The Aventine Hill is one of the Seven Hills on which ancient Rome was built. It belongs to Ripa, the twelfth rione, or ward, of Rome. The part of the city that stands on it is sometimes referred to as Reme, or Ream. According to Roman tradition, the Aventine was not included within Rome's original foundation, and lay outside the city's ancient sacred boundary (pomerium). The Roman historian Livy reports that Ancus Marcius, Rome's fourth king, defeated the Latins of Politorium, and resettled them there. The Roman geographer Strabo credits Ancus with the building of a city wall to incorporate the Aventine. Others credit the same wall to Rome's sixth king, Servius Tullius. The remains known as the Servian Wall used stone quarried at Veii, which was not conquered by Rome until c.393 BC, so the Aventine might have been part-walled, or an extramural suburb. The Aventine appears to have functioned as some kind of staging post for the legitimate ingress of foreign peoples and foreign cults into the Roman ambit. During the late regal era, Servius Tullius built a temple to Diana on the Aventine, as a Roman focus for the new-founded Latin League. The Aventine's outlying position, its longstanding association with Latins and plebeians and its extra-pomerial position reflect its early marginal status. At some time around 493 BC, soon after the expulsion of Rome's last King and the establishment of the Roman Republic, the Roman senate provided a temple for the so-called Aventine Triad of Ceres, Liber and Libera, patron deities of the Roman commoners or plebs; the dedication followed one of the first in a long series of threatened or actual plebeian secessions. The temple overlooked the Circus Maximus and the Temple of Vesta, and faced the Palatine Hill. It became an important repository for plebeian and senatorial records. It is presumed that the Aventine was state-owned public land; in c.456 BC a Lex Icilia allowed or granted the plebs property rights there. By c.391 BC, the city's overspill had overtaken the Aventine and the Campus Martius, and left the city vulnerable to attack; around that year, the Gauls overran and temporarily held the city. After this, the walls were rebuilt or extended to properly incorporate the Aventine; this is more or less coincident with the increasing power and influence of the Aventine-based plebeian aediles and tribunes in Roman public affairs, and the rise of a plebeian nobility. Rome absorbed many more foreign deities via the Aventine: "No other location approaches concentration of foreign cults". In 392 BC, Camillus established a temple there to Juno Regina. Later introductions include Summanus, c. 278, Vortumnus c. 264, and at some time before the end of the 3rd century, Minerva. The Aventine was also the site of the Baths of Decius, built in 252.
