The History of the Constitution of the Roman Kingdom is a study of the ancient Roman Kingdom that traces the progression of Roman political development from the founding of the city of Rome in 753 BC to the overthrow of the Roman Kingdom in 510 BC. The constitution of the Roman Kingdom vested the sovereign power in the King of Rome. The king did have two rudimentary checks on his authority, which took the form of a board of elders (the "Roman Senate") and a popular assembly (the "Curiate Assembly"). The arrangement was similar to the constitutional arrangements found in contemporary Greek city-states (such as Athens or Sparta). These Greek constitutional principles probably came to Rome through the Greek colonies of Magna Graecia in southern Italy. In the centuries before the legendary founding of the city of Rome, Greek settlers had colonized much of the Mediterranean world. These settlers carried Greek ideals with them, and often kept in contact with the Greek mainland. Thus, the superstructure of the Roman constitution was ultimately of Greek origin.
