What are the consequences of the refusal of the plebeians to participate in military campaigns and the departure from Rome in V BC?

The plebeians received the right to participate in the government.
It is known that throughout the history of Rome, the Senate consisted of two governing branches – the Plebeians and the Patricia. Where the Plebeians represented the interests of ordinary citizens, and the Patricians, in turn, defended the interests of the upper strata of the population.
