Roman Republic
The Roman Republic was the era of classical Roman civilisation beginning with the overthrow of the Roman Kingdom and ending in 27 BC with the establishment of the Roman Empire following the War of Actium. During this period, Rome's control expanded from the city's immediate surroundings to hegemony over the entire Mediterranean world.
Roman society at the time was primarily a cultural mix of Latin and Etruscan societies, as well as of Sabine, Oscan, and Greek cultural elements, which is especially visible in the ancient Roman religion and its pantheon. Its political organisation developed at around the same time as direct democracy in ancient Greece, with collective and annual magistracies, overseen by a senate. There were annual elections, but the republican system was an elective oligarchy, not a democracy, with a number of powerful families largely monopolising the senior magistracies. Roman institutions underwent considerable changes throughout the Republic to adapt to difficulties such as the creation of promagistracies to rule its conquered provinces and, after the Social War during the late Republic, the inclusion of peninsular Italians as citizens and senators.
Unlike the Pax Romana of the Roman Empire, republican Rome was in a state of near-perpetual war. Its first enemies were its Latin and Etruscan neighbours, as well as the Gauls, who sacked Rome around 387 BC. After the Gallic sack, Rome conquered most of the Italian peninsula in a century and became one of the Mediterranean great powers. Its greatest strategic rival was Carthage, against which it waged three wars. Rome defeated Carthage at the Battle of Zama in 202 BC and in the following decades became the dominant power in the ancient Mediterranean world. It then embarked on a long series of difficult conquests, defeating Philip V and Perseus of Macedon, Antiochus III of the Seleucid Empire, the Lusitanian Viriathus, the Numidian Jugurtha, the Pontic king Mithridates VI, Vercingetorix of the Arverni tribe of Gaul, and the Egyptian queen Cleopatra.
At home, during the Conflict of the Orders, the patricians, the closed oligarchic elite, came into conflict with the more numerous plebs; this was resolved peacefully, with the plebs achieving political equality by the 4th century BC. The late Republic, from 133 BC onward, saw substantial domestic strife, often anachronistically seen as a conflict between optimates and populares, referring to conservative and reformist politicians, respectively. The Social War between Rome and its Italian allies over citizenship and Roman hegemony in Italy greatly expanded the scope of civil violence. Mass slavery also contributed to three Servile Wars. Political violence at home coupled with powerful semi-autonomous generals led to civil wars that broke the Republic. The first involved Marius and Sulla. After a generation, the Republic fell into civil war again in 49 BC between Julius Caesar and Pompey. Despite his victory and appointment as dictator for life, Caesar was assassinated in 44 BC. Caesar's heir Octavian and lieutenant Mark Antony defeated Caesar's assassins in 42 BC, but they split, eventually resulting in Antony's defeat alongside his ally and lover Cleopatra at the Battle of Actium in 31 BC. Octavian, the victor, then became the dominant force in Roman politics; Octavian's receipt of the title Augustus from the Senate in 27 BC is often seen to mark the end of the Republic and the beginning of the Roman Empire.
History
Founding
Rome had been ruled by monarchs since its foundation. These monarchs were elected, for life, by the men of the Roman Senate. The last Roman monarch was called Tarquin the Proud, who in traditional histories was expelled from Rome in 509 BC because his son, Sextus Tarquinius, raped a noblewoman, Lucretia. The tradition asserted that the monarchy was abolished in a revolution led by the semi-mythical Lucius Junius Brutus and the king's powers were then transferred to two separate consuls elected to office for a term of one year; each was capable of checking his colleague by veto. Most modern scholarship describes these accounts as the quasi-mythological detailing of an aristocratic coup within Tarquin's own family or a consequence of an Etruscan occupation of Rome rather than a popular revolution.Rome in Latium
Early campaigns
According to Rome's traditional histories, Tarquin made several attempts to retake the throne, including the Tarquinian conspiracy, which involved Brutus's own sons, the war with Veii and Tarquinii, and finally the war between Rome and Clusium. The attempts to restore the monarchy did not succeed.The first Roman republican wars were wars of expansion. One by one, Rome defeated both the persistent Sabines and the local cities. Rome defeated its rival Latin cities in the Battle of Lake Regillus in 496 BC, the Battle of Ariccia in 495 BC, the Battle of Mount Algidus in 458 BC, and the Battle of Corbio in 446 BC. But it suffered a significant defeat at the Battle of the Cremera in 477 BC, wherein it fought against the most important Etruscan city, Veii; this defeat was later avenged at the Battle of Veii in 396 BC, wherein Rome destroyed the city. By the end of this period, Rome had effectively completed the conquest of its immediate Etruscan and Latin neighbours and secured its position against the immediate threat posed by the nearby Apennine hill tribes.
Plebeians and patricians
Beginning with their revolt against Tarquin, and continuing through the early years of the Republic, Rome's patrician aristocrats were the dominant force in politics and society. They initially formed a closed group of about 50 large families, called gentes, who monopolised Rome's magistracies, state priesthoods, and senior military posts. The most prominent of these families were the Cornelii, Aemilii, Claudii, Fabii, and Valerii. The leading families' power, privilege and influence derived from their wealth, in particular from their landholdings, their position as patrons, and their numerous clients.The vast majority of Roman citizens were commoners of various social degrees. They formed the backbone of Rome's economy, as smallholding farmers, managers, artisans, traders, and tenants. In wartime, they could be summoned for military service. Most had little direct political influence. During the early Republic, the plebs emerged as a self-organised, culturally distinct group of commoners, with its own internal hierarchy, laws, customs, and interests. Plebeians had no access to high religious and civil office. For the poorest, one of the few effective political tools was their withdrawal of labour and services, in a secessio plebis; the first such secession occurred in 494 BC, in protest at the abusive treatment of plebeian debtors by the wealthy during a famine. The patrician Senate was compelled to give them direct access to the written civil and religious laws and to the electoral and political process. To represent their interests, the plebs elected tribunes, who were personally sacrosanct, immune to arbitrary arrest by any magistrate, and had veto power over legislation.
Celtic invasion of Italy
By 390 BC, several Gallic tribes were invading Italy from the north. The Romans met the Gauls in pitched battle at the Battle of Allia River around 390–387 BC. The battle was fought at the confluence of the Tiber and Allia rivers, 11 Roman miles north of Rome. The Romans were routed and subsequently Rome was sacked by the Senones. There is no destruction layer at Rome around this time, indicating that if a sack occurred, it was largely superficial.Roman expansion in Italy
Wars against Italian neighbours
From 343 to 341 BC, Rome won two battles against its Samnite neighbours, but was unable to consolidate its gains, due to the outbreak of war with former Latin allies. In the Latin War, Rome defeated a coalition of Latins at the battles of Vesuvius and the Trifanum. The Latins submitted to Roman rule.A Second Samnite War began in 327 BC. The war ended with Samnite defeat at the Battle of Bovianum in 305 BC. By 304 BC, Rome had annexed most Samnite territory and begun to establish colonies there, but in 298 BC the Samnites rebelled, and defeated a Roman army, in a Third Samnite War. After this success, it built a coalition of several previous enemies of Rome. The war ended with Roman victory in 290 BC.
At the Battle of Populonia, in 282 BC, Rome finished off the last vestiges of Etruscan power in the region.
Rise of the plebeian nobility
In the 4th century, plebeians gradually obtained political equality with patricians. The first plebeian consular tribunes were elected in 400. The reason behind this sudden gain is unknown, but it was limited as patrician tribunes retained preeminence over their plebeian colleagues. In 385 BC, the former consul and saviour of the besieged capital, Marcus Manlius Capitolinus, is said to have sided with the plebeians, ruined by the sack and largely indebted to patricians. According to Livy, Capitolinus sold his estate to repay the debt of many of them, and even went over to the plebs, the first patrician to do so. Nevertheless, the growing unrest he had caused led to his trial for seeking kingly power; he was sentenced to death and thrown from the Tarpeian Rock.Between 376 and 367 BC, the tribunes of the plebs Gaius Licinius Stolo and Lucius Sextius Lateranus continued the plebeian agitation and pushed for an ambitious legislation, known as the leges Liciniae Sextiae. The most important bill opened the consulship to plebeians. Other tribunes controlled by the patricians vetoed the bills, but Stolo and Lateranus retaliated by vetoing the elections for five years while being continuously reelected by the plebs, resulting in a stalemate. In 367 BC, they carried a bill creating the decemviri sacris faciundis, a college of ten priests, of whom five had to be plebeians, thereby breaking patricians' monopoly on priesthoods. The resolution of the crisis came from the dictator Camillus, who made a compromise with the tribunes: he agreed to their bills, and they in return consented to the creation of the offices of praetor and curule aediles, both reserved to patricians. Lateranus became the first plebeian consul in 366 BC; Stolo followed in 361 BC.
Soon after, plebeians were able to hold both the dictatorship and the censorship. The four-time consul Gaius Marcius Rutilus became the first plebeian dictator in 356 BC and censor in 351 BC. In 342 BC, the tribune of the plebs Lucius Genucius passed his leges Genuciae, which abolished interest on loans, in a renewed effort to tackle indebtedness; required the election of at least one plebeian consul each year; and prohibited magistrates from holding the same magistracy for the next ten years or two magistracies in the same year. In 339 BC, the plebeian consul and dictator Quintus Publilius Philo passed three laws extending the plebeians' powers. His first law followed the lex Genucia by reserving one censorship to plebeians, the second made plebiscites binding on all citizens, and the third required the Senate to give its prior approval to plebiscites before they became binding on all citizens.
During the early Republic, consuls chose senators from among their supporters. Shortly before 312 BC, the lex Ovinia transferred this power to the censors, who could only remove senators for misconduct, thus appointing them for life. This law strongly increased the power of the Senate, which was by now protected from the influence of the consuls and became the central organ of government. In 312 BC, following this law, the patrician censor Appius Claudius Caecus appointed many more senators to fill the new limit of 300, including descendants of freedmen, which was deemed scandalous. Caecus also launched a vast construction programmee, building the first aqueduct, the aqua Appia, and the first Roman road, the via Appia.
In 300 BC, the two tribunes of the plebs Gnaeus and Quintus Ogulnius passed the lex Ogulnia, which created four plebeian pontiffs, equalling the number of patrician pontiffs, and five plebeian augurs, outnumbering the four patricians in the college. The Conflict of the Orders ended with the last secession of the plebs around 287. The dictator Quintus Hortensius passed the lex Hortensia, which reenacted the law of 339 BC, making plebiscites binding on all citizens, while also removing the requirement for prior Senate approval. These events were a political victory of the wealthy plebeian elite, who exploited the economic difficulties of the plebs for their own gain: Stolo, Lateranus, and Genucius bound their bills attacking patricians' political supremacy with debt-relief measures. As a result of the end of the patrician monopoly on senior magistracies, many small patrician gentes faded into history during the 4th and 3rd centuries BC due to the lack of available positions. About a dozen remaining patrician gentes and twenty plebeian ones thus formed a new elite, called the nobiles.
