아테네인들은 결국 승리하였지만 시보타의 전투는 펠레폰네소스 전쟁으로 이어졌다. 그것은 결국 아테네의 헤게모니를 파괴하였다.
기원전 431년 [[아테네]]는 [[트라키아]]의 왕 시탈케스왕과 동맹하였다.
In 431, Athens entered into an alliance with King [[Sitalkes]] of [[Thrace]], after Nymphodorus, an Athenian, married Sitalkes’ sister. Nymphodorus then negotiated an agreement between Athens and Perdiccas, where Perdiccas regained Therme. As a result of this, Athens withdrew her support for Philip, and the Thracians promised to assist Perdiccas in capturing him. In return, Perdiccas marched on the Chalcidians, the people he had originally persuaded to revolt.
However, Perdiccas once again betrayed the Athenians and sent 1000 troops to support a Spartan assault on Acarnania in 429 but they arrived too late to help (Thucydides 2.80). In response to this, Sitalkes invaded Macedonia with the promise of support from Athens. This support never materialized, and Perdiccas once again used diplomacy to ensure the survival of Macedonia. He promised the hand of his sister in marriage to the nephew of Sitalkes, who then persuaded Sitalkes to leave.
After this, Perdiccas was allied to the [[Sparta|Spartans]] and, in 424, helped the Spartan [[Brasidas]] to take Amphipolis from the Athenians, one of her most important colonies, mainly for its ready access to timber for her fleets. This was a severe blow to Athens, and would tie them to Macedonian timber for years to come, which strengthened Macedonia’s bargaining power considerably. In return for this, the Spartans helped Perdiccas secure his borders, by leading an assault on King Arrhabaeus of Lyncus, with the promise of support from the [[Illyrians]]. However, the Illyrians switched sides and attacked Perdiccas and his Spartan allies. The poorly trained Macedonian troops fled, and so the Spartans also retreated and attacked the Macedonian baggage train in anger. This soured relations between Macedonia and the Peloponnese for years to come, and pushed Perdiccas closer to Athens, allying himself with them in 423.
