Teutons, or Teutones, a barbarian people who invaded Roman lands in the second century B.C. They may have been either Germanic or Celtic; all that is known definitely is that they were allies of the Cimbri, who were also either a Germanic or Celtic people. The Teutons entered Gaul sometime after 113 B.C. and were decisively defeated by the Romans in 102 B.C. at Aquae Sextiae (present Aix, France). In modern times the word Teutoniccame to refer to the German people and to anything Germanic—for example, the Germanic sub-family of the Indo-European language family.
