Trier
Trier (/trɪər/ TREER,[3][4] German: [tʁiːɐ̯] (listen)
; Luxembourgish: Tréier [ˈtʀəɪɐ] (listen)), formerly known in English as Trèves (/trɛv/ TREV;[5][6]) 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 Celts in the late 4th century BC as Treuorum and conquered 300 years later by the Romans, who renamed it Augusta Treverorum ("The City of Augustus among the Treveri"), Trier is considered Germany's oldest city.[7][8] It is also the oldest seat of a bishop north of the Alps. 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.
With an approximate population of 105,000, Trier is the fourth-largest city in its state, after Mainz, Ludwigshafen, and Koblenz.[9] The nearest major cities are Luxembourg (50 km or 31 mi to the southwest), Saarbrücken (80 kilometres or 50 miles southeast), and Koblenz (100 km or 62 mi northeast).
The University of Trier, the administration of the Trier-Saarburg district and the seat of the ADD (Aufsichts- und Dienstleistungsdirektion), which until 1999 was the borough authority of Trier, and the Academy of European Law (ERA) are all based in Trier. It is one of the five "central places" of the state of Rhineland-Palatinate. Along with Luxembourg, Metz and Saarbrücken, fellow constituent members of the QuattroPole union of cities, it is central to the greater region encompassing Saar-Lor-Lux (Saarland, Lorraine and Luxembourg), Rhineland-Palatinate, and Wallonia.
The first traces of human settlement in the area of the city show evidence of linear pottery settlements dating from the early Neolithic period. Since the last pre-Christian centuries, members of the Celtic tribe of the Treveri settled in the area of today's Trier.[10] The city of Trier derives its name from the later Latin locative in Trēverīs for earlier Augusta Treverorum. According to the Archbishops of Trier, in the Gesta Treverorum, the founder of the city of the Trevians is Trebeta. German historian Johannes Aventinus also credited Trebeta with building settlements at Metz, Mainz, Basel, Strasbourg, Speyer and Worms.
The historical record describes the Roman Empire subduing the Treveri in the 1st century BC and establishing Augusta Treverorum about 16 BC.[11] The name distinguished it from the empire's many other cities honoring the first Roman emperor, Augustus. The city later became the capital of the province of Belgic Gaul; after the Diocletian Reforms, it became the capital of the prefecture of the Gauls, overseeing much of the Western Roman Empire. In the 4th century, Trier was one of the largest cities in the Roman Empire with a population around 75,000 and perhaps as much as 100,000.[12][13][14][15] The Porta Nigra ("Black Gate") dates from this era. A residence of the Western Roman emperor, Roman Trier was the birthplace of Saint Ambrose. Sometime between 395 and 418, probably in 407 the Roman administration moved the staff of the Praetorian Prefecture from Trier to Arles. The city continued to be inhabited but was not as prosperous as before. However, it remained the seat of a governor and had state factories for the production of ballistae and armor and woolen uniforms for the troops, clothing for the civil service, and high-quality garments for the Court. Northern Gaul was held by the Romans along a line from north of Cologne to the coast at Boulogne through what is today southern Belgium until 460. South of this line, Roman control was firm, as evidenced by the continuing operation of the imperial arms factory at Amiens.
