"Trier" Trier by AcornMan

One of the oldest cities in Germany, Trier has played an important role in its history since Roman times and retains many Roman monuments. Founded by Augustus c.15 BC, the city was made (1st cent.) the capital of the Roman province of Belgica and later became (3d cent.) the capital of the prefecture of Gaul; it was named after the Treveri, a people of E Gaul. Under the Roman Empire Trier attained a population of c.50,000 and became a major commercial center, with a large wine trade. It was a frequent residence of the Western emperors from c.295 until its capture (early 5th cent.) by the Franks.

The city was made an episcopal see in the 4th cent. and an archiepiscopal see c.815. Under the rule of the archbishops, Trier flourished as a commercial and cultural center. Trier was the seat of a university from 1473 until it was occupied by the French in 1797. The archbishopric of Trier was secularized and was formally ceded to France in 1801 by the Treaty of Lunýville. At the Congress of Vienna the city and most of the archbishopric were awarded (1815) to Prussia; territory E of the Rhine was given to Nassau and, with Nassau, passed to Prussia in 1866. Trier again became an episcopal see in 1821. It was occupied by France after World War I and suffered considerable damage in World War II.
