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.
Roman Kingdom
Brutus and Collatinus became Rome's first consuls, marking the beginning of the Roman Republic. This new government would survive for the next 500 years until the rise of Julius Caesar and Caesar Augustus, and would cover a period during which Rome's authority and area of control extended to cover great areas of Europe, North Africa, and the Middle East.
