Eupen is the capital of German-speaking Community of Belgium and is a city and municipality in the Belgian province of Liège, 15 kilometres from the German border, from the Dutch border and from the "High Fens" nature reserve. The town is also the capital of the Euroregion Meuse-Rhine.
First mentioned in 1213 as belonging to the Duchy of Limburg, possession of Eupen passed to Brabant, Burgundy, the Holy Roman Empire and France before being given in 1815 to Prussia, which became part of the new German Empire in 1871. In 1919, after the First World War, the Treaty of Versailles transferred Eupen and the nearby municipality of Malmedy from Germany to Belgium.
