The Roman Kingdom, also known as the Roman monarchy and the regal period of ancient Rome, was the earliest period of Roman history, when the city and its territory were ruled by kings. According to tradition, the Roman Kingdom began with the city's founding c. 753 BC, with settlements around the Palatine Hill along the river Tiber in central Italy, and ended with the overthrow of the kings and the establishment of the Roman Republic c. 509 BC.
Little is certain about the kingdom's history as no records and few inscriptions from the time of the kings have survived. The accounts of this period written during the Republic and the Empire are thought largely to be based on oral tradition and debated as to their historicity.
Origin
The site of the founding of the Roman Kingdom (and eventual Republic and Empire) included a ford where one could cross the river Tiber in central Italy. The Palatine Hill and hills surrounding it provided easily defensible positions in the wide fertile plain surrounding them. Each of these features contributed to the success of the city.
The traditional version of Roman history, which has come down principally through Livy (59 BC – AD 17), Plutarch (before 50 – after AD 120), and Dionysius of Halicarnassus (c. 60 BC – after 7 BC), recounts that a series of seven kings ruled the settlement in Rome's first centuries. The traditional chronology, as codified by Varro (116 – 27 BC) and Fabius Pictor (c. 270 – c. 200 BC), allows 243 years for their combined reigns, an average of almost 35 years. Since the work of Barthold Georg Niebuhr, modern scholarship has generally discounted this schema. The Gauls destroyed many of Rome's historical records when they sacked the city after the Battle of the Allia in 390 BC (according to Varro; according to Polybius, the battle occurred in 387 or 386), and what remained eventually fell prey to time or to theft. With no contemporary records of the kingdom surviving, all accounts of the Roman kings must be carefully questioned.
Monarchy
The kings following Romulus, the city's founder, were elected by the people of Rome to serve for life, and did not rely upon military force to gain or keep the throne. The only king to break fully with this tradition was Lucius Tarquinius Superbus, the final king, who according to tradition seized power from his predecessor and ruled as a tyrant.
In reality, most kings of Rome seem to have been leaders of armed bands who through persuasion or force acquired the support of the Roman aristocracy. The kings were not necessarily of Roman or Latin origin. Arnaldo Momigliano writes, "There was probably only a thin dividing line between the band chief called in to help an existing rex [king] and a band chief called in to replace him and therefore to rule in his stead."
The insignia of the kings of Rome were twelve lictors (attendants or servants) wielding the symbolic fasces bearing axes, the right to sit upon a curule seat, the purple toga picta, red shoes, and a white diadem around the head. Of all these insignia, the most important was the purple toga picta.
Chief Executive
The king was invested with supreme military, executive, and judicial authority through the use of imperium, formally granted to the king by the Curiate Assembly with the passing of the Lex curiata de imperio at the beginning of each king's reign. The imperium of the king was held for life and protected him from ever being brought to trial for his actions. As the king was the sole owner of imperium in Rome at the time, he possessed ultimate executive power and unchecked military authority as the commander-in-chief of all of the Roman legions. Also, the laws that kept citizens safe from magistrates' misuse of imperium did not exist during the monarchical period.
The king had the power to either appoint or nominate all officials to offices. He would appoint a tribunus celerum to serve as both the tribune of the Ramnes tribe in Rome and as the commander of the king's personal bodyguard, the celeres. The king was required to appoint the tribune upon entering office and the tribune left office upon the king's death. The tribune was second in rank to the king and also possessed the power to convene the Curiate Assembly and lay legislation before it.
Another officer appointed by the king was the praefectus urbi, who acted as the warden of the city. When the king was absent from the city, the prefect held all of the king's powers and abilities, even to the point of being bestowed with imperium while inside the city.
The king also received the right to be the only person to appoint patricians to the Senate.
Chief Priest
What is known for certain is that the king alone possessed the right to the augury on behalf of Rome as its chief augur, and no public business could be performed without the will of the gods made known through auspices. The people knew the king as a mediator between them and the gods (cf. Latin pontifex, "bridge-builder", in this sense, between men and the gods) and thus viewed the king with religious awe. This made the king the head of the national religion and its chief executive. Having the power to control the Roman calendar, he conducted all religious ceremonies and appointed lower religious offices and officers. It is said that Romulus himself instituted the augurs and was believed to have been the best augur of all. Likewise, King Numa Pompilius instituted the pontiffs and through them developed the foundations of the religious dogma of Rome.
Chief Legislator
Under the kings, the Senate and Curiate Assembly had very little power and authority. They were not independent since they lacked the right to meet together and discuss questions of state at their own will. They could be called together only by the king (and the tribune in the case of the Curiate Assembly) and could discuss only the matters that the king laid before them. While the Curiate Assembly had the power to pass laws that had been submitted by the king, the Senate was effectively an honorary council. It could advise the king on his action but by no means could prevent him from acting. The only thing that the king could not do without the approval of the Senate and the Curiate Assembly was to declare war against a foreign nation.
Chief Judge
The king's imperium both granted him military powers and qualified him to pronounce legal judgement in all cases as the chief justice of Rome. Though he could assign pontiffs to act as minor judges in some cases, he had supreme authority in all cases brought before him, both civil and criminal. This made the king supreme in times of both war and peace. While some writers believed there was no appeal from the king's decisions, others believed that a proposal for appeal could be brought before the king by any patrician during a meeting of the Curiate Assembly.
To assist the king, a council advised him during all trials, but this council had no power to control his decisions. Also, two criminal detectives (quaestores parricidi) were appointed by him as well as a two-man criminal court (duumviri perduellionis), which oversaw cases of treason. According to Livy, Lucius Tarquinius Superbus, the seventh and final king of Rome, judged capital criminal cases without the advice of counsellors, thereby creating fear amongst those who might think to oppose him.
Election of the kings
Whenever a king died, Rome entered a period of interregnum. Supreme power of the state would devolve to the Senate, which was responsible for finding a new king. The Senate would assemble and appoint one of its own members—the interrex—to serve for a period of five days with the sole purpose of nominating the next king of Rome. If no king were nominated at the end of five days, with the Senate's consent the interrex would appoint another Senator to succeed him for another five-day term. This process would continue until a new king was elected. Once the interrex found a suitable nominee to the kingship, he would bring the nominee before the Senate and the Curiate would review him. If the Senate passed the nominee, the interrex would convene the Curiate Assembly and preside over it during the election of the king. Once the nominee was proposed to the Curiate Assembly, the citizens of Rome could either accept or reject him. If accepted, the king-elect did not immediately enter office. Two other acts still had to take place before he was invested with the full regal authority and power.
First, it was necessary to obtain the divine will of the gods respecting his appointment by means of the auspices, since the king would serve as high priest of Rome. This ceremony was performed by an augur, who conducted the king-elect to the citadel, where he was placed on a stone seat as the people waited below. If found worthy of the kingship, the augur announced that the gods had given favourable tokens, thus confirming the king's priestly character. The second act which had to be performed was the conferral of the imperium upon the king. The Curiate Assembly's previous vote only determined who was to be king, and had not by that act bestowed the necessary power of the king upon him. Accordingly, the king himself proposed to the Curiate Assembly a law granting him imperium, and the Curiate Assembly by voting in favor of the law would grant it. In theory, the people of Rome elected their leader, but the Senate had most of the control over the process.
Senate
According to legend, Romulus established the Senate after he founded Rome by personally selecting the most noble men (wealthy men with legitimate wives and children) to serve as a council for the city. As such, the Senate was the King's advisory council as the Council of State. The Senate was composed of three hundred senators, with a hundred senators representing each of the three ancient tribes of Rome: the Ramnes, Tities, and Luceres. Within each tribe, a senator was selected from each of the tribe's ten curiae. The king had the sole authority to appoint the senators, but this selection was done in accordance with ancient custom.
Under the monarchy, the Senate possessed very little power and authority as the king held most of the political power of the state and could exercise those powers without the Senate's consent. The chief function of the Senate was to serve as the king's council and be his legislative coordinator. Once legislation proposed by the king passed the Curiate Assembly, the Senate could either veto it or accept it as law. The king was, by custom, to seek the advice of the Senate on major issues. However, it was left to him to decide what issues, if any, were brought before them and he was free to accept or reject their advice as he saw fit. Only the king possessed the power to convene the Senate, except during the interregnum, during which the Senate possessed the authority to convene itself.
Kings of Rome
Romulus
Son of the Vestal Virgin Rhea Silvia, ostensibly by the god Mars, the legendary Romulus was Rome's founder and first king. After he and his twin brother Remus had deposed King Amulius of Alba and reinstated the king's brother and their grandfather Numitor to the throne, they decided to build a city in the area where they had been abandoned as infants. After killing Remus in a dispute, Romulus began building the city on the Palatine Hill. His work began with fortifications. He permitted men of all classes to come to Rome as citizens, including slaves and freemen without distinction. He is credited with establishing the city's religious, legal and political institutions. The kingdom was established by unanimous acclaim with him at the helm when Romulus called the citizenry to a council for the purposes of determining their government.
Romulus established the Senate as an advisory council with the appointment of 100 of the most noble men in the community. These men he called patres (from pater, father, head), and their descendants became the patricians. To project command, he surrounded himself with attendants, in particular the twelve lictors. He created three divisions of horsemen (equites), called centuries: Ramnes (Romans), Tities (after the Sabine king) and Luceres (Etruscans). He also divided the populace into 30 curiae, named after 30 of the Sabine women who had intervened to end the war between Romulus and Tatius. The curiae formed the voting units in the popular assemblies (Comitia Curiata).
