How many classes were in rome after 750 b. c.?

Ancient Rome was made up of a structure called a social hierarchy, or division of people into differently-ranked groups depending on their jobs and family. The emperor was at the top of this structure, followed by the wealthy landowners, the common people, and the slaves (who were the lowest class).

To answer how many classes, around 4.

Thank you. Please consider brainlisting me- I need just one more to rank.
