Roer was a department of the French First Republic and later First French Empire in present-day Germany and the Netherlands. It was named after the river Roer (Rur), which flows through the department. It was formed in 1797, when the left bank of the Rhine was occupied by the French. The department was formed from the duchies of Jülich and Cleves; the part of the Archbishopric of Cologne left of the Rhine; the Free City of Aachen; the Prussian part of the duchy of Guelders; and some smaller territories. In 1805 the city of Wesel was added to the department. The capital was Aix-la-Chapelle (Aachen).
