The concept of Italic peoples is widely used in linguistics and historiography of ancient Italy. In a strict sense, commonly used in linguistics, it refers to the Osco-Umbrians and Latino-Faliscans, speakers of the Italic languages, a subgroup of the Indo-European language family. In a broader sense, commonly used in historiography, all the ancient peoples of Italy are referred to as Italic peoples, including the non-Indo-European ones, as Rhaetians, Ligures and Etruscans. As the Latins achieved a dominant position among these tribes, by virtue of the expansion of the Roman civilization, the other Italic tribes adopted Latin language and culture as part of the process of Romanization.
