April 1839 CE
Belgium gains recognition as an independent and neutral country comprising West Flanders, East Flanders, Brabant, Antwerp, Hainaut, Namur, and Liège, as well as half of Luxembourg and Limburg, by the Treaty of London signed by the European powers (including the Netherlands) on April 19, 1839.
This gives rise to a Belgian Limburg and Dutch Limburg (the latter being joined—from September 5—to the German Confederation).
