context_page_description: The history of Rome includes the history of the city of Rome as well as the civilisation of ancient Rome. Roman history has been influential on the modern world, especially in the history of the Catholic Church, and Roman law has influenced many modern legal systems. Roman history can be divided into the following periods:
  Pre-historical and early Rome, covering Rome's earliest inhabitants and the legend of its founding by Romulus.
  The period of Etruscan dominance and the Regal Period, in which according to tradition, Romulus was the first of seven kings.
  The Roman Republic, which commenced in 509 BC when kings were replaced with rule by elected senators. The period was marked by vast expansion of Roman territory. During the 5th century BC, Rome gained regional dominance in Latium. With the Punic Wars from 264 to 146 BC, Ancient Rome gained dominance over the Western Mediterranean, displacing Carthage as the dominant regional power.
  The Roman Empire - with the rise of Julius Caesar, the Republic waned, and by all measures concluded after a period of civil war and the victory of Octavian, the adopted son of Caesar in 27 BC over Mark Antony.
context_section_description: From 1048 to 1257, the papacy experienced increasing conflict with the leaders and churches of the Holy Roman Empire and the Byzantine (Eastern Roman) Empire. The latter culminated in the East-West Schism, dividing the Catholic Church and Eastern Orthodox Church. From 1257 to 1377, the pope, though the bishop of Rome, resided in Viterbo, Orvieto, and Perugia, and then Avignon. The return of the popes to Rome after the Avignon Papacy was followed by the Western Schism: the division of the western church between two, and for a time three, competing papal claimants.
  In this period the renovated Church was again attracting pilgrims and prelates from all the Christian world, and money with them: even with a population of only 30,000, Rome was again becoming a city of consumers dependent upon the presence of a governmental bureaucracy. In the meantime, Italian cities were acquiring increasing autonomy, mainly led by new families which were replacing the old aristocracy with a new class formed by entrepreneurs, traders and merchants. After the sack of Rome by the Normans in 1084, the rebuilding of the city was supported by powerful families such as the Frangipane family and the Pierleoni family, whose wealth came from commerce and banking rather than landholdings. Inspired by neighbouring cities like Tivoli and Viterbo, Rome's people began to consider adopting a communal status and gaining a substantial amount of freedom from papal authority.
  Led by Giordano Pierleoni, the Romans rebelled against the aristocracy and Church rule in 1143. The Senate and the Roman Republic, the Commune of Rome, were born again. Through the inflammatory words of preacher Arnaldo da Brescia, an idealistic, fierce opponent of ecclesiastical property and church interference in temporal affairs, the revolt that led to the creation of the Commune of Rome continued until it was put down in 1155, though it left its mark on the civil government of the Eternal City for centuries. 12th-century Rome, however, had little in common with the empire which had ruled over the Mediterranean some 700 years before, and soon the new Senate had to work hard to survive, choosing an ambiguous policy of shifting its support from the Pope to the Holy Roman Empire and vice versa as the political situation required. At Monteporzio, in 1167, during one of these shifts, in the war with Tusculum, Roman troops were defeated by the imperial forces of Frederick Barbarossa. Luckily, the winning enemies were soon dispersed by a plague and Rome was saved.
  In 1188 the new communal government was finally recognised by Pope Clement III. The Pope had to make large cash payments to the communal officials, while the 56 senators became papal vassals. The Senate always had problems in the accomplishment of its function, and various changes were tried. Often a single Senator was in charge. This sometimes led to tyrannies, which did not help the stability of the newborn organism.
