The history of Dusseldorf goes back centuries, although it only received city status in the late Middle Ages. The first settlements at the confluence of the Rhine and the Dussel rivers, from which the city received its name, existed as early as the 7th and 8th centuries. However, its official history begins significantly later.
The foundation and first mentions of the city in historical documents became a key stage in its formation. The first written mention of a settlement called "Dusseldorp" dates back to 1135. At that time, it was a small village that grew in a strategically important location. A turning point in the history of Dusseldorf was the year 1288, when Count Adolf V of Berg granted it city status. This occurred after the Count's victory in the Battle of Worringen over the Archbishop of Cologne, who opposed the strengthening of his neighbour.
The further development of the city was determined by several key factors of formation. Firstly, its advantageous geographical location on the banks of the Rhine, one of Europe's main trade arteries, facilitated the growth of trade. Secondly, political will played an important role: in 1385, Dusseldorf became the capital and residence of the Dukes of Berg. This attracted nobility and resources to the city, leading to the construction of a castle and fortifications. The city began to actively expand and strengthen.
Speaking of early cultural and economic features, it is worth noting that upon becoming the capital of the duchy, Dusseldorf began to transform not only into a political centre but also a cultural one. Particularly significant was the contribution of Elector Johann Wilhelm (known as Jan Wellem) in the 17th-18th centuries, who made the city his residence and actively patronised the arts, founding a famous art gallery. Under Duke Wilhelm V in the 16th century, Dusseldorf also became a regional centre for the humanities. The city's economy relied on trade along the Rhine and serving the ducal court, which laid the foundation for its future prosperity.
