Polycrates (r. c. 535-522 BCE) was the tyrant of Samos who established Samian naval supremacy in the eastern Aegean and strove for control of the Aegean Sea and mainland towns of Ionia in the 6th century BCE. Polycrates had a successful career until the Persian Oroetus (r. c. 530-520 BCE) lured him to the mainland and had him crucified.
