Romulus is the legendary founder of the city of Rome. He was a formidable warrior, a successful military leader and a competent ruler who put the nascent Roman state on a strong demographic, political and military footing.
Romulus is given credit for organizing the political institutions of the new Roman state. He established the Senate, an advisory body composed of the heads of the leading families of the state; the Centuriate Assembly representing the Roman body politic, organized along military lines (by centuries); the army consisting of Roman citizens, 3,000 infantry and 300 cavalry. This military force was later doubled to 6,000 infantry and 600 cavalry after the incorporation of Sabines into the state. Romulus also acted as the high priest of the state.
