Neutral Moresnet
On June 28, 1919, the Treaty of Versailles settled the dispute that had created the neutral territory a century earlier by awarding Neutral Moresnet, along with Prussian Moresnet and the German municipalities of Eupen and Malmedy, to Belgium. The treaty became effective on 10 January 1920, ending both Grignard's term as mayor and the existence of Neutral Moresnet, which became the Belgian municipality of Kelmis.
