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 conquest of the Iberian peninsula
The Roman conquest of the Iberian peninsula was a process by which the Roman Republic seized territories in the Iberian peninsula that were previously under the control of native Celtiberian tribes and the Carthaginian Empire. The Carthaginian territories in the south and east of the peninsula were conquered in 206 BC during the Second Punic War. Control was gradually extended over most of the Iberian peninsula without annexations. It was completed after the fall of the Republic (27 BC), by Augustus, the first Roman emperor, who annexed the whole of the peninsula to the Roman Empire in 19 BC. The peninsula had various ethnic groups and a large number of tribes.
