The Ligures (singular Ligus or Ligur; English: Ligurians, Greek: Λίγυες) were an ancient Indo-European people who appear to have originated in, and gave their name to, Liguria, a region of north-western Italy. Elements of the Ligures appear to have migrated to other areas of western Europe, including the Iberian peninsula.
Little is known of the Old Ligurian language. It is generally believed to have been an Indo-European language with particularly strong Celtic affinities, as well as similarities to Italic languages. Only some proper names have survived, such as the inflectional suffix -asca or -asco "village".
Because of the strong Celtic influences on their language and culture, they were known in antiquity as Celto-Ligurians (in Greek Κελτολίγυες Keltolígues).
According to Plutarch, the Ligurians called themselves Ambrones, which could indicate a relationship with the Ambrones of northern Europe.
Strabo tells that they were of a different race from the Celts (by which he means Gauls), who inhabited the rest of the Alps, though they resembled them in their mode of life.
Aeschylus represents Hercules as contending with the Ligures on the stony plains, near the mouths of the Rhone, and Herodotus speaks of Ligures inhabiting the country above Massilia (modern Marseilles, founded by the Greeks).
Thucydides also speaks of the Ligures having expelled the Sicanians, an Iberian tribe, from the banks of the river Sicanus, in Iberia.
