Cambyses II
The Achaemenid Empire of the Persian king Cyrus the Great conquered the city in 539 B.C. The Persians divided Phoenicia into four vassal kingdoms: Sidon, Tyre, Arwad, and Byblos. They prospered, furnishing fleets for Persian kings. However, when Cambyses II organised a war campaign against Carthage, Tyre refused to sail against its daughter city.
