In 50 BC today’s Maastricht was a site of a Roman settlement called Trajectum ad Mosam (“Ford on the Meuse”). It is uncertain whether the Romans have first founded the settlement at the river Meuse, from which the city derives its name. It is known however, that Celts have lived there around 500 BC.
Between 382 and 721 it was the seat of a bishop and received city rights in 1204. After this the town was held by the dukes of Brabant, under the joint sovereignty of Brabant and the prince-bishops of Liège in 1284 and of Liège and the Dutch Estates-General in 1632.
The city was taken by the Spanish in 1579, by Prince Frederick Henry of Orange in 1632, and by the French in 1673, 1748, and 1794. However, it resisted the Belgians in 1830–32.
Maastricht was involved in WWII as early as the first day of the German invasion of the Low Countries in 1940. However, it also became the first liberated Dutch town in 1944.
Maastricht will forever play an important part in the history of the European Union. The city is famous for the signing of the Maastricht Treaty, the document that calls for the establishment of the EU, on 7 February 1992 by the members of the European Communities..
