Treveri in the context of "Silva Carbonaria"

Trier (/trɪər/ TREER, German: [tʁiːɐ̯] ; Luxembourgish: Tréier [ˈtʀɜɪ̯ɐ] ), formerly and traditionally known in English as Trèves (/trɛv/ TREV, French: [tʁɛv] ) and Triers (see also names in other languages), is a city on the banks of the Moselle in Germany. It lies in a valley between low vine-covered hills of red sandstone in the west of the state of Rhineland-Palatinate, near the border with Luxembourg and within the important Moselle wine region.

Founded by the Romans in the late 1st century BC as Augusta Treverorum ("The City of Augustus among the Treveri"), Trier is considered Germany's oldest city. It is also the oldest seat of a bishop north of the Alps. Trier was one of the four capitals of the Roman Empire during the Tetrarchy period in the late 3rd and early 4th centuries. In the Middle Ages, the archbishop-elector of Trier was an important prince of the Church who controlled land from the French border to the Rhine. The archbishop-elector of Trier also had great significance as one of the seven electors of the Holy Roman Empire. Because of its significance during the Roman and Holy Roman empires, several monuments and cathedrals within Trier are listed as a UNESCO World Heritage Site.

The miliarense (neuter form of the late Latin miliarensis, "pertaining to a thousand"; plural: miliarensia) was a large silver coin, introduced to the late Roman monetary system in the early 4th century. It was struck with variable fineness, generally with a weight between 3.8 and 6.0 grams, and a diameter of c. 23–24 mm. The miliarense was struck first under Constantine the Great (r. 306–337).

There were two kinds of miliarense coins: light and heavy. It took 14 heavy miliarensia and 18 light miliarensia to equal one gold solidus (as also introduced by Constantine). Miliarensia are highly desired by numismatists of the present day, due to both the rarity of the denomination (far less common than the siliqua) and the often exquisite execution of both bust and reverse types, which led to many being used as pendants or mounted in antiquity.

Gallia Belgica ("Belgic Gaul") was a province of the Roman Empire located in the north-eastern part of Roman Gaul, in what is today primarily northern France, Belgium, and Luxembourg, along with parts of the Netherlands and Germany.

Before the Roman province came into existence in about 50 BC, the region was conquered by Julius Caesar during his Gallic Wars. His report, the Commentarii de Bello Gallico, described Belgic Gaul as one of the three parts of Gaul (Tres Galliæ), the other two being Gallia Aquitania and Gallia Lugdunensis. Belgica stretched from the Marne and Seine rivers, which Caesar described as a cultural boundary between the Belgae and the Celtic Gauls. In the north and east it stretched all the way to the Rhine. The official Roman province of this name was later created by emperor Augustus in 22 BC, and named after the Belgae, as the largest tribal confederation in the area. However, it also included the territories of the Treveri, Mediomatrici, Leuci, Sequani, and others who Caesar did not explicitly designate as Belgic.

Augusta Treverorum (Latin for "City of Augustus in the Land of the Treveri") was a Roman city on the Moselle River, from which modern Trier emerged.

The date of the city's founding is placed between the construction of the first Roman bridge in Trier (18/17 BC) and the late reign of Augustus († 14 AD). In the Roman Empire, Trier formed the main town of the civitas of the Treverians, where several ten thousand people lived, and belonged to the province of Gallia Belgica. Roman Trier gained particular importance in late antiquity: between the late 3rd and late 4th centuries several rulers, including Constantine the Great, used the city as one of the western imperial residences, sponsoring monumental buildings such as the Trier Imperial Baths and the Basilica of Constantine. With a high five-digit population in 300, Augusta Treverorum, now sometimes called Treveris, was the largest city north of the Alps and thus had the status of a global city.

The Eburones were the largest of the Germanic peoples dwelling in the northeast of Gaul - the so-called Germani cisrhenani - during the Gallic Wars of Julius Caesar in the years 58-50 BC. They fought and eventually lost against the Roman forces of Caesar in alliance with their fellow Belgae of northern Gaul, and the Treveri who were their neighbours to the south. They do not appear in historical records after this.

Scholars debate the exact extent of their country, but they lived in a region west of the Rhine, north of the Ardennes, and near the Meuse. This roughly corresponds today with the southern Netherlands, eastern Belgium and the German Rhineland.

Indutiomarus (died 53 BC) was a leading aristocrat of the Treveri (the people of the area around present-day Trier) at the time of Julius Caesar's conquest of Gaul. He was the head of the anti-Roman party and the political rival of his pro-Roman son-in-law Cingetorix for "supreme power" in the state.
