How did Evagoras of Salamis challenge Persian rule in Cyprus?

Evagoras, the king of Salamis, challenged Persian rule by adopting a pro-Hellenic policy and actively expanding his influence across Cyprus and parts of Anatolia. Initially maintaining friendly relations with the Achaemenian Empire, his relationship with Persia deteriorated by 391 BCE, leading to a state of virtual war.12

To sustain his rebellion, Evagoras secured military support from Athens and Egypt, allowing him to extend his authority over much of the island. However, his position weakened significantly after Athens withdrew its support following the Peace of Antalcides in 386 BCE. Without allies, his forces were eventually defeated by the Persians at Citium in 381 BCE. Following this defeat, he was forced to accept a peace agreement that left him as a nominal king of Salamis while effectively serving as a vassal to the Achaemenian monarch until his assassination in 374 BCE.12
