Dionysius I and the Rise of Syracuse
Sicily's Greek cities had faced periodic Carthaginian invasions since Carthage's Phoenician colonies on the island's western edge came into conflict with Greek expansion. A renewed Carthaginian invasion in 406-405 BCE captured several Greek cities and besieged Syracuse itself, creating exactly the crisis atmosphere in which the young cavalry officer Dionysius exploited popular fear to have himself voted emergency military powers -- and then never relinquished them, ruling as tyrant until his death in 367 BCE. Dionysius transformed Syracuse into a fortress state: he built the massive Euryalus fortress and walls enclosing an unprecedented urban area, assembled a fleet larger than any Greek navy since Athens's fifth-century peak, and pioneered new siege engines including the catapult, first attested in Dionysius's arsenal during his wars against Carthage. He fought Carthage to a series of negotiated settlements that left Carthage controlling western Sicily but Syracuse dominant over the Greek cities of the east and much of Magna Graecia in southern Italy. His court became a magnet for Greek intellectuals -- Plato visited (twice, disastrously, nearly being sold into slavery after offending Dionysius) -- and Syracuse under Dionysius briefly rivalled Athens and Sparta as a centre of Greek political and cultural life, though his rule also established the tyrant-dynasty pattern (his son Dionysius II succeeded him) that later Greek political theory, including Plato's, would treat as democracy's cautionary opposite.
