Question: Carausius was from which province, today a part of Belgium and Luxembourg?
Context: Luxembourg wine is primarily produced in the southeastern part of the Grand Duchy of Luxembourg, with vineyards overlooking the Moselle River.  Along this river, which for 42 km makes up part of the border between Luxembourg and Germany, wine is made in three countries.  There is a continuous history of winemaking along Moselle and in Luxembourg going back to Ancient Roman times.  Wine production in 2006/07 was 123,652 hectoliter from 1237 ha of vineyards.  Out of total wine exports of 87,776 hectoliter in 2005/06, 71,726 hectoliter or 82% was exported to nearby Belgium.  Exports to Germany was the second largest at 8,168 hectoliter, or 9%, and is to a large extent made up of base wine in bulk for the production of blended Sekt rather than being sold bottled with "Luxembourg" anywhere on the label.  Therefore, very little Luxembourg wine is seen outside Luxembourg and Belgium. The history of Belgium predates the founding of the modern state of that name in 1830.  Belgium's history is intertwined with those of its neighbours: the Netherlands, Germany, France and Luxembourg.  For most of its history, what is now Belgium was either a part of a larger territory, such as the Carolingian Empire, or divided into a number of smaller states, prominent among them being the Duchy of Brabant, the County of Flanders, the Prince-Bishopric of Liège and County of Luxembourg.  Due to its strategic location and the many armies fighting on its soil, since the Thirty Years' War (1618–1648), Belgium has often been called the "battlefield of Europe" or the "cockpit of Europe".  It is also remarkable as a European nation which contains, and is divided by, a language boundary between Latin-derived French and Germanic Dutch. Gallia Belgica ("Belgic Gaul") was a province of the Roman empire located in the north-eastern part of Roman Gaul, in what is today primarily Belgium, Luxembourg and the Netherlands. The Attert (Luxembourgish: "Atert" ) is a river flowing through Belgium and Luxembourg, left tributary of the Alzette.  Its length is 38 km , of which 32 km are in Luxembourg and 6 km in Belgium.  Its source is in Nobressart, north-west of Arlon, in the Belgian province Luxembourg.  It flows into the river Alzette at Colmar-Berg.  It flows through the village of Attert in Belgium, and the towns of Redange, Useldange, Boevange-sur-Attert, and Bissen in Luxembourg. Forêts was a department of the French First Republic, and later the First French Empire, in present-day Belgium, Luxembourg and Germany.  Its name, meaning 'forests', comes from the Ardennes forests.  It was formed on 24 October 1795, after the Southern Netherlands had been annexed by France on 1 October.  Before the occupation, the territory was part of the Duchy of Luxembourg and the Duchy of Bouillon.  Its capital was Luxembourg City. Orangism was a movement in the 19th century Grand Duchy of Luxembourg favouring the personal union of the Netherlands and Luxembourg under the House of Orange-Nassau.  Made up of many notable figures, mainly nobles and Roman Catholic clergy, they were moderate liberals or conservative-liberals and slightly anti-clerical.  At first they favoured maintaining the Grand Duchy's autonomous status and, especially during the Belgian Revolution, opposed it being merged into Belgium.  In the end the western part of the Grand Duchy (the present province of Luxembourg) passed to Belgium, whilst the eastern part and the Orange grand duchy continued as an independent state.  In 1890 the heads of the House of Orange were grand dukes of Luxembourg, but on the death of king and grand duke William III in 1890 he was succeeded by his relation Adolphe as grand duke since Luxembourg's constitution did not allow a woman (Princess Wilhelmina) to hold the throne.  The movement's newsletter was the "Journal de la Ville et du Pays Luxembourg". Marcus Aurelius Mausaeus Valerius Carausius (died 293) was a military commander of the Roman Empire in the 3rd century.  He was a Menapian from Belgic Gaul, who usurped power in 286, during the Carausian Revolt, declaring himself emperor in Britain and northern Gaul (Imperium Britanniarum).  He did this only 13 years after the Gallic Empire of the Batavian Postumus was ended in 273.  He held power for seven years, fashioning the name "Emperor of the North" for himself, before being assassinated by his finance minister Allectus. The German invasion of Luxembourg was part of Case Yellow (German: "Fall Gelb" ), the German invasion of the Low Countries (Belgium, Luxembourg and the Netherlands) and France during World War II.  The battle began on 10 May 1940 and lasted just one day.  Facing only light resistance, Luxembourg was quickly occupied.  The Luxembourgish government, and Grand Duchess Charlotte, managed to escape the country and a government-in-exile was created in London. Luxembourg (French: "Luxembourg" ; Dutch: "" ; German: "Luxemburg" ; Luxembourgish: "Lëtzebuerg" ; Walloon: "Lussimbork" ) is the southernmost province of Wallonia and of Belgium.  It borders on (clockwise from the east) the country of Luxembourg, France, and the Belgian provinces of Namur and Liège.  Its capital is Arlon (Luxembourgish: "Arel" , Dutch: "Aarlen" ), in the south-east of the province. RTL Radio is a German commercial radio station based in Berlin and the part of the RTL Group.
