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.

Beginning with Caesar's assassination in 44 BC and ending with Octavian's victory over Anthony and Cleopatra at Actium in 31 BC, Rome had been engaged in a series of almost constant civil wars. After almost 15 years of political and social upheaval, Octavian, the sole surviving member of the Second Triumvirate, became firmly established as the new leader of the Roman world. Under Octavian, Rome enjoyed a long period of relative peace and prosperity. However, Octavian's victory at Actium also sounded the death knell of the Republic. With Octavian as the sole ruler of the Roman world, the Roman Empire was born.
