For centuries, the strategic location of the current province made it a much-coveted region among Europe's major powers. Romans, Habsburg Spaniards, Prussians, Habsburg Austrians and French have all ruled Limburg. In 1673, Louis XIV personally commanded the siege of Maastricht by French troops. During the siege, one of his brigadiers, Charles de Batz-Castelmore d'Artagnan, perished. He subsequently became known as a major character in The Three Musketeers by Alexandre Dumas, père (1802–1870).
When the Catholic and French-speaking Belgians split away from the mainly Calvinist northern Netherlands in the Belgian Revolution of 1830, the Province of Limburg was at first almost entirely under Belgian rule. However, by the 1839 Treaty of London, the province was divided in two, with the eastern part going to the Netherlands and the western part to Belgium, a division that remains today.
The case files of the 'Brabantse Commissarissen-Deciseurs' (representative inspectors of the Duke of Brabant) are a rich source. Also for researchers of family history. For research about your ancestors, the Genlias website may prove to be very useful.
