Marche was known in ancient times as the Picenum territory. The Picens or Picentes (Ancient Greek: Πίκεντες) were the Italic tribe who lived in Picenum during the Iron Age. Many artefacts from their time are exhibited in National Archaeological Museum of the Marche Region in Ancona. In the fourth century BC, the northern area was occupied by the Senones, a tribe of Gauls. The Battle of Sentinum was fought in Marche in 295 BC; afterwards, the Romans founded numerous colonies in the area, connected to Rome by the Via Flaminia and the Via Salaria. Ascoli was a seat of Italic resistance during the Social War (91–88 BC).
