Magna Græcia (Latin meaning "Great Greece", Greek: Μεγάλη Ἑλλάς, Megálē Hellás) is the name of the coastal areas of Southern Italy on the Tarentine Gulf that were extensively colonized by Greek settlers; particularly the Achaean colonies of Tarentum, Crotone, and Sybaris, but also, more loosely, the cities of Cumae and Neapolis to the north. The colonists, who began arriving in the 8th century BC, brought with them their Hellenic civilization, which was to leave a lasting imprint in Italy, particularly on the culture of ancient Rome.
