QUOTE : Rome became a republic in 509 B.C., after driving out its king and abolishing the monarchy. The next two centuries saw a long struggle for power between a group of noble families, patricians, and ordinary citizens, plebeians, who were excluded from public office. The outcome was a apparent victory for the people, but the old aristocracy, supplemented by rich pledeian nobles, still controlled the state. What looked in many ways like democracy was, in fact, an oligarcy modified by elections.
