Aldenhoven

The Battle of Aldenhoven (1 March 1793) saw the Habsburg Austrian army commanded by Prince Josias of Saxe-Coburg-Saalfeld attack a Republican French force under René Joseph de Lanoue. The Austrians successfully crossed the Roer River and engaged in a cavalry charge led by Archduke Charles, Duke of Teschen which routed the French and inflicted heavy losses. The War of the First Coalition battle occurred near Aldenhoven, a city in North Rhine-Westphalia, Germany located about 55 kilometres (34 mi) west of Cologne. After a victory in the Battle of Jemappes on 6 November 1792, the French army of Charles Francois Dumouriez conquered most of the Austrian Netherlands. That winter, Dumouriez attempted to overrun the Dutch Republic while Francisco de Miranda besieged Maastricht, covered by Lanoue's troops along the Roer. Sent by the Austrian government to reconquer Belgium, Coburg's troops attacked early on the morning of 1 March and dispersed the French. The Battle of Neerwinden on the 18th of March would decide who controlled the Austrian Netherlands.

The Battle of Aldenhoven or Battle of the Roer (2 October 1794) saw a Republican French army commanded by Jean Baptiste Jourdan defeat a Habsburg army under François Sébastien Charles Joseph de Croix, Count of Clerfayt which was defending the line of the Roer River. A key crossing was won by the French right wing at Düren after heavy fighting. The Austrian retreat from the Roer conceded control of the west bank of the Rhine River to France. The battle occurred during the War of the First Coalition, part of a wider conflict called the Wars of the French Revolution. Aldenhoven is located in the state of North Rhine-Westphalia in Germany about 21 kilometres (13 mi) northeast of Aachen.

Langweiler is an archaeological site situated in the Merzbach Valley on the Aldenhovener Plateau of western Germany. Systematic excavations have revealed evidence of 160 houses from eight distinct settlement sites, plus three enclosures and a cemetery, belonging to the period 5300-4900 BC. The site is a key region for understanding the nature of the earliest farming societies in west-central Europe (Bandkeramik era). Extensive surveys done from 1973 to 1981 contributed to recovery of the largest settlements in the valley before destruction of the area for mining.: 5 

The Blausteinsee Leisure and Recreation Area is an artificial lake north of the Eschweiler municipality in the Aachen district of North Rhine-Westphalia, Germany. Its area is around 100 hectares and depth is 46m. It was created during the regeneration of the Zukunft opencast coal mine in the Rhineland coalfield, made by flooding the pit left by the mine with water. Today, the lake is a holiday area for the surrounding towns. The surface of the lake is 129 metres above sea level and its volume is around 25 million cubic metres. The filling of the lake began in 1994. The owner of the Blausteinsee is the Blausteinsee Leisure Centre GmbH, which was founded as a support organization in 1982 by the municipalities of Aldenhoven, Alsdorf, Eschweiler, Stolberg and Würselen. The aim of this company is to create and maintain an attractive leisure and recreational area for the people of the Aachen region, along with coordination of activities on and around the lake.

The Duchy of Jülich (German: Herzogtum Jülich; Dutch: Hertogdom Gulik; French: Duché de Juliers) comprised a state within the Holy Roman Empire from the 11th to the 18th centuries. The duchy lay west of the Rhine river and was bordered by the Electorate of Cologne to the east and the Duchy of Limburg to the west. It had territories on both sides of the river Rur, around its capital Jülich – the former Roman Iuliacum – in the lower Rhineland. The duchy amalgamated with the County of Berg beyond the Rhine in 1423, and from then on also became known as Jülich-Berg. Later it became part of the United Duchies of Jülich-Cleves-Berg. Its territory lies in present-day Germany (part of North Rhine-Westphalia) and in the present-day Netherlands (part of the Limburg province), its population sharing the same Limburgish dialect.
