around the present-day avenue of Gran Vía de Colón, was inhabited since the Bronze Age. The most ancient ruins found in the area belong to an oppidum called Ilturir, founded by the Iberian Bastetani tribe around 650BC. The name Elibyrge is also attested in reference to this area. This settlement became later known as Iliberri or Iliberis. In 44BC Iliberis became a Roman colony and in 27BC it became a Roman municipium named Florentia Iliberritana ('Flourishing Iliberri'). The identification of present-day Granada with the Roman-era Iliberis and the historical continuity between the two settlements has long been debated by scholars. Modern archeological digs on the Albaicín hill have uncovered finds demonstrating the presence of a significant Roman town on that site. Little is known, however, about the history of the city in the period between the end of the Roman era and the 11th century. An important Christian synod circa 300 AD, the Synod of Elvira, took place near this area (the name Elvira being derived from the name Iliberri), but there is no concrete archeological or documentary evidence establishing the exact location of the meeting. It may have taken place in the former Roman town or it may have taken place somewhere in the surrounding region, which was known as Elvira. Founding and early history The Umayyad conquest of Hispania, starting in 711AD, brought large parts of the Iberian Peninsula under Moorish control and established al-Andalus. The earliest Arabic historical sources mention that a town named Qashtīliya, later known as Madīnat Ilbīra (Elvira), was located on the southern slopes of the Sierra de Elvira mountains (near present-day Atarfe) and became the most important settlement in the area. A smaller settlement and fortress (ḥiṣn) named Ġarnāṭa (also transliterated as Gharnāṭa) existed on the south side of the Darro River or on the site of the current Albaicín neighbourhood. The latter had a mainly Jewish population and thus was also known as Gharnāṭat al-Yahūd ("Gharnāṭa of the Jews"). The district around the city was known as Kūrat Ilbīra (roughly "Province of Elvira"). After 743 the town of Ilbīra was settled by soldiers from the region of Syria who played a role in supporting Abd al-Rahman I, the founder of the Emirate of Córdoba and a new Umayyad dynasty. In the late 9th century, during the reign of Abdallah (r. 844–912), the city and its surrounding district were the site of conflict
