In modern historiography, ancient Rome is the Roman civilisation from the founding of the Italian city of Rome in the 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), the Roman Republic (509–27 BC), and the Roman Empire (27 BC – 476 AD) until the fall of the western empire.
Ancient Rome began as an Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian Peninsula. The settlement grew into the city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. It eventually controlled the whole Italian Peninsula, assimilating the Greek culture of Magna Graecia (in southern Italy) and the Etruscan culture in north-central Italy, and then became the dominant power in the Mediterranean region and parts of Europe. At its height it controlled the North African coast, the Iberian and Balkan peninsulas and most of Southern and Western Europe, and much of the Middle East, including Anatolia, the Levant, Egypt, and parts of Mesopotamia and Arabia, and Crimea. That empire was among the largest empires in the ancient world, covering around 5 million square kilometres (1.9 million square miles) in AD 117, with an estimated 50 to 90 million inhabitants, roughly 20% of the world's population at the time. The Roman state evolved from an elective monarchy to a classical republic and then to an increasingly autocratic military dictatorship during the Empire.
Ancient Rome is often grouped into classical antiquity together with ancient Greece, and their similar cultures and societies are known as the Greco-Roman world. Ancient Roman civilisation has contributed to modern language, religion, society, technology, law, politics, government, warfare, art, literature, architecture, and engineering. Rome professionalised and expanded its military and created a system of government called res publica, the inspiration for modern republics such as the United States and France. It achieved impressive technological and architectural feats, such as the empire-wide construction of aqueducts and roads, as well as more grandiose monuments and facilities.
History
Early Italy and the founding of Rome
Archaeological evidence of settlement around Rome starts to emerge c. 1000 BC. Large-scale organisation appears only c. 800 BC, with the first graves in the Esquiline Hill's necropolis, along with a clay and timber wall on the bottom of the Palatine Hill dating to the middle of the 8th century BC. Starting from c. 650 BC, the Romans started to drain the valley between the Capitoline and Palatine Hills, where today sits the Roman Forum. By the 6th century BC, the Romans were constructing the Temple of Jupiter Optimus Maximus on the Capitoline and expanding to the Forum Boarium located between the Capitoline and Aventine Hills.
The Romans themselves had a founding myth, attributing their city to Romulus and Remus, offspring of Mars and a princess of the mythical city of Alba Longa. The sons, sentenced to death, were rescued by a wolf and returned to restore the Alban king and found a city. After a dispute, Romulus killed Remus and became the city's sole founder. The area of his initial settlement on the Palatine Hill was later known as Roma quadrata ('Square Rome'). The story dates at least to the 3rd century BC, and the later Roman antiquarian Marcus Terentius Varro placed the city's foundation to 753 BC. Another legend, recorded by Greek historian Dionysius of Halicarnassus, says that Prince Aeneas led a group of Trojans on a sea voyage to found a new Troy after the Trojan War. They landed on the banks of the Tiber River and a woman travelling with them, Roma, torched their ships to prevent them from leaving again. They named the settlement after her. The Roman poet Virgil recounted this legend in his classical epic poem the Aeneid.
Kingdom
Literary and archaeological evidence is clear on there having been kings in Rome, attested in fragmentary 6th-century BC texts. Long after the abolition of the Roman monarchy, a vestigial rex sacrorum was retained to exercise the monarch's former priestly functions. The Romans believed that their monarchy was elective, with seven legendary kings who were largely unrelated by blood.
Evidence of Roman expansion is clear in the 6th century BC; by its end, Rome controlled a territory of some 780 square kilometres (300 square miles) with a population perhaps as high as 35,000. A palace, the Regia, was constructed c. 625 BC; the Romans attributed the creation of their first popular organisations and the Senate to the regal period as well. Rome also started to extend its control over its Latin neighbours. While later Roman stories like the Aeneid asserted that all Latins descended from the character Aeneas, a common culture is attested to archaeologically. Attested to reciprocal rights of marriage and citizenship between Latin cities—the Jus Latii—along with shared religious festivals, further indicate a shared culture. By the end of the 6th century, most of this area had become dominated by the Romans.
Republic
By the end of the 6th century BC, Rome and many of its Italian neighbours entered a period of turbulence. Archaeological evidence implies some degree of large-scale warfare. According to tradition and later writers such as Livy, the Roman Republic was established c. 509 BC, when the last of the seven kings of Rome, Tarquin the Proud, was deposed and a system based on annually elected magistrates and various representative assemblies was established. A constitution set a series of checks and balances, and a separation of powers. The most important magistrates were the two consuls, who together exercised executive authority such as imperium, or military command. The consuls had to work with the Senate, which was initially an advisory council of the ranking nobility, or patricians, but grew in size and power.
Other magistrates of the Republic include tribunes, quaestors, aediles, praetors and censors. The magistracies were originally restricted to patricians, but were later opened to common people, or plebeians. Republican voting assemblies included the comitia centuriata ('centuriate assembly'), which voted on matters of war and peace and elected men to the most important offices, and the comitia tributa ('tribal assembly'), which elected less important offices.
In the 4th century BC, Rome had come under attack by the Gauls, who now extended their power in the Italian peninsula beyond the Po Valley and through Etruria. On 16 July 390 BC, a Gallic army under the leadership of tribal chieftain Brennus, defeated the Romans at the Battle of the Allia and marched to Rome. The Gauls looted and burned the city, then laid siege to the Capitoline Hill, where some Romans had barricaded themselves, for seven months. The Gauls then agreed to give the Romans peace in exchange for 1000 pounds of gold. According to later legend, the Roman supervising the weighing noticed that the Gauls were using false scales. The Romans then took up arms and defeated the Gauls. Their victorious general Camillus remarked "With iron, not with gold, Rome buys her freedom."
The Romans gradually subdued the other peoples on the Italian peninsula, including the Etruscans. The last threat to Roman hegemony in Italy came when Tarentum, a major Greek colony, enlisted the aid of Pyrrhus of Epirus in 281 BC, but this effort failed as well. The Romans secured their conquests by founding Roman colonies in strategic areas, thereby establishing stable control over the region.
Punic Wars
In the 3rd century BC Rome faced a new and formidable opponent: Carthage, the other major power in the Western Mediterranean. The First Punic War began in 264 BC, when the city of Messana asked for Carthage's help in their conflicts with Hiero II of Syracuse. After the Carthaginian intercession, Messana asked Rome to expel the Carthaginians. Rome entered this war because Syracuse and Messana were too close to the newly conquered Greek cities of Southern Italy and Carthage was now able to make an offensive through Roman territory; along with this, Rome could extend its domain over Sicily.
Carthage was a maritime power, and the Roman lack of ships and naval experience made the path to the victory a long and difficult one for the Roman Republic. Despite this, after more than 20 years of war, Rome defeated Carthage and a peace treaty was signed. Among the reasons for the Second Punic War was the subsequent war reparations Carthage acquiesced to at the end of the First Punic War. The war began with the audacious invasion of Hispania by Hannibal, who marched through Hispania to the Italian Alps. Hannibal's invasion lasted over 16 years, ravaging Italy, but ultimately Carthage was defeated in the decisive Battle of Zama in October 202 BC.
More than a half century after these events, Carthage was left humiliated and the Republic's focus was now directed towards the Hellenistic kingdoms of Greece and revolts in Hispania. However, Carthage, having paid the war indemnity, felt that its commitments and submission to Rome had ceased, a vision not shared by the Roman Senate. The Third Punic War began when Rome declared war against Carthage in 149 BC. Carthage resisted well at the first strike but could not withstand the attack of Scipio Aemilianus, who entirely destroyed the city, enslaved all the citizens and gained control of that region, which became the province of Africa. All these wars resulted in Rome's first overseas conquests (Sicily, Hispania and Africa) and the rise of Rome as a significant imperial power.
Late Republic
After defeating the Macedonian and Seleucid Empires in the 2nd century BC, the Romans became the dominant people of the Mediterranean Sea. The conquest of the Hellenistic kingdoms brought the Roman and Greek cultures in closer contact and the Roman elite, once rural, became cosmopolitan.
Foreign dominance led to internal strife. Senators became rich at the provinces' expense; soldiers, who were mostly small-scale farmers, were away from home longer and could not maintain their land; and the increased reliance on foreign slaves and the growth of latifundia reduced the availability of paid work. Income from war booty, mercantilism in the new provinces, and tax farming created new economic opportunities for the wealthy, forming a new class of merchants, called the equestrians. The lex Claudia forbade members of the Senate from engaging in commerce, so while the equestrians could theoretically join the Senate, they were severely restricted in political power. The Senate squabbled perpetually, repeatedly blocked important land reforms and refused to give the equestrian class a larger say in the government.
Violent gangs of the urban unemployed, controlled by rival Senators, intimidated the electorate through violence. The situation came to a head in the late 2nd century BC under the Gracchi brothers, a pair of tribunes who attempted to pass land reform legislation that would redistribute the major patrician landholdings among the plebeians. Both brothers were killed and the Senate passed reforms reversing the Gracchi brother's actions. This led to the growing divide of the plebeian groups (populares) and equestrian classes (optimates).
Gaius Marius soon became a leader of the Republic, holding the first of his seven consulships (an unprecedented number) in 107 BC by arguing that his former patron Quintus Caecilius Metellus Numidicus was not able to defeat and capture the Numidian king Jugurtha. Marius then started his military reform: in his recruitment to fight Jugurtha, he levied the very poor (an innovation), and many landless men entered the army. Marius was elected for five consecutive consulships from 104 to 100 BC, as Rome needed a military leader to defeat the Cimbri and the Teutones, who were threatening Rome. After Marius's retirement, Rome had a brief peace, during which the Italian socii ('allies') requested Roman citizenship and voting rights. The reformist Marcus Livius Drusus supported their legal process but was assassinated, and the socii revolted against the Romans in the Social War. At one point both consuls were killed; Marius was appointed to command the army together with Lucius Julius Caesar and Lucius Cornelius Sulla.
By the end of the Social War, Marius and Sulla were the premier military men in Rome and their partisans were in conflict, both sides jostling for power. In 88 BC, Sulla was elected for his first consulship and his first assignment was to defeat Mithridates VI of Pontus, whose intentions were to conquer the Eastern part of the Roman territories. However, Marius's partisans managed his installation to the military command, defying Sulla and the Senate. To consolidate his own power, Sulla conducted a surprising and illegal action: he marched to Rome with his legions, killing all those who showed support to Marius's cause. In the following year, 87 BC, Marius, who had fled at Sulla's march, returned to Rome while Sulla was campaigning in Greece. He seized power along with the consul Lucius Cornelius Cinna and killed the other consul, Gnaeus Octavius, achieving his seventh consulship. Marius and Cinna revenged their partisans by conducting a massacre.
Marius died in 86 BC, due to age and poor health, just a few months after seizing power. Cinna exercised absolute power until his death in 84 BC. After returning from his Eastern campaigns, Sulla had a free path to reestablish his own power. In 83 BC he made his second march on Rome and began a time of terror: thousands of nobles, knights and senators were executed. Sulla held two dictatorships and one more consulship, which began the crisis and decline of Roman Republic.
