Thucydides cited the Thasian episode as one of the incidents during the pentecontaetia which marked the transformation of the Delian League into an Athenian empire. Modern scholars have also approached it as a telling indicator of the internal politics of Sparta, revealing the presence of a strong war party there during a time of peace and harmony between Athens and Sparta and foreshadowing the breakdown of relations which would result in the outbreak of the First Peloponnesian War by the end of the decade.
