The present research aims to answer the question: “How did the Persian people, particularly the Achaemenid dynasty, manage to preserve themselves and ensure their survival in history when confronted with the aggressions of the Assyrian Empire, and by what strategies?” The Assyrian state, located in northern Mesopotamia, was one of the most powerful empires of the ancient era. Possessing a formidable army and surrounded by weaker neighbors, it embarked on an extensive expansion of its territory. This state routinely engaged in massacres of populations through attacks on other nations and neighboring states such as Elam, Babylon, Urartu, Media, and Egypt. Furthermore, by plundering resources and conquering defeated nations, Assyria compelled their populations to migrate. One of the peoples who drew Assyria’s attention was the Persian people. They initially settled in the west or southwest of Lake Urmia before migrating south, establishing themselves in proximity to Elam and Media. Following repeated Assyrian aggressions against Elam in the late 8th century BCE, the Persians capitalized on Elam’s weakened state and asserted control over Anshan. Under the leadership of Achaemenes and, notably, his son Teispes, these Pasargadae Persians employed strategies to counter Assyria that ultimately saved them from its attacks. Crucially, without surrendering prisoners or war spoils to Assyria, they safeguarded themselves primarily through three strategies: migration, the payment of tribute, and ultimately, neutrality.
