How did ancient Rome's government develop?

Answer 1

The development of Rome started with the creation of the Roman state. According the semi-legendary story of the foundation of Rome, Romulus was its founder. He became the ruler of the Palatine Hill, the central hill of the Seven Hills of Rome. He then united the people of the settlements on the other hills into a single state and became the first king of Rome. Archaeological evidence shows that he built a regia (royal palace) and several temples in the forum, an area in a valley between three of the hills. He turned the forum into the civic centre of the newly founded city-state. The temples were places of worship for the people of all the settlements and the gods they were dedicated to became gods of all the Romans.

Romulus also created a royal advisory body, called the senate. This was a council of elders (senate comes from senex, which means old man). He selected 100 pater familias (head of the family/ head of the household) from the leading clans of Rome at the time to sit in the senate. This assured participation and consensus to his rule by the rich and powerful. He also divided Rome into three districts. Each district supplied 1,000 infantrymen and 100 cavalrymen to create an army of 3,000 soldiers and 300 cavalry. Rome was also divided into 30 curiae and the Assembly of the Curiae (Assembly of the Constituencies) was developed. The curiae voted separately and the vote of each curia counted for one vote. The vote was determined by the majority of the votes of the curiae.
