The spelling variants Treveri and Treviri are found in Latin texts from the time of Caesar's De Bello Gallico to Tacitus's Annales.

The Galatians were still speaking the Galatian language ( Gaulish ) in the time of St. Jerome ( 347 – 420 AD ), who wrote that the Galatians of Ancyra and the Treveri of Trier ( in what is now the German Rhineland ) spoke the same language ( Comentarii in Epistolam ad Galatos, 2. 3, composed c. 387 ).

By and large, the Treveri were more co-operative with the Romans, who completed their occupation in 53 BC under Julius Caesar, than most Gallic tribes.

At the earliest historical period, the territories between the Ardennes and the Rhine were occupied by the Treveri, the Eburones and other Celtic tribes, who, however, were all more or less modified and influenced by their Germanic neighbours.

Upper Germania was occupied by Gaulish tribes including the Helvetii, Sequani, Leuci, and Treveri, and, on the north bank of the middle Rhine, the remnant of the Germanic troops that had attempted to take Vesontio under Ariovistus, but who were defeated by Caesar in 58 BC.

Tacitus also records that the Nervii and Treveri were also eager to claim Germanic rather than Gaulish origin.

The medieval Gesta Treverorum compiled by monks of Trier claims that the Belgae were descendants of Trebeta, an otherwise unattested legendary founder of Trier, the Roman Augusta Treverorum, " Augusta of the Treveri ".

In other directions, their neighbours in Roman times were the Belgic Nervii on the west and the Remi and Treveri to the south, all tribes who had been in those regions since before Caesar's campaign.

Caesar mentions that the Segni and the Condrusi lived between the Treveri and the Eburones, and that the Condrusii and Eburones were clients of the Treveri.

Archaeological evidence suggests that the Treveri were divided into five cantons centred respectively on the oppida of the Titelberg, Wallendorf, Kastel, Otzenhausen and the Martberg.

External to the Treveri, but subject to them as clients, were the Eburones and perhaps also the Caeroesi and Paemani.

Strabo says that their Nervian and Tribocan neighbours were Germanic peoples who by that point had settled on the left bank of the Rhine, while the Treveri are implied to be Gaulish.

Originally the oppida of the Titelberg, Wallendorf, Kastel, Otzenhausen and the Martberg were roughly equal in significance ; however, sometime between 100 and 80 BCE, the Titelberg experienced an upsurge of growth which made it " the central oppidum of the Treveri ".

The Treveri remained neutral during the revolt of Vercingetorix, and were attacked again by Labienus after it.

On the whole, the Treveri were more successful than most Gallic tribes in cooperating with the Romans.

The Treveri were originally polytheists, and following the Roman conquest many of their gods were identified with Roman equivalents or coupled with Roman gods.

Among the deities unique to the Treveri were Intarabus, Ritona, Inciona and Veraudunus, and the Xulsigiae.

By the 2nd century CE, wealthy Treveri were building elaborate funerary monuments such as the World Heritage-listed Igel Column, or the sculpted grave-stones found at Arlon, Neumagen and Buzenol, all of which depict the deceased's livelihood and / or interests during life.

When the Tencteri and Usipetes, who were Germanic tribes, crossed the Rhine from Germania ( 55 BCE ), they first fell on the Menapii, and then advanced into the territories of the Eburones and Condrusi, who were both " under the protection of " the Treveri to the south.

The Pilier des nautes links him with sailors and with commerce, suggesting that he was also associated with material wealth as does the coin pouch from the Cernunnos of Rheims ( Marne, Champagne, France )— in antiquity, Durocortorum, the civitas capital of the Remi tribe — and the stag vomiting coins from Niedercorn-Turbelslach ( Luxembourg ) in the lands of the Treveri.

The Celtic tribe in what is now Luxembourg during and after the La Tène period was known as the Treveri.

At the time of the Roman conquest the region of Bastogne was inhabited by the Treveri, a tribe of Gauls.

Apart from being under the protection of the Treveri, the Eburones also had close dealings with the Nervii, a large Belgic ( but possibly not Germanic, or less Germanic ) tribe to the southwest of them, with their later Roman capital in Bavay.

Julius Indus was a nobleman of the Gaulish Treveri tribe.

The history of Clemency goes back to the 1st century BC when the Treveri, a Celtic tribe, inhabited the region around Titelberg, a large oppidum near Rodange.

The Ala Gallorum Indiana (" Indus's Wing of Gauls ") was a Gaulish auxiliary cavalry unit in the Roman army, named after its first commander, Julius Indus, a nobleman of the Treveri who helped put down a Gaulish rebellion in 21.

The Romans quickly re-established cordial relations with the Treveri under Indus, who promised obedience to Rome ; in contrast, they completely annihilated the Aedui who had sided with Sacrovir.

His tombstone was erected by his wife Julia Pacata, daughter of Julius Indus, a nobleman of the Gaulish Treveri who became commander of the Ala Gallorum Indiana cavalry unit.

The child was born at Treveri, near the village of Ambitarvium, just before the junction of the Moselle River and the Rhine River ( modern Koblenz Germany ).

She was particularly worshipped by the Treveri in the Moselle Valley.

Additional evidence is given by one inscription on a metal plaque from Steinsel-Rëlent in Luxembourg, in the territory of the Celtic Treveri.

It is also found in several placenames, such as the Ardennes Woods ( Arduenna silva ), the Forest of Arden in England, in personal names Arduunus and Arda — the latter from coinage of the Treveri, ( RIG-4, 36-43 ) — and the Galatian Αρδή.

The Treveri suffered from their proximity to the Rhine frontier during the Crisis of the Third Century.

The Treveri suffered further devastation from the Alamanni in 275, following which, according to Jeannot Metzler, " The great majority of agricultural domains lay waste and would never be rebuilt ".

The territory of the Treveri had formed part of the Hunsrück-Eifel culture, covering the Hallstatt D and La Tène A-B periods ( from 600 to 250 BCE ).

Trade goods made their way to the Treveri from Etruria and the Greek world ; monetary evidence suggests strong trade links with the neighbouring Remi.

The Eburones, encouraged by messages from the Treveri king Indutiomarus, and headed by their two kings, Ambiorix and Cativolcus, attacked the Roman camp ; and after inducing the Romans to leave their stronghold on the promise of a safe passage, massacred nearly all of them ( approximately 6000 men ).

As early as 500 BC, the Treveri, a people of mixed Celtic and Germanic stock, from whom the Latin name for the city of Trier, Augusta Treverorum, is also derived, settled in the region around Zeltingen-Rachtig.
