Pont-à-Mousson (pɔ̃.t‿a.musɔ̃) is a commune in the Meurthe-et-Moselle department in north-eastern France. Its inhabitants are known as Mussipontains in French. It is an industrial town (mainly steel industry), situated on the river Moselle. Pont-à-Mousson has several historical monuments, including the 18th century Premonstratensian abbey. In 2018, 14,434 people lived in the town, while its agglomeration had a population of 23,824. In 1572 Cardinal Charles of Lorraine established a Jesuit university at Pont-à-Mousson. With the Protestant Revolution building in the German-speaking lands, still part of the Holy Roman Empire, directly to the east, and the Duchy of Lorraine vulnerable to pressure from an increasingly assertive French state directly to the west, the Duchy participated in the wars of religion on the side of the Counter-Reformation. The Tridentine strategy promulgated by the Holy See involved the creation of a "Roman Catholic backbone" (sometimes termed the Lotharingian axis from the territories, including Lorraine, between France and the Habsburg Empire). During the seventeenth century the university grew rapidly until there were about 2,000 students. There were four faculties covering theology, the arts, law and medicine. Students were drawn from across western and central Europe. Over time a rivalry grew up between students in the St Martin district, located on the right-bank of the river Moselle and dominated by Jesuits, and the left-bank students based in the St Laurent quarter and considered the rowdier of the two student tribes. Rivalry peaked with the violent "printers' battles" when the rival factions were known respectively as the "Ponti Mussoni" and the "Mussiponti". The "Mussiponti" won, and in the region the inhabitants of the town became known thereafter as "Mussipontains/Mussipontines". The Duchy of Lorraine became French following the death in 1766 of Duke Stanisław Leszczyński, and in 1769 Louis XV had the Jesuit Academy transferred to Nancy.
