Tongeren (Dutch: [ˈtɔŋərə(n)] ⓘ; French: Tongres [tɔ̃ɡʁ]; German: Tongern [ˈtɔŋɐn]; Limburgish: Tóngere [ˈtʊŋəʀə])[tone?]

Caesar referred to the fort of the Eburones as Aduatuca, and this has led to a widely accepted proposal that this can be equated to Tongeren.

But many modern writers believe that the Gallo-Roman population of the area contained a significant amount of more recent Germanic immigrants from across the Rhine.

Located on the important road linking Cologne to Bavay via the relay of Liberchies, and surrounded by the fertile lands of the Hesbaye region, Roman Tongeren quickly became one of the largest Gallo-Roman administrative and military towns in the first century.

Typical Roman buildings were built in town, while villas and mound graves (tumuli) dotted the surrounding area.

Julian gave ambiguous replies and then after the meetings sent a surprise attack along the Maas or Meuse river, and "they met him with entreaties rather than with resistance, he received the submission of them and their children".

[5] Already in the fourth century, just as the Salian Franks were settling to the north, the city became the center of a Christian diocese under the influence of Saint Servatius, bishop of Tongeren, who died in 384 AD.

The seat of the Tungrian bishopric however eventually moved to nearby Maastricht, after Saint Servatius was buried near the Roman town there.

In 1977 the neighbouring municipalities of Berg, Diets-Heur, Henis, 's-Herenelderen, Koninksem, Lauw, Mal, Neerrepen, Nerem, Overrepen, Piringen, Riksingen, Rutten, Sluizen, Vreren and Widooie merged into Tongeren.
