How did the Belgian Revolution affect Luxembourgâs borders?
The Belgian Revolution of 1830 significantly altered the borders of Luxembourg. Following the revolution, the great powers intervened to resolve conflicting claims between the Belgian government and William I of the Netherlands.12
In 1831, it was decided that the territory would be partitioned based on language:
* The French-speaking western portion of the duchy was allotted to Belgium, where it became a province known as Luxembourg.132
* The Luxembourgish-speaking eastern portion was retained by William I and continued to form part of the German Confederation.12
Although William I initially rejected this settlement, he eventually acceded to the arrangement in 1839, at which point the Dutch government officially recognized the new borders.132
