In the 7th or 8th century there was a fishing or farming settlement at the place where the little river Dussel (which gave the name to the city) flows into the Rhine. Kaiserswerth is the first part of the city to be mentioned in writing. This was in 1135. Kaiserswerth became part of Düsseldorf in 1927.
In 1186 the Counts of Berg got to rule Düsseldorf and they made it their residence in 1280.
On 14th of August 1288 there was a great battle between the Archbishop of Cologne and the Duke of Limburg against the Duke of Brabant and the Count of Berg. The Duke of Brabant won and the Archbishop of Cologne became a prisoner of the Count of Berg. So he could not do anything against Düsseldorf getting the status of a city. So Düsseldorf became a city with full City Rights in 1288.
The Counts of Berg became more and more powerful and Düsseldorf became the capital of the Duchy of Berg-Mark-Kleve-Jülich in 1380.
in 1680 the Dukes of Berg-Kleve-Mark-Jülich died out and after some struggles the Earls of Palatine (they were Prince-Electors) became the new rulers of Düsseldorf. The most important duke of this line was Johann Wilhelm II. (1690-1716), called Jan Wellem. After Johann Wilhelm the Dukes moved to their new seat in Heidelberg, because they also got to rule the Duchy of Bavaria.
In the Napoleonic Wars the French won the Duchy and Düsseldorf. Napoleon gave the Duchy of Berg-Jülich to one of his generals, who married one of his nieces. This general became later King of Naples.
In the Industrial Revolution in the 19th century Düsseldorf grew a lot and had more than 100,000 inhabitants in 1882. This number had doubled by 1892.
Düsseldorf was almost completely destroyed in World War II. In 1946 Düsseldorf became capital of North Rhine-Westphalia.
