of the territory became part of the French département of Meuse-Inférieure, along with Dutch Limburg to the east of the Maas. After the defeat of Napoleon, the département became part of the new United Kingdom of the Netherlands in 1815, and received its modern name of Limburg as a way for the kingdom to preserve the old title of the medieval Duchy of Limburg, which was nearby. However, in 1830, Belgium was created, splitting the Kingdom, and the position of Limburg and Luxemburg became a cause of conflict between the two resulting Kingdoms. In 1839, under international arbitration, it was finally decided to split Limburg and Luxemburg into their two modern parts.
