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.
History of democracy
The Roman Empire was eventually divided between the Western Roman Empire which fell in 476 AD and the Eastern Roman Empire (also called the Byzantine Empire) which lasted until the fall of Constantinople in 1453 AD.Most of the procedures used by modern democracies are very old. Almost all cultures have at some time had their new leaders approved, or at least accepted, by the people; and have changed the laws only after consultation with the assembly of the people or their leaders. Such institutions existed since before the times of the "Iliad" or of the "Odyssey", and modern democracies are often derived from or inspired by them, or what remained of them.
