History of the Constitution of the Roman Republic
The history of the Constitution of the Roman Republic is a study of the ancient Roman Republic that traces the progression of Roman political development from the founding of the Roman Republic in 509 BC until the founding of the Roman Empire in 27 BC. The constitutional history of the Roman Republic can be divided into five phases. The first phase began with the revolution which overthrew the Roman Kingdom in 509 BC, and the final phase ended with the revolution which overthrew the Roman Republic, and thus created the Roman Empire, in 27 BC. Throughout the history of the republic, the constitutional evolution was driven by the struggle between the aristocracy and the ordinary citizens.
Italy
Rome, a settlement around a ford on the river Tiber conventionally founded in 753 BC, was ruled for a period of 244 years by a monarchical system, initially with sovereigns of Latin and Sabine origin, later by Etruscan kings. The tradition handed down seven kings: Romulus, Numa Pompilius, Tullus Hostilius, Ancus Marcius, Tarquinius Priscus, Servius Tullius and Tarquinius Superbus. In 509 BC, the Romans expelled the last king from their city and established an oligarchic republic.
