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.
Direct democracy
Also relevant to the history of direct democracy is the history of Ancient Rome, specifically the Roman Republic, beginning around 509 BC. Rome displayed many aspects of democracy, both direct and indirect, from the era of Roman monarchy all the way to the collapse of the Roman Empire. Indeed, the Senate, formed in the first days of the city, lasted through the Kingdom, Republic, and Empire, and even continued after the decline of Western Rome; and its structure and regulations continue to influence legislative bodies worldwide. As to direct democracy, the ancient Roman Republic had a system of citizen lawmaking, or citizen formulation and passage of law, and a citizen veto of legislature-made law. Many historians mark the end of the Republic with the passage of a law named the "Lex Titia", 27 November 43 BC, which eliminated many oversight provisions.
