible for farming. The perioikoi were responsible for manufacturing and trade.

    Above all, Sparta was focused on its legendary military. And due to the helots and the perioikoi, the Spartans themselves were free to train for battle. But since the helots outnumbered Spartans around seven to one, there was always the threat of a helot uprising, especially when the army was on a military campaign. So, Sparta wasn’t exactly eager to engage in any massive, prolonged wars.

    And neither was Athens, for that matter. Nonetheless, there were serious concerns in Sparta that Athens and the Delian League were becoming too powerful – that Athens’s imperial ambitions had gotten out of hand. In 431 BC, this feeling would reach its tipping point.
