Who were the two main opponents in the peloponnesian war? a: sparta and athens b: syracuse and corinth c: greece and persia d: ionia and thessaly

The correct answer is A) Sparta and Athens. The war is often thought of in three phases: the first phase where Sparta launched repeated attacks on Attica, while Athens raided the Peloponnesian coast, the second phase was when Athens sent a massive force to Syracuse in Sicily and the third phase is when Sparta gained support from Persia and supported the rebellions in Athens, that the city-state had been trying to suppress. This eventually undermined Athens naval supremacy and ability.
