Final answer:
The three levels of society in the Campania region were patricians, equites, plebeians, and slaves. Individuals could potentially move between social classes, but upward mobility was limited.
Step-by-step explanation:
Roman society in the Campania region had three levels: patricians, equites, plebeians, and slaves. Patricians were the upper class and held the most power and wealth. Equites were the middle class, consisting of knights and some wealthy businessmen. Plebeians were the common people, who made up the majority of the population. Slaves were at the bottom of the social hierarchy and had no rights or freedom.
While these social classes were generally fixed, there was some possibility for individuals to move between classes. For example, some plebeians could attain higher positions in society through military service, business success, or marriage into higher-class families. Similarly, some equites could become patricians if they amassed enough wealth and influence. However, upward mobility was limited, and the majority of Romans remained within their social class throughout their lives.
