Magna Graecia

Magna Graecia was the historical Greek-speaking area of southern Italy. It encompassed the modern Italian regions of Calabria, Apulia, Basilicata, Campania, and Sicily. These regions were extensively settled by Greeks beginning in the 8th century BC.

Initially founded by their metropoleis (mother cities), the settlements evolved into independent and powerful Greek city-states (poleis). The settlers brought with them Hellenic civilization, which over time developed distinct local forms due to both their distance from Greece and the influence of the indigenous peoples of southern Italy. This interaction left a lasting imprint on Italy, including on Roman culture. The Greek settlers also influenced native groups such as the Sicels and the Oenotrians, many of whom adopted Greek culture and became Hellenized. In areas like architecture and urban planning, the colonies sometimes surpassed the achievements of the motherland. The ancient inhabitants of Magna Graecia are referred to as Italiotes and Siceliotes.

Ruins of several cities from Magna Graecia remain visible today, including Neàpolis ("New City", now Naples), Syrakousai (Syracuse), Akragas (Agrigento), Taras (Taranto), Rhegion (Reggio Calabria), and Kroton (Crotone). The most populous city was Sybaris (now Sibari), with an estimated population of between 300,000 and 500,000, from 600 to 510 BC.

Governments in these city-states were typically aristocratic, and the cities often engaged in warfare with one another.
