Düsseldorf

Hilden, Langenfeld, Ratingen, Meerbusch, Dormagen, Erkrath, Solingen and Monheim. Düsseldorf is the central city of Rhine-Ruhr, the second biggest metropolitan region by GDP in the European Union, that stretches from Bonn via Cologne and Düsseldorf to the Ruhr.

Düsseldorf began as a small settlement at the mouth of the Düssel River, gaining city rights in 1288 after the Battle of Worringen. In the Late Middle Ages and Renaissance, it grew into a regional political and cultural centre under the Dukes of Berg and later as the capital of the United Duchies of Jülich-Cleves-Berg. The 17th and 18th centuries saw flourishing arts and architecture, with Düsseldorf becoming known for its court culture and early art academy. During the Napoleonic era, it was briefly part of the Grand Duchy of Berg before coming under Prussian control in 1815, where it industrialised rapidly in the 19th century. During the 20th century, Düsseldorf developed into one of Germany's most important centres for administration, business, and culture.
