Kingship Investigates White People Gov't 509 B.C. Coup Roman Republic Name.

Romulus

Romulus, son of the god of war and the daughter of the king Numitor, was the first king of Rome and also its founder, thus the city was called after him. He formed the Roman Senate with one hundred men and gave the inhabitants of Rome a body of laws

Chapter 5, page 152, "The Roman State." The Romans had been ruled by kings under the Etruscans. As a result, they distrusted kingship and devised a very different system of government. 

According to  history, the first king of Rome was Romulus, who founded the city in 753 BC upon the Palatine Hill. Seven legendary kings are said to have ruled Rome until 509 BC, when the last king was overthrown. These kings ruled for an average of 35 years

The overthrow of the Roman King, a political revolution in ancient Rome, took place around 509 BC and resulted in the expulsion of the last king of Rome, Lucius Tarquinius Superbus, and the establishment of the Roman Republic. ... The Roman army supported Brutus, and the king went into exile

The Roman Empire was founded when Augustus Caesar proclaimed himself the first emperor of Rome in 31BC and came to an end with the fall of Constantinople in 1453 CE. An empire is a political system in which a group of people are ruled by a single individual, an emperor or empress.
