Romulus was the first king of rome and he was a great king and the people loved him. In 509 B.C a person named Tarquin the proud ruled Rome. The people got sick of him because he ruled unfairly. The people kicked him out and decided to set up a completely different type of government. They made Rome into a republic
( Rome was the first ever republic in history ).
So instead of a king making all the discussions and being in charge, the people would elect people who would serve in the government from a certain amount of time. People were able to do whatever they wanted, as long as it didn’t break the law.
Under this new form of government, Rome was successful.
Rome stayed as a republic until 27 A. D.
