Explanation:

After the expulsion of the kings, Rome was ruled by its aristocrats (roughly, the patricians) who abused their privileges. This led to a struggle between the people (plebeians) and the aristocrats that is called the Conflict of the Orders. The term "orders" refers to the patrician and plebeian groups of Roman citizens.

Plebeians were the lower-class, often farmers, in Rome who mostly worked the land owned by the Patricians. ... In 450 BC, plebeians were barred from marrying patricians, but this law was repealed in 445 BC by a Tribune of the Plebs.
