Dion (/ˈdaɪɒn, ən/; Greek: Δίων ὁ Συρακόσιος; 408–354 BC), tyrant of Syracuse in Magna Graecia, was the son of Hipparinus, and brother-in-law of Dionysius I of Syracuse. A disciple of Plato, he became Dionysius I's most trusted minister and adviser. However, his great wealth, his belief in Platonism and his ambition aroused the suspicions of Dionysius I's son and successor, Dionysius II. An indiscreet letter from Dion to the Carthaginians led to his banishment. Settling in Athens, he lived a prosperous life until Dionysius II dispossessed him of his estates and income. Landing in Sicily in 357 BC, he was successful in conquering Syracuse (other than the citadel). However, Dion soon quarrelled with the radical leader Heraclides and was forced into exile. Recalled in 355 BC, he became master of the whole city but alienated the population with his imperious behaviour and financial demands. His supporters abandoned him, and he was assassinated. Dion's attempts to liberate Sicily only brought the island political and social chaos which lasted for nearly 20 years.
