The colonies established by Greek poleis (city-states) in the Hellenic era included a number along the coast of southern Italy and Sicily, an area already populated by a variety of different groups that farmed, fished, and traded. So many Greek settlers came to this area that it later became known as Magna Graecia — Greater Greece. Although Alexander the Great created an empire that stretched from his homeland of Macedonia to India, his conquests did not reach as far as southern Italy and Sicily. Thus the Greek colonies there remained independent, and they transmitted much of their culture to people who lived farther north in the Italian peninsula. These included the Etruscans (ih-TRUHS-kuhns), who built the first cities north of Magna Graecia, and then the Romans, who eventually came to dominate the peninsula. In addition to allying with conquered peoples and granting them citizenship, the Romans established a republic ruled by a Senate. However, social conflicts over the rights to power eventually erupted and had to be resolved.
