Loon, and the rest of the prince-bishopric of Liège, were not joined politically with the rest of what would become Belgium until the French revolution.
Nevertheless, in the 16th, 17th, and 18th centuries the population of Loon was constantly and badly affected by the large-scale international wars of the neighbouring Spanish Netherlands and Dutch Republic, including the Eighty Years' War, the War of the Spanish Succession, the War of the Austrian Succession, the Seven Years' War, and even the Brabant Revolution.
During this period the region's episcopal government was often unable to maintain law and order, and the economy of the area was often desperately bad, affected by plundering soldiers and gangs of thieves such as the "Bokkenrijders".
Nevertheless, the population contained strongly conservative Catholic elements, and not only supported the conservative Brabant revolution, but also rebelled unsuccessfully against the revolutionary French regime in the Peasants' War of 1798.

The modern Limburg region, containing the Belgian and Dutch provinces of that name, were first united within one province while under the power of revolutionary France, and later the Napoleonic empire, but then under the name of the French department of the Lower Meuse (Maas).
After Napoleon's defeat, a united Kingdom of the Netherlands was formed, containing modern Belgium, Luxembourg, and the Netherlands.
While it kept many of the French provincial boundaries, the first king, William I, insisted that the name be changed to the "Province of Limburg", based on the name of the medieval Duchy of Limburg.
The only part of Belgian or Dutch Limburg which was really in the Duchy of Limburg is the extreme east of Voeren, the villages of Teuven and Remersdaal, and these only became part of Belgian Limburg in 1977.

After the Belgian Revolution of 1830, the province of Limburg was at first almost entirely under Belgian rule, but the status of both Limburg and Luxembourg became unclear.
During the "Ten days campaign", 2–12 August 1831, Dutch armies entered Belgium and took control of several Belgian cities in order to negotiate from a stronger position.
Several Belgian militias and armies were easily defeated including the Belgian Army of the Meuse near Hasselt, on 8 August.
The French and British intervened, leading to a ceasefire.

After a Conference in London, they signed a treaty in 1839 and established after that both Limburg and Luxemburg would be split between the two states.
That happened; Limburg was split into so-called Dutch Limburg and Belgian Limburg.
