Berg (German pronunciation: [bɛʁk] ) was a state—originally a county, later a duchy—in the Rhineland of Germany. Its capital was Düsseldorf. It existed as a distinct political entity from the early 12th to the 19th centuries. It was a member state of the Holy Roman Empire.
The name of the county lives on in the modern geographic term Bergisches Land, often misunderstood as bergiges Land (hilly country).
The United Duchies of Jülich-Cleves-Berg was a territory in the Holy Roman Empire between 1521 and 1614, formed from the personal union of the duchies of Jülich, Cleves and Berg.
The name was resurrected after the Congress of Vienna for the province of Jülich-Cleves-Berg of the Kingdom of Prussia between 1815 and 1822. Its territory is today split between the German state of North Rhine-Westphalia and the Dutch province of Gelderland.
The Bergisches Land (German pronunciation: [ˈbɛʁɡɪʃəs ˈlant], lit. 'Bergian Land') is a low mountain range in the state of North Rhine-Westphalia, Germany, east of the Rhine and south of the Ruhr. The landscape is shaped by forests, meadows, rivers and creeks and contains over twenty artificial lakes. Wuppertal is the biggest town, while the southern part has economic and socio-cultural ties to Cologne. Wuppertal and the neighbouring cities of Remscheid and Solingen form the Bergisches Städtedreieck (Berg City Triangle).
Düsseldorf (German: [ˈdʏsl̩dɔʁf] ) is the capital city of North Rhine-Westphalia, the most populous state of Germany. It is the second-largest city in the state after Cologne and the sixth-largest city in Germany, with a 2024 population of 618,685. Most of Düsseldorf lies on the right bank of the Rhine, and the city has grown together with Neuss, Ratingen, Meerbusch, Erkrath 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. In 1946, it became the capital of the newly created state of North Rhine-Westphalia, strengthening its political role.
The Rheinisch-Bergischer Kreis (German pronunciation: [ˈʁaɪnɪʃ ˈbɛʁɡɪʃɐ ˈkʁaɪs], lit. 'Rhine-Berg district') is a Kreis (district) in the Cologne Bonn Region of North Rhine-Westphalia, Germany. Neighboring districts are Kreis Mettman, Oberbergischer Kreis and Rhein-Sieg, and the district-free cities Cologne, Leverkusen, Solingen and Remscheid.
The Zionites were a religious sect in the eighteenth century at Ronsdorf (Duchy of Berg, Germany).
