Who were the Roman people made of? Who could participate in the government?

The emperor was at the head of the government.

Next came the senators. These were the richest representatives of the Roman people who sat in the Senate. This meeting drafted laws, discussed taxes and foreign policy. Often the emperor was elected from this class.

The next estate is the horsemen. Their fortune was less than that of the senators. They were generally not allowed to attend the Senate meetings, but sometimes they could influence the state life of Rome.

And finally, there were the plebeians. They had the rights of Roman citizenship. They were engaged in various activities: agriculture, trade, crafts. From among them, elected representatives were elected, who communicated with representatives of the ruling class.
