What was the large group of people that made up Rome?

The large group of people that made up Rome primarily consisted of Romans, who were citizens of the city and its territories, including both patricians (the aristocratic class) and plebeians (the common citizens). Additionally, as Rome expanded its empire, it incorporated diverse groups from various regions, including conquered peoples who became subjects or allies. This diverse population contributed to Rome's cultural, social, and economic life, making it a melting pot of different traditions and practices.
