Articles relating to the Treveri, a Germanic or Celtic tribe of the Belgae group who inhabited the lower valley of the Moselle from around 150 BCE, if not earlier,until their displacement by the Franks. Their domain lay within the southern fringes of the Silva Arduenna (Ardennes Forest), a part of the vast Silva Carbonaria, in what are now Luxembourg, southeastern Belgium and western Germany; its centre was the city of Trier (Augusta Treverorum), to which the Treveri give their name.
