Mülheim an der Ruhr was granted city rights in 1808, and a century later its population surpassed 100,000, officially making it a major city.
Mülheim an der Ruhr is located to the southwest of Essen in the Ruhr valley. The city consists of 19 districts, 14 of which are located on the right bank of the Ruhr and 5 on the left bank.

The northern foothills of the Rhenish Massif are characterised by the distinctive rock formation of the bare mountain slopes through which run coal-bearing layers which formed during the carboniferous period. Here the Ruhr cuts more than 50 meters deep into this Mittelgebirge. This natural erosion partly uncovered these mineable black coal deposits, which enabled their exploration and extraction using adits. However, the coal-rich layers became ever deeper as one progressed northward, which required setting up mines to extract the black coal. In contrast, the broad bayou (dead arm of a river) of Styrum borough is characteristic of the features of the Lower Rhine Plain.
Mülheim was chartered in 1808. Between 1878 and 1929, Mülheim absorbed its neighboring towns, including Broich and Heissen. Later, during World War II, forced laborers of the 3rd SS construction brigade were dispatched in the town by the Nazis in 1943.
The U18 metro line connects the city with Essen.
The nearest airport is Düsseldorf Airport, located south west of Mülheim. Mülheim also shares an Airfield with Essen.

Mülheim is home to two Max Planck Institutes, a university campus, and various other educational and scientific institutions.
Mülheim an der Ruhr has a longstanding industrial heritage as part of the Ruhrgebiet, historically focused on coal mining, steel, and chemicals. While heavy industry has declined, the city has shifted towards logistics, retail, scientific research, and high-value services.
Mülheim has developed as a local logistics and services center within North Rhine-Westphalia, supported by its proximity to Düsseldorf, Essen, and the Rhine-Ruhr metropolitan regionâÂÂs transport infrastructure. The local economy includes a developed retail sector and elements of food distribution, along with growing activity in energy and environmental sciences, partly driven by the presence of research institutions such as the Max Planck Institutes and Ruhr West University of Applied Sciences.
