The Turoni or Turones were a Gallic tribe of dwelling in the later Touraine region during the Iron Age and the Roman period.
They were among the first tribes to give support to the Gallic coalition against Rome led by Vercingetorix in 52 BC, then to the revolt of Sacrovir in 21 AD.
Geoffrey of Monmouth later expanded this story in the Historia Regum Britanniae, where Tours was named after Brutus' nephew, also called Turnus, who had died fighting against Goffar the Pictone, king of Aquitaine.
[7] The city of Tours, attested in the 6th c. AD as apud Toronos (in civitate Turonus in 976, Turonis in 1205, Tors in 1266), and the Touraine region, attested in 774 as Turonice civitatis (in pago Turonico in 983, vicecomes Turanie in 1195–96, Touraine in 1220), are named after the Gallic tribe.
[10] During the Roman era, the chief town of the Turonian territory was Caesarodunum, corresponding the modern city of Tours.
