Düsseldorf ( , , ; Low Franconian and Ripuarian: Düsseldörp ; archaic ) 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 seventh-largest city in Germany, with a population of 653,253.
The Düssel, from which the city and the borough of Düsseltal take their name, divides into four separate branches within the city, each with its own mouth into the Rhine. Most of Düsseldorf lies on the right bank of the Rhine, and the city has grown together with Neuss, Ratingen, Meerbusch, Erkrath and Monheim am Rhein. Düsseldorf is the central city of the metropolitan region Rhine-Ruhr, that stretches from Bonn via Cologne and Düsseldorf to the Ruhr (from Duisburg via Essen to Dortmund).
The -dorf suffix means "village" in German (English cognate: thorp); its use is unusual for a settlement as large as Düsseldorf. Linguistically, Düsseldorf is the largest city in the German part of the Low Franconian area, dialects that are closely related to Dutch. Düsseldorf Airport is Germany's fourth-busiest airport, serving as the most important international airport for the population of the densely populated Ruhr, Germany's largest urban area.
Mercer's 2012 Quality of Living survey ranked Düsseldorf the sixth most livable city in the world. Düsseldorf is an international business and financial centre, renowned for its fashion and trade fairs, and is headquarters to one Fortune Global 500 and two DAX companies. Messe Düsseldorf organises nearly one fifth of premier trade shows. As second largest city of the Rhineland, Düsseldorf holds Rhenish Carnival celebrations every year in February/March, the Düsseldorf carnival celebrations being the third most popular in Germany after those held in Cologne and Mainz.
There are 22 institutions of higher education in the city including the Heinrich-Heine-Universität Düsseldorf, the university of applied sciences (Hochschule Düsseldorf), the academy of arts (Kunstakademie Düsseldorf, whose members include Joseph Beuys, Emanuel Leutze, August Macke, Gerhard Richter, Sigmar Polke, and Andreas Gursky), and the university of music (Robert-Schumann-Musikhochschule Düsseldorf). The city is also known for its influence on electronic/experimental music (Kraftwerk) and its Japanese community. Düsseldorf is classified as a GaWC Beta+ world city.
History
Early development
When the Roman Empire was strengthening its position throughout Europe, a few Germanic tribes clung on in marshy territory off the eastern banks of the Rhine. In the 7th and 8th centuries, the odd farming or fishing settlement could be found at the point where the small river Düssel flows into the Rhine. It was from such settlements that the city of Düsseldorf grew.
The first written mention of Düsseldorf (then called Dusseldorp in the local Low Rhenish dialect) dates back to 1135. Under Emperor Friedrich Barbarossa the small town of Kaiserswerth to the north of Düsseldorf became a well-fortified outpost, where soldiers kept a watchful eye on every movement on the Rhine. Kaiserswerth eventually became a suburb of Düsseldorf in 1929. In 1186, Düsseldorf came under the rule of the Counts of Berg. 14 August 1288 is one of the most important dates in the history of Düsseldorf. On this day the sovereign Count Adolf VIII of Berg granted the village on the banks of the Düssel town privileges. Before this, a bloody struggle for power had taken place between the Archbishop of Cologne and the count of Berg, culminating in the Battle of Worringen.
The Archbishop of Cologne's forces were wiped out by the forces of the count of Berg who were supported by citizens and farmers of Cologne and Düsseldorf, paving the way for Düsseldorf's elevation to city status, which is commemorated today by a monument on the Burgplatz. The custom of turning cartwheels is credited to the children of Düsseldorf. There are variations of the origin of the cartwheeling children. Today the symbol (Der Radschläger) represents the story and every year the Düsseldorfers celebrate by having a cartwheeling contest. After this battle the relationship between the four cities deteriorated, because they were commercial rivals; it is often said that there is a kind of hostility between the citizens of Cologne and Düsseldorf. Today, it finds its expression mainly in a humorous form (especially during the Rhineland Karneval) and in sports.
